This application is a continuation of International Application No. PCT/US2014/058491, filed Sep. 30, 2014, which claims the benefit of U.S. Provisional Application No. 61/884,853, filed Sep. 30, 2013.
STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENTThis invention was made with government support under grant numbers R37 HL53949 and PO1 HL108794 awarded by the National Institutes of Health. The government has certain rights in this invention.
BACKGROUND OF THE INVENTIONFibrosis is a pathologic process, characterized by overproduction of extracellular matrix (ECM) as a response to tissue injury. Nearly 45% of all deaths in the developed world can be attributed to some type of chronic fibroproliferative disease. Despite their high prevalence, current therapeutic options for fibrotic diseases are quite limited to elimination of triggering stimuli and organ transplantation. No effective agent exists that can directly halt the disease progression at the cellular level, which represents a major unmet medical need. Pharmacological modulation of the αvβ1 integrin by small molecules presents one route to test the role of the αvβ1 integrin in tissue fibrosis. Most integrins contain either an αv chain or β1 chain, and targeting either subunit by itself provides little specificity. Accordingly, there is a need in the art for potent, selective αvβ1 integrin inhibitors. Provided herein are solutions to these and other problems in the art.
BRIEF SUMMARY OF THE INVENTIONHerein are provided, inter alia, methods for treating fibrosis using an αvβ1 inhibitor and compositions of αvβ1 inhibitors.

The abbreviations used herein have their conventional meaning within the chemical and biological arts. The chemical structures and formulae set forth herein are constructed according to the standard rules of chemical valency known in the chemical arts.
Where substituent groups are specified by their conventional chemical formulae, written from left to right, they equally encompass the chemically identical substituents that would result from writing the structure from right to left, e.g., —CH2O— is equivalent to —OCH2—.
The term “alkyl,” by itself or as part of another substituent, means, unless otherwise stated, a straight (i.e., unbranched) or branched carbon chain (or carbon), or combination thereof, which may be fully saturated, mono- or polyunsaturated and can include mono-, di- and multivalent radicals, having the number of carbon atoms designated (i.e., C1-C10 means one to ten carbons). Alkyl is an uncyclized chain. Examples of saturated hydrocarbon radicals include, but are not limited to, groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, t-butyl, isobutyl, sec-butyl, (cyclohexyl)methyl, homologs and isomers of, for example, n-pentyl, n-hexyl, n-heptyl, n-octyl, and the like. An unsaturated alkyl group is one having one or more double bonds or triple bonds. Examples of unsaturated alkyl groups include, but are not limited to, vinyl, 2-propenyl, crotyl, 2-isopentenyl, 2-(butadienyl), 2,4-pentadienyl, 3-(1,4-pentadienyl), ethynyl, 1- and 3-propynyl, 3-butynyl, and the higher homologs and isomers. An alkoxy is an alkyl attached to the remainder of the molecule via an oxygen linker (—O—).
The term “alkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkyl, as exemplified, but not limited by, —CH2CH2CH2CH2—. Typically, an alkyl (or alkylene) group will have from 1 to 24 carbon atoms, with those groups having 10 or fewer carbon atoms being preferred herein. A “lower alkyl” or “lower alkylene” is a shorter chain alkyl or alkylene group, generally having eight or fewer carbon atoms. The term “alkenylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from an alkene.
The term “heteroalkyl,” by itself or in combination with another term, means, unless otherwise stated, a stable straight or branched chain, or combinations thereof, including at least one carbon atom and at least one heteroatom selected from the group consisting of O, N, P, Si, and S, and wherein the nitrogen and sulfur atoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. The heteroatom(s) O, N, P, S, B, As, and Si may be placed at any interior position of the heteroalkyl group or at the position at which the alkyl group is attached to the remainder of the molecule. Heteroalkyl is an uncyclized chain. Examples include, but are not limited to: —CH2—CH2—O—CH3, —CH2—CH2—NH—CH3, —CH2—CH2—N(CH3)—CH3, —CH2—S—CH2—CH3, —CH2—CH2, —S(O)—CH3, —CH2—CH2—S(O)2—CH3, —CH═CH—O—CH3, —Si(CH3)3, —CH2—CH═N—OCH3, —CH═CH—N(CH3)—CH3, —O—CH3, —O—CH2—CH3, and —CN. Up to two or three heteroatoms may be consecutive, such as, for example, —CH2—NH—OCH3 and —CH2—O—Si(CH3)3.
Similarly, the term “heteroalkylene,” by itself or as part of another substituent, means, unless otherwise stated, a divalent radical derived from heteroalkyl, as exemplified, but not limited by, —CH2—CH2—S—CH2—CH2— and —CH2—S—CH2—CH2—NH—CH2—. For heteroalkylene groups, heteroatoms can also occupy either or both of the chain termini (e.g., alkyleneoxy, alkylenedioxy, alkyleneamino, alkylenediamino, and the like). Still further, for alkylene and heteroalkylene linking groups, no orientation of the linking group is implied by the direction in which the formula of the linking group is written. For example, the formula —C(O)2R′— represents both —C(O)2R′— and —R′C(O)2—. As described above, heteroalkyl groups, as used herein, include those groups that are attached to the remainder of the molecule through a heteroatom, such as —C(O)R′, —C(O)NR′, —NR′R″, —OR′, —SR′, and/or —SO2R′. Where “heteroalkyl” is recited, followed by recitations of specific heteroalkyl groups, such as —NR′R″ or the like, it will be understood that the terms heteroalkyl and —NR′R″ are not redundant or mutually exclusive. Rather, the specific heteroalkyl groups are recited to add clarity. Thus, the term “heteroalkyl” should not be interpreted herein as excluding specific heteroalkyl groups, such as —NR′R″ or the like.
The terms “cycloalkyl” and “heterocycloalkyl,” by themselves or in combination with other terms, mean, unless otherwise stated, cyclic versions of “alkyl” and “heteroalkyl,” respectively. Cycloalkyl and heteroalkyl are not aromatic. Additionally, for heterocycloalkyl, a heteroatom can occupy the position at which the heterocycle is attached to the remainder of the molecule. Examples of cycloalkyl include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, 1-cyclohexenyl, 3-cyclohexenyl, cycloheptyl, and the like. Examples of heterocycloalkyl include, but are not limited to, 1-(1,2,5,6-tetrahydropyridyl), 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-morpholinyl, 3-morpholinyl, tetrahydrofuran-2-yl, tetrahydrofuran-3-yl, tetrahydrothien-2-yl, tetrahydrothien-3-yl, 1-piperazinyl, 2-piperazinyl, and the like. A “cycloalkylene” and a “heterocycloalkylene,” alone or as part of another substituent, means a divalent radical derived from a cycloalkyl and heterocycloalkyl, respectively.
The terms “halo” or “halogen,” by themselves or as part of another substituent, mean, unless otherwise stated, a fluorine, chlorine, bromine, or iodine atom. Additionally, terms such as “haloalkyl” are meant to include monohaloalkyl and polyhaloalkyl. For example, the term “halo(C1-C4)alkyl” includes, but is not limited to, fluoromethyl, difluoromethyl, trifluoromethyl, 2,2,2-trifluoroethyl, 4-chlorobutyl, 3-bromopropyl, and the like.
The term “acyl” means, unless otherwise stated, —C(O)R where R is a substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heteroaryl.
The term “aryl” means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent, which can be a single ring or multiple rings (preferably from 1 to 3 rings) that are fused together (i.e., a fused ring aryl) or linked covalently. A fused ring aryl refers to multiple rings fused together wherein at least one of the fused rings is an aryl ring. The term “heteroaryl” refers to aryl groups (or rings) that contain at least one heteroatom such as N, O, or S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. Thus, the term “heteroaryl” includes fused ring heteroaryl groups (i.e., multiple rings fused together wherein at least one of the fused rings is a heteroaromatic ring). A 5,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 5 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. Likewise, a 6,6-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 6 members, and wherein at least one ring is a heteroaryl ring. And a 6,5-fused ring heteroarylene refers to two rings fused together, wherein one ring has 6 members and the other ring has 5 members, and wherein at least one ring is a heteroaryl ring. A heteroaryl group can be attached to the remainder of the molecule through a carbon or heteroatom. Non-limiting examples of aryl and heteroaryl groups include phenyl, naphthyl, pyrrolyl, pyrazolyl, pyridazinyl, triazinyl, pyrimidinyl, imidazolyl, pyrazinyl, purinyl, oxazolyl, isoxazolyl, thiazolyl, furyl, thienyl, pyridyl, pyrimidyl, benzothiazolyl, benzoxazoyl benzimidazolyl, benzofuran, isobenzofuranyl, indolyl, isoindolyl, benzothiophenyl, isoquinolyl, quinoxalinyl, quinolyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl. Substituents for each of the above noted aryl and heteroaryl ring systems are selected from the group of acceptable substituents described below. An “arylene” and a “heteroarylene,” alone or as part of another substituent, mean a divalent radical derived from an aryl and heteroaryl, respectively. A heteroaryl group substituent may be —O— bonded to a ring heteroatom nitrogen.
Spirocyclic rings are two or more rings wherein adjacent rings are attached through a single atom. The individual rings within spirocyclic rings may be identical or different. Individual rings in spirocyclic rings may be substituted or unsubstituted and may have different substituents from other individual rings within a set of spirocyclic rings. Possible substituents for individual rings within spirocyclic rings are the possible substituents for the same ring when not part of spirocyclic rings (e.g. substituents for cycloalkyl or heterocycloalkyl rings). Spirocylic rings may be substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylene, substituted or unsubstituted heterocycloalkyl or substituted or unsubstituted heterocycloalkylene and individual rings within a spirocyclic ring group may be any of the immediately previous list, including having all rings of one type (e.g. all rings being substituted heterocycloalkylene wherein each ring may be the same or different substituted heterocycloalkylene). When referring to a spirocyclic ring system, heterocyclic spirocyclic rings means a spirocyclic rings wherein at least one ring is a heterocyclic ring and wherein each ring may be a different ring. When referring to a spirocyclic ring system, substituted spirocyclic rings means that at least one ring is substituted and each substituent may optionally be different.
The symbol “” denotes the point of attachment of a chemical moiety to the remainder of a molecule or chemical formula.
The term “oxo,” as used herein, means an oxygen that is double bonded to a carbon atom.
The term “alkylarylene” as an arylene moiety covalently bonded to an alkylene moiety (also referred to herein as an alkylene linker). In embodiments, the alkylarylene group has the formula:
An alkylarylene moiety may be substituted (e.g. with a substituent group) on the alkylene moiety or the arylene linker (e.g. at carbons 2, 3, 4, or 6) with halogen, oxo, —N3, —CF3, —CCl3, —CBr3, —CI3, —CN, —CHO, —OH, —NH2, —COOH, —CONH2, —NO2, —SH, —SO2, —SO2Cl, —SO2CH3—SO3H, —OSO3H, —SO2NH2, —NHNH2, —ONH2, —NHC(O)NHNH2, substituted or unsubstituted C1-C5 alkyl or substituted or unsubstituted 2 to 5 membered heteroalkyl). In embodiments, the alkylarylene is unsubstituted.
Each of the above terms (e.g., “alkyl,” “heteroalkyl,” “aryl,” and “heteroaryl”) includes both substituted and unsubstituted forms of the indicated radical. Preferred substituents for each type of radical are provided below.
Substituents for the alkyl and heteroalkyl radicals (including those groups often referred to as alkylene, alkenyl, heteroalkylene, heteroalkenyl, alkynyl, cycloalkyl, heterocycloalkyl, cycloalkenyl, and heterocycloalkenyl) can be one or more of a variety of groups selected from, but not limited to, —OR′, ═O, ═NR′, ═N—OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R, —C(O)R′, —CO2R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R″, —NR″C(O)2R′, —NR—C(NR′R″R′″)═NR′″, —NR—C(NR′R″)═NR′″, —S(O)R′, —S(O)2R′, —S(O)2NR′R″, —NRSO2R′, —NR′NR″R′″, —ONR′R″, —NR′C(O)NR″NR″R′″, —CN, —NO2, —NR′SO2R″, —NR′C(O)R″, —NR′C(O)—OR″, —NR′OR″, in a number ranging from zero to (2m′+1), where m′ is the total number of carbon atoms in such radical. R, R′, R″, R′″, and R″″ each preferably independently refer to hydrogen, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl (e.g., aryl substituted with 1-3 halogens), substituted or unsubstituted heteroaryl, substituted or unsubstituted alkyl, alkoxy, or thioalkoxy groups, or arylalkyl groups. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′, and R′″ group when more than one of these groups is present. When R′ and R″ are attached to the same nitrogen atom, they can be combined with the nitrogen atom to form a 4-, 5-, 6-, or 7-membered ring. For example, —NR′R″ includes, but is not limited to, 1-pyrrolidinyl and 4-morpholinyl. From the above discussion of substituents, one of skill in the art will understand that the term “alkyl” is meant to include groups including carbon atoms bound to groups other than hydrogen groups, such as haloalkyl (e.g., —CF3 and —CH2CF3) and acyl (e.g., —C(O)CH3, —C(O)CF3, —C(O)CH2OCH3, and the like).
Similar to the substituents described for the alkyl radical, substituents for the aryl and heteroaryl groups are varied and are selected from, for example: —OR′, —NR′R″, —SR′, -halogen, —SiR′R″R′″, —OC(O)R′, —C(O)R′, —CO2R′, —CONR′R″, —OC(O)NR′R″, —NR″C(O)R′, —NR′—C(O)NR″R′″, —NR″C(O)2R′, —NR—C(NR′R″R′″)═NR′″, —NR—C(NR′R″)═NR′″, —S(O)R′, —S(O)2R′, —S(O)2NR′R″, —NRSO2R′, —NR′NR″R′″, —ONR′R″, —NR′C(O)NR″NR′″R″, —CN, —NO2, —R′, —N3, —CH(Ph)2, fluoro(C1-C4)alkoxy, and fluoro(C1-C4)alkyl, —NR′SO2R″, —NR′C(O)R″, —NR′C(O)—OR″, —NR′OR″, in a number ranging from zero to the total number of open valences on the aromatic ring system; and where R′, R″, R′″, and R″ are preferably independently selected from hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, and substituted or unsubstituted heteroaryl. When a compound described herein includes more than one R group, for example, each of the R groups is independently selected as are each R′, R″, R′″, and R″ groups when more than one of these groups is present.
Substituents for rings (e.g. cycloalkyl, heterocycloalkyl, aryl, heteroaryl, cycloalkylene, heterocycloalkylene, arylene, or heteroarylene) may be depicted as substituents on the ring rather than on a specific atom of a ring (commonly referred to as a floating substituent). In such a case, the substituent may be attached to any of the ring atoms (obeying the rules of chemical valency) and in the case of fused rings or spirocyclic rings, a substituent depicted as associated with one member of the fused rings or spirocyclic rings (a floating substituent on a single ring), may be a substituent on any of the fused rings or spirocyclic rings (a floating substituent on multiple rings). When a substituent is attached to a ring, but not a specific atom (a floating substituent), and a subscript for the substituent is an integer greater than one, the multiple substituents may be on the same atom, same ring, different atoms, different fused rings, different spirocyclic rings, and each substituent may optionally be different. Where a point of attachment of a ring to the remainder of a molecule is not limited to a single atom (a floating substituent), the attachment point may be any atom of the ring and in the case of a fused ring or spirocyclic ring, any atom of any of the fused rings or spirocyclic rings while obeying the rules of chemical valency. Where a ring, fused rings, or spirocyclic rings contain one or more ring heteroatoms and the ring, fused rings, or spirocyclic rings are shown with one more floating substituents (including, but not limited to, points of attachment to the remainder of the molecule), the floating substituents may be bonded to the heteroatoms. Where the ring heteroatoms are shown bound to one or more hydrogens (e.g. a ring nitrogen with two bonds to ring atoms and a third bond to a hydrogen) in the structure or formula with the floating substituent, when the heteroatom is bonded to the floating substituent, the substituent will be understood to replace the hydrogen, while obeying the rules of chemical valency.
Two or more substituents may optionally be joined to form aryl, heteroaryl, cycloalkyl, or heterocycloalkyl groups. Such so-called ring-forming substituents are typically, though not necessarily, found attached to a cyclic base structure. In one embodiment, the ring-forming substituents are attached to adjacent members of the base structure. For example, two ring-forming substituents attached to adjacent members of a cyclic base structure create a fused ring structure. In another embodiment, the ring-forming substituents are attached to a single member of the base structure. For example, two ring-forming substituents attached to a single member of a cyclic base structure create a spirocyclic structure. In yet another embodiment, the ring-forming substituents are attached to non-adjacent members of the base structure.
Two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally form a ring of the formula -T-C(O)—(CRR′)q—U—, wherein T and U are independently —NR—, —O—, —CRR′—, or a single bond, and q is an integer of from 0 to 3.
Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula -A-(CH2)r—B—, wherein A and B are independently —CRR′—, —O—, —NR—, —S—, —S(O)—, —S(O)2—, —S(O)2NR′—, or a single bond, and r is an integer of from 1 to 4. One of the single bonds of the new ring so formed may optionally be replaced with a double bond. Alternatively, two of the substituents on adjacent atoms of the aryl or heteroaryl ring may optionally be replaced with a substituent of the formula —(CRR′)s—X′—(C″R″R′″)d—, where s and d are independently integers of from 0 to 3, and X is —O—, —NR′—, —S—, —S(O)—, —S(O)2—, or —S(O)2NR′—.

Certain compounds of the present invention possess asymmetric carbon atoms (optical or chiral centers) or double bonds; the enantiomers, racemates, diastereomers, tautomers, geometric isomers, stereoisometric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids, and individual isomers are encompassed within the scope of the present invention. The compounds of the present invention do not include those that are known in art to be too unstable to synthesize and/or isolate. The present invention is meant to include compounds in racemic and optically pure forms. Optically active (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. When the compounds described herein contain olefinic bonds or other centers of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers.
As used herein, the term “isomers” refers to compounds having the same number and kind of atoms, and hence the same molecular weight, but differing in respect to the structural arrangement or configuration of the atoms.
The term “tautomer,” as used herein, refers to one of two or more structural isomers which exist in equilibrium and which are readily converted from one isomeric form to another.
It will be apparent to one skilled in the art that certain compounds of this invention may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the invention.
Unless otherwise stated, structures depicted herein are also meant to include all stereochemical forms of the structure; i.e., the R and S configurations for each asymmetric center. Therefore, single stereochemical isomers as well as enantiomeric and diastereomeric mixtures of the present compounds are within the scope of the invention.
Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by 13C- or 14C-enriched carbon are within the scope of this invention.
Unless otherwise stated, structures depicted herein are also meant to include compounds which differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures except for the replacement of a hydrogen by a deuterium or tritium, or the replacement of a carbon by 13C- or 14C-enriched carbon are within the scope of this invention.
The compounds of the present invention may also contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute such compounds. For example, the compounds may be radiolabeled with radioactive isotopes, such as for example tritium (3H), iodine-125 (125I), or carbon-14 (14C). All isotopic variations of the compounds of the present invention, whether radioactive or not, are encompassed within the scope of the present invention.
It should be noted that throughout the application that alternatives are written in Markush groups, for example, each amino acid position that contains more than one possible amino acid. It is specifically contemplated that each member of the Markush group should be considered separately, thereby comprising another embodiment, and the Markush group is not to be read as a single unit.
“Analog,” or “analogue” is used in accordance with its plain ordinary meaning within Chemistry and Biology and refers to a chemical compound that is structurally similar to another compound (i.e., a so-called “reference” compound) but differs in composition, e.g., in the replacement of one atom by an atom of a different element, or in the presence of a particular functional group, or the replacement of one functional group by another functional group, or the absolute stereochemistry of one or more chiral centers of the reference compound. Accordingly, an analog is a compound that is similar or comparable in function and appearance but not in structure or origin to a reference compound.
The terms “a” or “an,” as used in herein means one or more. In addition, the phrase “substituted with a[n],” as used herein, means the specified group may be substituted with one or more of any or all of the named substituents. For example, where a group, such as an alkyl or heteroaryl group, is “substituted with an unsubstituted C1-C20 alkyl, or unsubstituted 2 to 20 membered heteroalkyl,” the group may contain one or more unsubstituted C1-C20 alkyls, and/or one or more unsubstituted 2 to 20 membered heteroalkyls.
Moreover, where a moiety is substituted with an R substituent, the group may be referred to as “R-substituted.” Where a moiety is R-substituted, the moiety is substituted with at least one R substituent and each R substituent is optionally different. Where a particular R group is present in the description of a chemical genus (such as Formula (I)), a Roman alphabetic symbol may be used to distinguish each appearance of that particular R group. For example, where multiple R13 substituents are present, each R13 substituent may be distinguished as R13A, R13B, R13C, R13D, etc., wherein each of R13A, R13B, R13C, R13D, etc. is defined within the scope of the definition of R13 and optionally differently.
A “detectable moiety” as used herein refers to a moiety that can be covalently or noncovalently attached to a compound or biomolecule that can be detected for instance, using techniques known in the art. In embodiments, the detectable moiety is covalently attached. The detectable moiety may provide for imaging of the attached compound or biomolecule. The detectable moiety may indicate the contacting between two compounds. Exemplary detectable moieties are fluorophores, antibodies, reactive dies, radio-labeled moieties, magnetic contrast agents, and quantum dots. Exemplary fluorophores include fluorescein, rhodamine, GFP, coumarin, FITC, Alexa fluor, Cy3, Cy5, BODIPY, and cyanine dyes. Exemplary radionuclides include Fluorine-18, Gallium-68, and Copper-64. Exemplary magnetic contrast agents include gadolinium, iron oxide and iron platinum, and manganese.
Description of compounds of the present invention are limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding and to give compounds which are not inherently unstable and/or would be known to one of ordinary skill in the art as likely to be unstable under ambient conditions, such as aqueous, neutral, and several known physiological conditions. For example, a heterocycloalkyl or heteroaryl is attached to the remainder of the molecule via a ring heteroatom in compliance with principles of chemical bonding known to those skilled in the art thereby avoiding inherently unstable compounds.
A “test compound” as used herein refers to an experimental compound used in a screening process to identify activity, non-activity, or other modulation of a particularized biological target or pathway.
The term “pharmaceutically acceptable salts” is meant to include salts of the active compounds that are prepared with relatively nontoxic acids or bases, depending on the particular substituents found on the compounds described herein. When compounds of the present invention contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amino, or magnesium salt, or a similar salt. When compounds of the present invention contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, oxalic, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like (see, for example, Berge et al., “Pharmaceutical Salts”, Journal of Pharmaceutical Science, 1977, 66, 1-19). Certain specific compounds of the present invention contain both basic and acidic functionalities that allow the compounds to be converted into either base or acid addition salts.
Thus, the compounds of the present invention may exist as salts, such as with pharmaceutically acceptable acids. The present invention includes such salts. Non-limiting examples of such salts include hydrochlorides, hydrobromides, phosphates, sulfates, methanesulfonates, nitrates, maleates, acetates, citrates, fumarates, proprionates, tartrates (e.g., (+)-tartrates, (−)-tartrates, or mixtures thereof including racemic mixtures), succinates, benzoates, and salts with amino acids such as glutamic acid, and quaternary ammonium salts (e.g. methyl iodide, ethyl iodide, and the like). These salts may be prepared by methods known to those skilled in the art.
The neutral forms of the compounds are preferably regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner. The parent form of the compound may differ from the various salt forms in certain physical properties, such as solubility in polar solvents.
In addition to salt forms, the present invention provides compounds, which are in a prodrug form. Prodrugs of the compounds described herein are those compounds that readily undergo chemical changes under physiological conditions to provide the compounds of the present invention. Prodrugs of the compounds described herein may be converted in vivo after administration. Additionally, prodrugs can be converted to the compounds of the present invention by chemical or biochemical methods in an ex vivo environment, such as, for example, when contacted with a suitable enzyme or chemical reagent.
Certain compounds of the present invention can exist in unsolvated forms as well as solvated forms, including hydrated forms. In general, the solvated forms are equivalent to unsolvated forms and are encompassed within the scope of the present invention. Certain compounds of the present invention may exist in multiple crystalline or amorphous forms. In general, all physical forms are equivalent for the uses contemplated by the present invention and are intended to be within the scope of the present invention.
“Pharmaceutically acceptable excipient” and “pharmaceutically acceptable carrier” refer to a substance that aids the administration of an active agent to and absorption by a subject and can be included in the compositions of the present invention without causing a significant adverse toxicological effect on the patient. Non-limiting examples of pharmaceutically acceptable excipients include water, NaCl, normal saline solutions, lactated Ringer's, normal sucrose, normal glucose, binders, fillers, disintegrants, lubricants, coatings, sweeteners, flavors, salt solutions (such as Ringer's solution), alcohols, oils, gelatins, carbohydrates such as lactose, amylose or starch, fatty acid esters, hydroxymethycellulose, polyvinyl pyrrolidine, and colors, and the like. Such preparations can be sterilized and, if desired, mixed with auxiliary agents such as lubricants, preservatives, stabilizers, wetting agents, emulsifiers, salts for influencing osmotic pressure, buffers, coloring, and/or aromatic substances and the like that do not deleteriously react with the compounds of the invention. One of skill in the art will recognize that other pharmaceutical excipients are useful in the present invention.
The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier providing a capsule in which the active component with or without other carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid dosage forms suitable for oral administration.
An “αvβ1-inhibitor” as used herein refers to a composition (e.g. a compound, nucleic acid, polynucleotide, peptide, protein, or antibody) capable of reducing the activity of αvβ1 integrin when compared to a control compound (e.g. known to have no reduction in αvβ1 integrin activity) or the absence of the αvβ1-inhibitor compound. An “αvβ1-inhibitor compound” refers to a compound (e.g. compounds described herein) that reduce the activity of αvβ1 integrin when compared to a control, such as absence of the compound or a compound with known inactivity. An “αvβ1-inhibitor-antibody” refers to an antibody that reduces the activity of αvβ1 integrin when compared to a control (e.g. the absence of the antibody). An “αvβ1-inhibitor-RGD peptide” refers to a RGD-peptide that reduces the activity of αvβ1 integrin when compared to a control (e.g. the absence of the peptide).
An “αvβ1-specific moiety”, “specific,” “specifically”, “specificity”, or the like of a composition (e.g. a compound, nucleic acid, polynucleotide, peptide, protein, or antibody) refers to the composition's ability to discriminate between particular molecular targets to a significantly greater extent than other proteins in the cell (e.g. a compound having specificity towards αvβ1 integrin binds to αvβ1 integrin whereas the same compound displays little-to-no binding to other integrins such as α5β1, α8β1, αvβ3, αvβ5, or αvβ6). An “αvβ1-specific compound”. An “αvβ1-specific compound” refers to a compound (e.g. compounds described herein) having specificity towards αvβ1 integrin. An “αvβ1-specific antibody” refers to an antibody having specificity towards αvβ1 integrin. An “αvβ1-specific RGD peptide” refers to a RGD peptide having specificity towards αvβ1 integrin.
The terms “αvβ1-selective,” “selective,” or “selectivity” or the like of a compound refers to the composition's (e.g. a compound, nucleic acid, polynucleotide, peptide, protein, or antibody) ability to cause a particular action in a particular molecular target (e.g. a compound having selectivity toward αvβ1 integrin would inhibit only αvβ1). An “αvβ1-selective compound” refers to a compound (e.g. compounds described herein) having selectivity towards αvβ1 integrin. An “αvβ1-selective antibody” refers to an antibody having selectivity towards αvβ1 integrin. An “αvβ1-selective RGD peptide” refers to a RGD peptide having selectivity towards αvβ1 integrin.
The terms “polypeptide,” “peptide” and “protein” are used interchangeably herein to refer to a polymer of amino acid residues, wherein the polymer may optionally be conjugated to a moiety that does not consist of amino acids. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymer.
A polypeptide, or a cell is “recombinant” when it is artificial or engineered, or derived from or contains an artificial or engineered protein or nucleic acid (e.g. non-natural or not wild type). For example, a polynucleotide that is inserted into a vector or any other heterologous location, e.g., in a genome of a recombinant organism, such that it is not associated with nucleotide sequences that normally flank the polynucleotide as it is found in nature is a recombinant polynucleotide. A protein expressed in vitro or in vivo from a recombinant polynucleotide is an example of a recombinant polypeptide. Likewise, a polynucleotide sequence that does not appear in nature, for example a variant of a naturally occurring gene, is recombinant.
“RGD peptide” as used herein refers to a tripeptide comprising Arg., Gly., and Asp. RGD peptides typically act as recognition sequences for integrins and in some embodiments, promote cellular adhesion via integrin binding. RGD peptides as used herein refers to naturally occurring RGD sequences, RGD mimetics (e.g. substitutions of R, G, or D with non-proteinogenic amino acids), RGD peptides covalently bound to a targeting-moiety (e.g. a molecule for targeting the peptide to a specific integrin or specific location in a cell or organism), and cyclized RGD peptides of embodiments described herein. Exemplary RGD peptides include Arg-Gly-Asp, Asp-Gly-Arg, cyclo-Gly-Arg-Gly-Asp-Ser-Pro, and KGD peptides include Cys-Asn-Thr-Leu-Lys-Gly-Asp-Cys and Asn-Thr-Leu-Lys-Gly-Asp, and those found in Ann. Rev. Cell & Dev. Biol., 1996, November, Vol. 12: 697-715 and Proteins, 1992 December; 14(4):509-15.
“Antibody” refers to a polypeptide comprising a framework region from an immunoglobulin gene or fragments thereof that specifically binds and recognizes an antigen. The recognized immunoglobulin genes include the kappa, lambda, alpha, gamma, delta, epsilon, and mu constant region genes, as well as the myriad immunoglobulin variable region genes. Light chains are classified as either kappa or lambda. Heavy chains are classified as gamma, mu, alpha, delta, or epsilon, which in turn define the immunoglobulin classes, IgG, IgM, IgA, IgD and IgE, respectively. Typically, the antigen-binding region of an antibody will be most critical in specificity and affinity of binding.
An exemplary immunoglobulin (antibody) structural unit comprises a tetramer. Each tetramer is composed of two identical pairs of polypeptide chains, each pair having one “light” (about 25 kD) and one “heavy” chain (about 50-70 kD). The N-terminus of each chain defines a variable region of about 100 to 110 or more amino acids primarily responsible for antigen recognition. The terms variable light chain (VL) and variable heavy chain (VH) refer to these light and heavy chains respectively.
Antibodies exist, e.g., as intact immunoglobulins or as a number of well-characterized fragments produced by digestion with various peptidases. Thus, for example, pepsin digests an antibody below the disulfide linkages in the hinge region to produce F(ab)′2, a dimer of Fab which itself is a light chain joined to VH—CH1 by a disulfide bond. The F(ab)′2 may be reduced under mild conditions to break the disulfide linkage in the hinge region, thereby converting the F(ab)′2 dimer into an Fab′ monomer. The Fab′ monomer is essentially Fab with part of the hinge region (see Fundamental Immunology (Paul ed., 3d ed. 1993). While various antibody fragments are defined in terms of the digestion of an intact antibody, one of skill will appreciate that such fragments may be synthesized de novo either chemically or by using recombinant DNA methodology. Thus, the term antibody, as used herein, also includes antibody fragments either produced by the modification of whole antibodies, or those synthesized de novo using recombinant DNA methodologies (e.g., single chain Fv) or those identified using phage display libraries (see, e.g., McCafferty et al., Nature 348:552-554 (1990)).
For preparation of suitable antibodies of the invention and for use according to the invention, e.g., recombinant, monoclonal, or polyclonal antibodies, many techniques known in the art can be used (see, e.g., Kohler & Milstein, Nature 256:495-497 (1975); Kozbor et al., Immunology Today 4: 72 (1983); Cole et al., pp. 77-96 in Monoclonal Antibodies and Cancer Therapy, Alan R. Liss, Inc. (1985); Coligan, Current Protocols in Immunology (1991); Harlow & Lane, Antibodies, A Laboratory Manual (1988); and Goding, Monoclonal Antibodies: Principles and Practice (2d ed. 1986)). The genes encoding the heavy and light chains of an antibody of interest can be cloned from a cell, e.g., the genes encoding a monoclonal antibody can be cloned from a hybridoma and used to produce a recombinant monoclonal antibody. Gene libraries encoding heavy and light chains of monoclonal antibodies can also be made from hybridoma or plasma cells. Random combinations of the heavy and light chain gene products generate a large pool of antibodies with different antigenic specificity (see, e.g., Kuby, Immunology (3rd ed. 1997)). Techniques for the production of single chain antibodies or recombinant antibodies (U.S. Pat. No. 4,946,778, U.S. Pat. No. 4,816,567) can be adapted to produce antibodies to polypeptides of this invention. Also, transgenic mice, or other organisms such as other mammals, may be used to express humanized or human antibodies (see, e.g., U.S. Pat. Nos. 5,545,807; 5,545,806; 5,569,825; 5,625,126; 5,633,425; 5,661,016, Marks et al., Bio/Technology 10:779-783 (1992); Lonberg et al., Nature 368:856-859 (1994); Morrison, Nature 368:812-13 (1994); Fishwild et al., Nature Biotechnology 14:845-51 (1996); Neuberger, Nature Biotechnology 14:826 (1996); and Lonberg & Huszar, Intern. Rev. Immunol. 13:65-93 (1995)). Alternatively, phage display technology can be used to identify antibodies and heteromeric Fab fragments that specifically bind to selected antigens (see, e.g., McCafferty et al., Nature 348:552-554 (1990); Marks et al., Biotechnology 10:779-783 (1992)). Antibodies can also be made bispecific, i.e., able to recognize two different antigens (see, e.g., WO 93/08829, Traunecker et al., EMBO J. 10:3655-3659 (1991); and Suresh et al., Methods in Enzymology 121:210 (1986)). Antibodies can also be heteroconjugates, e.g., two covalently joined antibodies, or immunotoxins (see, e.g., U.S. Pat. No. 4,676,980, WO 91/00360; WO 92/200373; and EP 03089).
Methods for humanizing or primatizing non-human antibodies are well known in the art. Generally, a humanized antibody has one or more amino acid residues introduced into it from a source which is non-human. These non-human amino acid residues are often referred to as import residues, which are typically taken from an import variable domain.
Humanization can be essentially performed following the method of Winter and co-workers (see, e.g., Jones et al., Nature 321:522-525 (1986); Riechmann et al., Nature 332:323-327 (1988); Verhoeyen et al., Science 239:1534-1536 (1988) and Presta, Curr. Op. Struct. Biol. 2:593-596 (1992)), by substituting rodent CDRs or CDR sequences for the corresponding sequences of a human antibody. Accordingly, such humanized antibodies are chimeric antibodies (U.S. Pat. No. 4,816,567), wherein substantially less than an intact human variable domain has been substituted by the corresponding sequence from a non-human species. In practice, humanized antibodies are typically human antibodies in which some CDR residues and possibly some FR residues are substituted by residues from analogous sites in rodent antibodies.
A “chimeric antibody” is an antibody molecule in which (a) the constant region, or a portion thereof, is altered, replaced or exchanged so that the antigen binding site (variable region) is linked to a constant region of a different or altered class, effector function and/or species, or an entirely different molecule which confers new properties to the chimeric antibody, e.g., an enzyme, toxin, hormone, growth factor, drug, etc.; or (b) the variable region, or a portion thereof, is altered, replaced or exchanged with a variable region having a different or altered antigen specificity. The preferred antibodies of, and for use according to the invention include humanized and/or chimeric monoclonal antibodies.
“Contacting” is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g. chemical compounds including biomolecules or cells) to become sufficiently proximal to react, interact or physically touch. It should be appreciated; however, the resulting reaction product can be produced directly from a reaction between the added reagents or from an intermediate from one or more of the added reagents that can be produced in the reaction mixture.
The term “contacting” may include allowing two species to react, interact, or physically touch, wherein the two species may be a compound as described herein and a protein or enzyme. In some embodiments contacting includes allowing a compound described herein to interact with a protein or enzyme that is involved in a signaling pathway.
As defined herein, the term “activation”, “activate”, “activating” and the like in reference to a protein refers to conversion of a protein into a biologically active derivative from an initial inactive or deactivated state. The terms reference activation, or activating, sensitizing, or up-regulating signal transduction or enzymatic activity or the amount of a protein decreased in a disease.
As defined herein, the term “inhibition”, “inhibit”, “inhibiting” and the like in reference to a protein-inhibitor interaction means negatively affecting (e.g. decreasing) the activity or function of the protein relative to the activity or function of the protein in the absence of the inhibitor. In embodiments inhibition refers means negatively affecting (e.g. decreasing) the concentration or levels of the protein relative to the concentration or level of the protein in the absence of the inhibitor. In embodiments inhibition refers to reduction of a disease or symptoms of disease. In embodiments, inhibition refers to a reduction in the activity of a particular protein target. Thus, inhibition includes, at least in part, partially or totally blocking stimulation, decreasing, preventing, or delaying activation, or inactivating, desensitizing, or down-regulating signal transduction or enzymatic activity or the amount of a protein. In embodiments, inhibition refers to a reduction of activity of a target protein resulting from a direct interaction (e.g. an inhibitor binds to the target protein). In embodiments, inhibition refers to a reduction of activity of a target protein from an indirect interaction (e.g. an inhibitor binds to a protein that activates the target protein, thereby preventing target protein activation).
Integrins are transmembrane proteins that mediate interactions between adhesion molecules on adjacent cells and/or the extracellular matrix (ECM). Integrins have diverse roles in several biological processes including, for example, cell migration during development and wound healing, cell differentiation, and apoptosis. Integrins typically exist as heterodimers consisting of a subunits (about 120-170 kDa in size) and β subunits (about 90-100 kDa in size).
The terms “αvβ1” and “αvβ1 integrin” refer to an integrin comprised of αv subunit and a β1 subunit and is used according to its common, ordinary meaning. “αvβ1” refers to proteins of the same or similar names, homologs, isoforms, and functional fragments thereof, so long as such fragments retain αvβ1 integrin activity. The term includes any recombinant or naturally-occurring form of αvβ1, or an αvβ1 preprotein, or variants thereof that maintain αvβ1 activity (e.g. within at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% activity compared to wildtype αvβ1). In embodiments, αvβ1 has the amino acid sequence set forth in for example GI: 4504763.
Fibronectin is used according to its common, ordinary meaning and refers to proteins of the same or similar names, homologs, isoforms, and functional fragments thereof, so long as such fragments retain fibronectin activity. Fibronectin refers to glycoprotein dimers capable of binding integrins and mediating interactions between adhesion molecules in the ECM. The term includes any recombinant or naturally-occurring form of fibronectin, or a fibronectin preprotein, or variants thereof that maintain fibronectin activity (e.g. within at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% activity compared to wildtype fibronectin).
“TGF-β,” “TGFβ” or “transforming growth factor β” is used according to its common and ordinary meaning. TGFβ refers to proteins of the same or similar names, homologs, isoforms, and functional fragments thereof known to have TGFβ activity.
The term “expression” includes any step involved in the production of the polypeptide including, but not limited to, transcription, post-transcriptional modification, translation, post-translational modification, and secretion. Expression can be detected using conventional techniques for detecting protein (e.g., ELISA, Western blotting, flow cytometry, immunofluorescence, immunohistochemistry, etc.).
The terms “disease” or “condition” refer to a state of being or health status of a patient or subject capable of being treated with the compounds or methods provided herein. The disease may be fibrosis, such as for example, pulmonary fibrosis, liver fibrosis, skin fibrosis, cardiac fibrosis, or kidney fibrosis.
The terms “treating”, or “treatment” refers to any indicia of success in the therapy or amelioration of an injury, disease, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; improving a patient's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neuropsychiatric exams, and/or a psychiatric evaluation. The term “treating” and conjugations thereof, may include prevention of an injury, pathology, condition, or disease.
“Patient” or “subject in need thereof” refers to a living organism suffering from or prone to a disease or condition that can be treated by administration of a pharmaceutical composition as provided herein. Non-limiting examples include humans, other mammals, bovines, rats, mice, dogs, monkeys, goat, sheep, cows, deer, and other non-mammalian animals. In some embodiments, a patient is human.
A “effective amount” is an amount sufficient for a compound to accomplish a stated purpose relative to the absence of the compound (e.g. achieve the effect for which it is administered, treat a disease, reduce enzyme activity, increase enzyme activity, reduce a signaling pathway, or reduce one or more symptoms of a disease or condition). An example of an “effective amount” is an amount sufficient to contribute to the treatment, prevention, or reduction of a symptom or symptoms of a disease, which could also be referred to as a “therapeutically effective amount.” A “reduction” of a symptom or symptoms (and grammatical equivalents of this phrase) means decreasing of the severity or frequency of the symptom(s), or elimination of the symptom(s). A “prophylactically effective amount” of a drug is an amount of a drug that, when administered to a subject, will have the intended prophylactic effect, e.g., preventing or delaying the onset (or reoccurrence) of an injury, disease, pathology or condition, or reducing the likelihood of the onset (or reoccurrence) of an injury, disease, pathology, or condition, or their symptoms. The full prophylactic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a prophylactically effective amount may be administered in one or more administrations. An “activity decreasing amount,” as used herein, refers to an amount of antagonist required to decrease the activity of an enzyme relative to the absence of the antagonist. A “function disrupting amount,” as used herein, refers to the amount of antagonist required to disrupt the function of an enzyme or protein relative to the absence of the antagonist. The exact amounts will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins).
For any compound described herein, the therapeutically effective amount can be initially determined from cell culture assays. Target concentrations will be those concentrations of active compound(s) that are capable of achieving the methods described herein, as measured using the methods described herein or known in the art.
As is well known in the art, therapeutically effective amounts for use in humans can also be determined from animal models. For example, a dose for humans can be formulated to achieve a concentration that has been found to be effective in animals. The dosage in humans can be adjusted by monitoring compounds effectiveness and adjusting the dosage upwards or downwards, as described above. Adjusting the dose to achieve maximal efficacy in humans based on the methods described above and other methods is well within the capabilities of the ordinarily skilled artisan.
Dosages may be varied depending upon the requirements of the patient and the compound being employed. The dose administered to a patient, in the context of the present invention should be sufficient to effect a beneficial therapeutic response in the patient over time. The size of the dose also will be determined by the existence, nature, and extent of any adverse side-effects. Determination of the proper dosage for a particular situation is within the skill of the practitioner. Generally, treatment is initiated with smaller dosages which are less than the optimum dose of the compound. Thereafter, the dosage is increased by small increments until the optimum effect under circumstances is reached. Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.
As used herein, the term “administering” means oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intrathecal, intranasal or subcutaneous administration, or the implantation of a slow-release device, e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal) compatible with the preparation. Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc.
“Co-administer” it is meant that a composition described herein is administered at the same time, just prior to, or just after the administration of one or more additional therapies. The compounds of the invention can be administered alone or can be coadministered to the patient. Coadministration is meant to include simultaneous or sequential administration of the compounds individually or in combination (more than one compound). Thus, the preparations can also be combined, when desired, with other active substances (e.g. to reduce metabolic degradation). The compositions of the present invention can be delivered transdermally, by a topical route, or formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols.
A “cell” as used herein, refers to a cell carrying out metabolic or other function sufficient to preserve or replicate its genomic DNA. A cell can be identified by well-known methods in the art including, for example, presence of an intact membrane, staining by a particular dye, ability to produce progeny or, in the case of a gamete, ability to combine with a second gamete to produce a viable offspring. Cells may include prokaryotic and eukaroytic cells. Prokaryotic cells include but are not limited to bacteria. Eukaryotic cells include but are not limited to yeast cells and cells derived from plants and animals, for example mammalian, insect (e.g., spodoptera) and human cells. Cells may be useful when they are naturally nonadherent or have been treated not to adhere to surfaces, for example by trypsinization.
“Control” or “control experiment” is used in accordance with its plain ordinary meaning and refers to an experiment in which the subjects or reagents of the experiment are treated as in a parallel experiment except for omission of a procedure, reagent, or variable of the experiment. In some instances, the control is used as a standard of comparison in evaluating experimental effects. In some embodiments, a control is the measurement of the activity of a protein in the absence of a compound as described herein (including embodiments and examples).
As used herein “Fibrosis” refers to any disease or condition characterized by the formation of excess fibrous connective tissue. The formation of excess fibrous connective tissue may be in response to a reparative or reactive process. Fibrosis may be pulmonary fibrosis, liver fibrosis, myelofibrosis, skin fibrosis (e.g. nephrogenic systemic fibrosis and keloid fibrosis), mediastinal fibrosis, cardiac fibrosis, kidney fibrosis, stromal fibrosis, epidural fibrosis, or idiopathic fibrosis.

Fibrosis Models
Lung and liver fibrosis were induced as described previously [1, 2]. For CCl4—Induced liver fibrosis, mice were injected intraperitoneally (i.p.) with 1 ul/g body weight sterile CCl4 in a 1:3 ratio with olive oil or olive oil (control), twice weekly for six weeks. ALZET osmotic pumps (Durect, Cupertino, Calif.) were inserted after three weeks of treatment to deliver either c8 or the inactive control small molecule, C16, each dissolved in 50% DMSO (in sterile water) and administered at a dose of 70 mg/kg/day. Livers were harvested 24 hours after the last CCl4 injection. For bleomycin-induced lung fibrosis, 3 U/kg bleomycin (bleo) or water (control) was administered by direct airway intubation with a microsprayer (PennCentury, city). ALZET osmotic pumps were inserted 14 days after treatment, as above and lungs were harvested at 28 days [1].
Primary Cell Isolation
Primary mouse lung fibroblasts were isolated from 4-12 day old mice using a previously reported method, with minor modifications [3]. Mice lungs were removed, pooled together and digested in enzyme solution for total 1 h with removal of dispersed cells every 10 minutes. The enzyme solution consisted of Hanks buffered salt solution (HBSS, without Ca or Mg) with 0.3 mg/ml of type I collagenase (Sigma), and 0.5 mg/ml of trypsin (Sigma) in a shaking water bath maintained at 37° C. After each digestion interval, dispersed cells was passed through a sterile filter (70 um) into DMEM-Ham's F-12 media (Sigma), 10% fetal bovine serum, and undigested lung tissue placed in fresh enzyme solution. Once digestion was complete, erythrocytes were lysed at room temperature 10 min using red blood cell lysing buffer (Sigma). Then, the cells were pelleted by centrifugation, and cultured in DMEM medium with 10% fetal bovine serum, 1% penicillin/streptomycin in 100 mm tissue culture dishes. The nonadherent cells were aspirated, and the adherent fibroblast were grown in culture. Primary murine hepatic stellate cells were isolated and passaged as described previously [1]. Mouse liver was perfused through the inferior vena cava sequentially with liver perfusion media (Invitrogen). 0.3% pronase (Roche) and 0.02% collagenase (Sigma). The liver was excised and minced with scissors and further digested in 0.044% pronase and 0.008% DNAse (Roche). The cell suspension was shaken (200-250 rpm) at 37° C. for 10 minutes and strained through a sterile filter (70 μm). To remove hepatocytes the cell suspension was centrifuged at 90×g for 2 minutes, the supernatant collected, DNAse added and this procedure was repeated twice. The supernatant was centrifuged at 700×g for 7 minutes to collect the non-parenchymal cell fraction. Collected cells were re-suspended in 10 ml of complete DMEM (10% fetal bovine serum, 1% penicillin/streptomycin) and allowed to differentiate in culture into myofibroblasts before use.
Hydroxyproline Assay
Mouse lung, liver, and kidney tissue was homogenized with trichloroacetic acid and incubated overnight at 110° C. in HCl. Samples were reconstituted in water, and hydroxyproline content was measured using the chloramine T assay [4].
Immunoprecipitation and Western Blotting
Cells were lysed in RIPA buffer (50 mM Tris-HCL, ph 7.4, 10 mM MgCl2, 125 mM NaCl, 2% NP-40), cell lysates were centrifuged at 14,000 rpm for ten minutes at 4° C. and the supernatant collected. 10 μg of anti-av antibody (for human fibroblast L230, and for murine fibroblast RMV-7, a kind gift from Dr. H Yagita, Juntendo University, Japan) was added to the supernatant and this was rotated at 4° C. for two hours, followed by the addition of 30 μl of prewashed protein G sepharose slurry (GE Healthcare) for one hour at 4° C. The beads were washed three times with PBS/protease inhibitor mixture, and once with PBS only. Laemmli sample buffer was added and the samples were boiled for five minutes followed by SDS-PAGE and western blotting using the following antibodies: αv integrin 611012, 1:500 (BD Biosciences), β1integrin 04-11-09, 1:500 (Millipore).
TGFB Activation Assay
Test cells were plated at 50K cells/well in 96-well plates together with mink lung epithelial cells expressing firefly luciferase downstream of the TGFβ sensitive portion of the plasminogen activator inhibitor 1 promoter (15K cells/well) [1]. Cells were co-cultured for 16 hours and TGFβ activity was calculated by measurement of luminescencein the presence and absence of TGFβ-blocking antibody, 1D11.
Integrin-Specific Adhesion Assays
The effects of c8 and c16 on cell adhesion mediated by α5β1, α8β1, αvβ1, αvβ3, αvβ5, αvβ6, and αvβ8 were measured using pairs of cell lines and ligands selected to isolate the effect of each individual integrin. For α5β1 we utilized the colon carcinoma cell line, SW480, plated on 0.3 μg/ml fibronectin, for α8β1, we utilized SW480 cells transfected with human α8 adhering to 1 μg/ml recombinant TGFβ1 LAP [5], for αvβ1 we used Chinese Hamster Ovary Cells (CHO cells) transfected with human αv adhering to 0.3 μg/ml fibronectin [6], for αvβ3 we used SW480 cells transfected with human β3, for αvβ5 we used wild type SW480 cells adhering to 0.1 μg/ml vitronectin. For αvβ6 we used SW480 cells transfected with human (36 adhering to 0.01 μg/ml recombinant human TGFβ1 LAP. For αvβ8 we used glioma cell line (SNB19) expressing β8 adhering to 1 μg/ml recombinant human TGFβ1 LAP. In every case, we confirmed that adhesion could be inhibited by blocking antibodies to the relevant integrin (complex-specific blocking antibodies in all cases except αvβ1 for which we showed equivalent effects of blocking αv and β1). Cells were resuspended in DMEM for 30 min at 4° C. with 10-fold dilutions of c8 with a starting concentration of 10 μM. Each sample was then added to triplicate wells of a 96-well plate which had been coated overnight at 4° C. with the relevant ligand, washed, blocked by 1 hr incubation with 1% BSA, and washed again. Cells were allowed to attach for 30-60 min at 37° C. After incubation, non-adherent cells were removed by discarding the media and spinning the plate top-side down at 500 rpm for 5 minutes. Cells were then fixed and stained with 40 ul of 0.5% Crystal violet, 1% Formaldehyde, 20% Methanol for 30 minutes and lysed with 2% Trition-X. Absorbance was measured at 595 nm in a Microplate reader. For all assays, concentration-response curves were constructed by non-linear regression analysis and IC50 values were calculated using GraphPad Prism software.
Tissue Staining
Paraffin-embedded sections were processed as described previously [1]. 5 μM sections were stained Hematoxylin and Eosin or with picrosirius red. Pictures were taken from random fields from each section, at a final magnification of 10×. Staining area was calculated by pixel counting with NIH image J. For florescence microscopy, fixed livers and lungs were transferred to 30% sucrose in PBS overnight, embedded in OCT, then cryosectioned at 5 μm. Cryosections were permeabilized and blocked with 0.3% Triton X-100 and 3% BSA in PBS. Sections were incubated with primary antibodies (rabbit anti-phospho-Smad3 Epitomics, 1880-1, 1:100; rat anti-PDGFRb eBiosciences 14-1402, 1:100) overnight at 4° C., then with fluorophore-conjugated secondary antibodies (Invitrogen). Confocal imaging was performed on a Zeiss LSMS Pascal microscope. Phospho-Smad immunofluorescent staining was quantified as described [7].
Statistics
All data are presented as mean±S.E.M unless otherwise noted. Statistical significance was calculated using a one way analysis of variance and Tukey test to determine post-hoc significance between individual groups. p-values were defined using Student's t test for paired comparisons. Differences with a P value of less than 0.05 were considered statistically significant.
Example 3Fibrosis is a pathologic process, characterized by overproduction of extracellular matrix (ECM) as a response to tissue injury. Nearly 45% of all deaths in the developed world can be attributed to some type of chronic fibroproliferative disease (1, 2). Despite their high prevalence, current therapeutic options for fibrotic diseases are quite limited to elimination of triggering stimuli and organ transplantation. No effective agent exists that can directly halt the disease progression at the cellular level, which represents a major unmet medical need. However, our understanding of fibrogenesis has rapidly grown for the last two decades to shed light on new therapeutic targets in the vast complexity of fibrogenesis pathways (3-10). Cellular damage triggers the recruitment of inflammatory cells, which in turn secrete cytokines that induce the accumulation of activated fibroblasts. These so-called myofibroblasts are key executors of fibrosis as they are the main producers of collagen and other ECM. The origin of myofibroblasts is still under debate (11) but it is generally agreed that transforming growth factor beta (TGFβ) plays a role as a central pro-fibrotic factor in fibroblast activation and differentiation to myofibroblasts. TGFβ is secreted as a latent form and requires integrin binding to be fully active, which suggests that inhibition of integrin binding to the latent TGFβ complex is a promising therapeutic target.
Integrins are a family of transmembrane receptors consisting of two non-covalently bound a and 13 subunits (12, 13). In the process of fibroblast activation, there is a positive feedback loop between TGFβ and αv integrins (14, 15). In fact, epithelium-derived αvβ6 integrin is known to directly activate TGFβ in pulmonary fibrosis, and an αvβ6 blocking antibody is currently in phase II clinical trials for pulmonary fibrosis (16-18). In contrast to αvβ6 which is restricted to the epithelium, other αv integrins (αvβ1, αvβ3, αvβ5 and αvβ8) are expressed in myofibroblasts in many organs. Despite the fact that myofibroblasts are responsible for the majority of ECM production, little is known concerning the role of these av integrins in fibrosis. We produced mice lacking all αv integrins on myofibroblasts (αv f/f PDGFRβ Cre+) and found they are protected from CC14-induced liver fibrosis. These mice are also protected from renal fibrosis induced by unilateral ureteral obstruction and pulmonary fibrosis induced by bleomycin. However, global deletion of αvβ3 or αvβ5 or fibroblast-specific deletion of αvβ8 (mice with global β8 deletion die in utero) did not protect against hepatic fibrosis. These results strongly suggest that hepatic protection is mostly due to the loss of αvβ1 integrin. However, experimental validation to identify the critical role of αvβ1 integrin in fibrosis poses a very challenging problem: it is not possible to study the in vivo role of αvβ1 using knockout mice since mice lacking β1 on myofibroblasts do not survive. Effective blocking monoclonal antibodies against αvβ1 integrin are not available, either. Thus pharmacological modulation of αvβ1 integrin by small molecules is a very attractive route to test the role of αvβ1 integrin in tissue fibrosis.
Given that 16 of 24 integrins contain either an αv chain or β1 chain, it is important to develop potent, selective αvβ1 integrin inhibitors. These molecules can be used to probe the role of αvβ1 integrin in tissue fibrosis as well as other diseases. In preliminary studies we prepared a small series of αvβ1 antagonists by combining fragments known to target the av and β1 subunits based on our earlier published studies (19, 20). So far, we have identified one compound 8 that inhibits cell adhesion by αvβ1 integrin in a highly selective manner at <100 pM concentration.
We have found that compound 8 inhibits TGFβ activation by cultured liver myofibroblasts, whereas antibodies that block αvβ3, αvβ5 and αvβ8 do not. Encouraged by these data, we will conduct more in-depth studies of cell adhesion inhibition mediate by all RGD-binding integrins. We will also inititate more extensive structure-activity relationships (SAR) to obtain a panel of small molecules with the greatest potency and selectivity against αvβ1. The best compound thus identified will be tested in cell-based assays as well as a mouse liver fibrosis model as described below. In addition, large-scale preparation will be pursued to ensure a sufficient supply for animal studies.
αvβ1 integrin inhibition is effective in cell adhesion assay/mouse liver fibrosis model: Inhibitors were tested in cell adhesion assay to test their potency/selectivity. A panel of cell lines and integrin ligands were developed to allow rapid examination of potency and specificity of inhibitors against all 8 integrins that recognize RGD sequences in ligands. A subset of these was used to generate the very encouraging data about 8 shown above. These cell lines were used to calculate IC50 concentrations for each inhibitor synthesized to rapidly generate structure activity information to drive subsequent modification and synthesis. Inhibitors were evaluated for showing better potency/selectivity in CCl4-induced liver fibrosis. A general inhibitor of αv integrins can reverse fibrosis in this model when administered as a continuous subcutaneous infusion (from Alzet pumps) beginning 3 weeks after CCl4 initiation. However, global inhibition of all αv integrins is likely to cause unacceptable side effects. We will therefore take a similar approach for each of the most promising αvβ1 inhibitors identified in aim 1, using Alzet pumps to administer the inhibitor, or an inactive relative, to groups of 10 mice treated with either vehicle or CCl4 3× weekly for 6 weeks. As above, pumps will be inserted after 3 weeks of CC14 treatment. Once we find small molecules that are effective, each will be further tested in the UUO model of renal fibrosis and the bleomycin model of pulmonary fibrosis. Again we will examine therapeutic rather than prophylactic efficacy by beginning treatment in each model after the onset of fibrosis.
