[0001] This application claims the benefit of U.S. Provisional Application No. 60/365,314 filed Mar. 18, 2002, the disclosure of which is incorporated herein by reference thereto.
FIELD OF THE INVENTION[0002] This invention relates to the treatment of chemokine mediated diseases using CXC chemokine receptor antagonists in combination (or association) with other pharmaceutical compounds.
BACKGROUND OF THE INVENTION[0003] Chemokines are chemotactic cytokines that are released by a wide variety of cells to attract macrophages, T-cells, eosinophils, basophils, neutrophils and endothelial cells to sites of inflammation and tumor growth. There are two main classes of chemokines, the CXC-chemokines and the CC— chemokines. The class depends on whether the first two cysteines are separated by a single amino acid (CXC-chemokines) or are adjacent (CC-chemokines). The CXC-chemokines include interleukin-8 (IL-8), neutrophil-activating protein-1 (NAP-1), neutrophil-activating protein-2 (NAP-2), GRO&agr;, GRO&bgr;, GRO&ggr;, ENA-78, GCP-2, IP-10, MIG and PF4. CC chemokines include RANTES, MIP-1&agr;, MIP-2&bgr;, monocyte chemotactic protein-1 (MCP-1), MCP-2, MCP-3 and eotaxin. Individual members of the chemokine families are known to be bound by at least one chemokine receptor, with CXC-chemokines generally bound by members of the CXCR class of receptors, and CC-chemokines by members of the CCR class of receptors. For example, IL-8 is bound by the CXCR-1 and CXCR-2 receptors.
[0004] Since CXC-chemokines promote the accumulation and activation of neutrophils, these chemokines have been implicated in a wide range of acute and chronic inflammatory disorders including psoriasis and rheumatoid arthritis. Baggiolini et al., FEBS Left. 307, 97 (1992); Miller et al., Crit. Rev. Immunol. 12, 17 (1992); Oppenheim et al., Annu. Fev. Immunol. 9, 617 (1991); Seitz et al., J. Clin. Invest. 87, 463 (1991); Miller et al., Am. Rev. Respir. Dis. 146, 427 (1992); Donnely et al., Lancet 341,643(1993).
[0005] Hence, the CXC-chemokine receptors represent promising targets for the development of novel anti-inflammatory agents.
[0006] There remains a need for an improved method of treating CXC-chemokine mediated diseases. For example, conditions associated with an increase in IL-8 production (which is responsible for chemotaxis of neutrophil and T-cell subsets into the inflammatory site) would benefit by an improved method that inhibits IL-8 receptor binding. Such an improved method is provided by this invention.

[0428] A most preferred group of compounds of formula (I) useful in the methods of this invention include: 167 168 169 170 171
[0429] Certain compounds of formula (I) may exist in different stereoisomeric forms (e.g., enantiomers, diastereoisomers and atropisomers). The invention contemplates all such stereoisomers both in pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional methods.
[0430] Certain compounds will be acidic in nature, e.g. those compounds which possess a carboxyl or phenolic hydroxyl group. These compounds may form pharmaceutically acceptable salts. Examples of such salts may include sodium, potassium, calcium, aluminum, gold and silver salts. Also contemplated are salts formed with pharmaceutically acceptable amines such as ammonia, alkyl amines, hydroxyalkylamines, N-methylglucamine and the like.
[0431] Certain basic compounds also form pharmaceutically acceptable salts, e.g., acid addition salts. For example, the pyrido-nitrogen atoms may form salts with strong acid, while compounds having basic substituents such as amino groups also form salts with weaker acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those skilled in the art. The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt in the conventional manner. The free base forms may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous NaOH, potassium carbonate, ammonia and sodium bicarbonate. The free base forms differ from their respective salt forms somewhat in certain physical properties, such as solubility in polar solvents, but the acid and base salts are otherwise equivalent to their respective free base forms for purposes of the invention.
[0432] All such acid and base salts are intended to be pharmaceutically acceptable salts within the scope of the invention and all acid and base salts are considered equivalent to the free forms of the corresponding compounds for purposes of the invention.
[0433] Compounds of formula (I) can exist in unsolvated and solvated forms, including hydrated forms. In general, the solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like, are equivalent to the unsolvated forms for the purposes of this invention.
[0434] This invention also includes Prodrugs of the novel compounds of this invention, and of the compounds of formula (I) useful in the methods of this invention. The term “prodrug,” as used herein, represents compounds which are rapidly transformed in vivo to the parent compound of the above formula, for example, by hydrolysis in blood. A thorough discussion is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series, and in Edward B. Roche, ed., Bioreversible Carriers in Drug Design, American Pharmaceutical Association and Pergamon Press, 1987, both of which are incorporated herein by reference.
[0435] For preparing pharmaceutical compositions from the compounds of formula (I), inert, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may be comprised of from about 5 to about 95 percent active ingredient. Suitable solid carriers are known in the art, e.g., magnesium carbonate, magnesium stearate, talc, sugar or lactose. Tablets, powders, cachets and capsules can be used as solid dosage forms suitable for oral administration. Examples of pharmaceutically acceptable carriers and methods of manufacture for various compositions may be found in A. Gennaro (ed.), Remington: The Science and Practice of Pharmacy, 20th Edition, (2000), Lippincott Williams & Wilkins, Baltimore, Md.
[0436] Liquid form preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injection or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.
[0437] Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier, such as an inert compressed gas, e.g. nitrogen.
[0438] Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.
[0439] The compounds of formula (I) may also be deliverable transdermally. The transdermal composition can take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.
[0440] Preferably the compound of formula (I) is administered orally.
[0441] Preferably, the pharmaceutical preparation is in a unit dosage form. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose.
[0442] The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.01 mg to about 1000 mg, preferably from about 0.01 mg to about 750 mg, more preferably from about 0.01 mg to about 500 mg, and most preferably from about 0.01 mg to about 250 mg, according to the particular application.
[0443] The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage regimen for a particular situation is within the skill of the art. For convenience, the total dosage may be divided and administered in portions during the day as required.
[0444] The amount and frequency of administration of the compounds of formula (I) and/or the pharmaceutically acceptable salts thereof will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. A typical recommended daily dosage regimen for oral administration can range from about 0.04 mg/day to about 4000 mg/day, in two to four divided doses.
[0445] The compounds used in combination with the compounds of formula (I) can be administered in their normally prescribed amounts as know by the skilled clinician (see, for example, the Physicians' Desk Reference, 56th edition, 2002, published by Medical Economics company, Inc. at Montvale, NJ 07645-1742, the disclosure of which is incorporated herein by reference thereto). The amount and frequency of administration of the compounds used in combination with the compounds of formula (I) will be regulated according to the judgment of the attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated.
Biological Assays[0446] The compounds of formula (I) are useful in the treatment of CXC-chemokine mediated conditions and diseases. This utility is manifested in their ability to inhibit IL8 and GRO-&agr; chemokine as demonstrated by the following in vitro assays.

[0466] Carrageenan-Induced Rat Paw Edema Model
[0467] Carrageenan (0.05 ml of an 1% solution in saline) was injected into one hindpaw of male Sprague-Dawley rats. Paw volumes (ml) were measured by a water displacement plethysmometer prior to and 3 h after the injection of carrageenan. The increase in paw volume that occurred between the two timepoints was determined for each group. Rats received Compound A: 172
[0468] (see Example 405 of WO 02/083624) or standard drugs in methylcellulose vehicle by the oral route, 1 hr before carrageenan injection. The percentage by which the edematous response was inhibited was calculated by comparing the increase in paw edema of drug-treated rats to that of vehicle-treated controls. To determine neutrophil accumulation in the paws, rats were sacrificed at 3 hrs and myeloperoxidase (MPO) activity was measured from inflammatory fluid expressed from the hindpaw using a calorimetric assay (Bradley et al., 1982). PGE2 production in the hindpaw was assessed by ELISA (R&D Systems, Minneapolis, Minn.).
[0469] Combination studies were performed with Compound A and the following standard anti-inflammatory agents—the non-selective anti-inflammatory drug indomethacin, and the steroid betamethasone. The combination of suboptimal doses of compound A at 1 mg/kg (20% inhibition) and indomethacin at 0.5 mg/kg (0% inhibition) caused a significant 41% reduction of paw edema, suggesting that this combination results in greater efficacy than either agent alone. This combination did not cause a further reduction in MPO activity in the hindpaw compared to compound A alone (Compound A=67% inhibition; indomethacin=−58% inhibition; combination=55% inhibition). The combination of suboptimal doses of Compound A at 1 mg/kg and betamethasone at 0.05 mg/kg (32% inhibition) also demonstrated greater efficacy in inhibiting edema (61% inhibition). An additive inhibition of paw PGE2 levels was also observed (31% inhibition by either betamethasone or Compound A alone, versus 78% inhibition with the combination).
[0470] Streptococcal Cell Wall-Induced Mouse Knee Swelling Model
[0471] The method described by Lubberts et al, 1998 was used for these studies, with some modifications. Female 8-12 week old C57BL/6J animals were fasted overnight and dosed orally with Compound A, indomethacin, or a combination of these agents suspended in methylcellulose one hour prior to a single intra-articular injection of 6 &mgr;l containing 25 &mgr;g of bacterial SCW (4.32 mg/ml rhammose; Lee Laboratories, Grayson, Ga.) in saline into the right knee joint. The left knee joint received an injection of 6 &mgr;l of saline at the same time. In other experiments, a neutralizing rat anti-mouse TNF&agr; antibody or matched rat IgG isotype control was administered intraperitoneally two hours prior to SCW injection and Compound A or methylcellulose vehicle was orally administered one hour prior to SCW injection. Knee swelling measurements were performed 2 hours after SCW injection using a dial-gauge caliper (Starret, Athol, Mass.) by measuring the difference in swelling between the right and left knee joints. Patellar organ cultures for assessment of synovial cytokine and chemokine and prostaglandin levels were prepared at 2 hours after SCW injection and established as described (Lubberts et al, 1998), using ELISA kits obtained from R&D Systems (Minneapolis, Minn.). Statistical analysis was performed using the Student's t-test, with p<0.05 considered to be indicative of statistical significant differences between groups.
[0472] Combination therapy with Compound A (10 mg/kg=46% inhibition; 25 mg/kg=70% inhibition) and indomethacin (2 mg/kg=42% inhibition) resulted in significantly greater reduction of knee swelling compared to either agent alone in all instances. Thus, the combination of Compound A at 10 mg/kg with indomethacin resulted in a 74% inhibition of the response, while Compound A at 25 mg/kg in combination with indomethacin led to a 93% inhibition of the swelling response. Compound A administered alone significantly inhibited IL-1&bgr; production by ex vivo patellar organ culture (49% inhibition at 10 mg/kg; 64% inhibition at 25 mg/kg) while indomethacin treatment resulted in a 11% inhibition. Combination treatment resulted in a 71% (10 mg/kg Compound A+indomethacin) and 57% inhibition (25 mg/kg Compound A+indomethacin) of IL-1&bgr; production, consistent with the concept that the effect on IL-1&bgr; was attributable to the pharmacological action of Compound A. In comparison, the effect of combination therapy on PGE2 levels (86% and 85% inhibition, respectively) in patellar organ culture was accounted for by the activity of indomethacin alone (89% inhibition) while Compound A alone had mild activity (34-40% inhibition at 10-25 mg/kg).

[0475] Compounds of formula (I) may be produced by processes known to those skilled in the art, in the following reaction schemes, and in the preparations and examples below. Specific procedures for the preparation of many of the compounds of formula (I) may be found in in WO 02/076926 published Oct. 3, 2002, and WO 02/083624 published Oct. 24, 2002.
[0476] A general procedure for the preparation of compounds of formula (I) is as follows: 173 174
[0477] Scheme 1
[0478] An amine is condensed (Step A) with a nitrosalicylic acid under standard coupling conditions and the resulting nitrobenzamide is reduced (Step B) under hydrogen atmosphere in the presence of a suitable catalyst. The remaining partner required for the synthesis of the final target is prepared by condensing an aryl amine with the commercially available diethylsquarate to give the aminoethoxysquarate product. Subsequent condensation of this intermediate with the aminobenzamide prepared earlier provides the desired chemokine antagonist (Scheme 1).
[0479] Scheme 2
[0480] Alternatively, the aminobenzamide of Scheme 1 is first condensed with commercially available diethylsquarate to give an alternate monoethoxy intermediate. Condensation of this intermediate with an amine gives the desired chemokine antagonist. 175 176
[0481] Scheme 3
[0482] Benztriazole compounds of Formula (I) are prepared by stirring nitrophenylenediamines with sodium nitrite in acetic acid at 60° C. to afford the nitrobenzotriazole intermediate (Scheme 3). Reduction of the nitro group in the presence of palladium catalyst and hydrogen atmosphere provides the amine compound. Subsequent condensation of this intermediate with the aminooethoxysquarate prepared earlier (Scheme 1) provides the desired chemokine antagonist.
[0483] Scheme 4
[0484] Condensation of nitrophenylenediamines with anhydrides or activated acids at reflux (Scheme 4) affords benzimidazole intermediates which after reduction with hydrogen gas and palladium catalyst and condensation with the aminoethoxysquarate previously prepared (Scheme 1) affords benzimidazole chemokine antagonists. 177 178
[0485] Scheme 5
[0486] Indazole structures of Formula (I) can be prepared according to Scheme 5 by reduction of nitroindazole A (J. Am. Chem Soc. 1943, 65, 1804-1805) to give aminoindazole B and subsequent condensation with the aminoethoxysquarate prepared earlier (Scheme 1).
[0487] Scheme 6
[0488] Indole structures of Formula (I) can be prepared according to Scheme 6 by reduction of nitroindole A (J. Med. Chem. 1995, 38, 1942-1954) to give aminoindole B and subsequent condensation with the aminoethoxysquarate prepared earlier (Scheme 1).
[0489] The invention disclosed herein is exemplified by the following preparations and examples which should not be construed to limit the scope of the disclosure. Alternative mechanistic pathways and analogous structures may be apparent to those skilled in the art.
PREPARATIVE EXAMPLES 13.17A-13.17B[0490] Following the procedure set forth in Preparative Example 13.13 in WO 02/083624, but using the prepared or commercially available aldehydes, the optically pure amine products in the Table below were obtained. 1 Prep Ex.

PREPARATIVE EXAMPLE 13.29[0491] 185
[0492] Step A
[0493] To a solution of 3-methoxythiophene (3 g) in dichloromethane (175 mL) at −78° C. was added chlorosulfonic acid (8.5 mL) dropwise. The mixture was stirred for 15 min at −78° C. and 1.5 h at room temp. Afterwards, the mixture was poured carefully into crushed ice, and extracted with dichloromethane. The extracts were washed with brine, dried over magnesium sulfate, filtered through a 1-in silica gel pad.
[0494] The filtrate was concentrated in vacuo to give the desired compound (4.2 g).
[0495] Step B
[0496] The product from Step A above (4.5 g) was dissolved in dichloromethane (140 mL) and added with triethylamine (8.8 mL) followed by diethyl amine in THF (2M, 21 mL). The resulting mixture was stirred at room temperature overnight. The mixture was washed with brine and saturated bicarbonate (aq) and brine again, dried over sodium sulfate, filtered through a 1-in silica gel pad. The filtrate was concentrated in vacuo to give the desired compound (4.4 g).
[0497] Step C
[0498] The product from Step B above (4.3 g) was dissolved in dichloromethane (125 mL) and cooled in a −78° C. bath. A solution of boron tribromide (1.0 M in dichloromethane, 24.3 mL) was added. The mixture was stirred for 4 h while the temperature was increased slowly from −78° C. to 10° C. H2O was added, the two layers were separated, and the aqueous layer was extracted with dichloro-methane.
[0499] The combined organic layer and extracts were washed with brine, dried over magnesium sulfate, filtered, and concentrated in vacuo to give 3.96 g of the desired hydroxy-compound.
[0500] Step D
[0501] The product from step C above (3.96 g) was dissolved in 125 mL of dichloromethane, and added with potassium carbonate (6.6 g) followed by bromine (2 mL). The mixture was stirred for 5 h at room temperature, quenched with 100 mL of H2O. The aqueous mixture was addjusted to pH ˜5 using a 0.5N hydrogen chloride aqueous solution, and extracted with dichloromethane. The extracts were washed with a 10% Na2S2O3 aqueous solution and brine, dried over sodium sulfate, and filtered through a celite pad. The filtrate was concentrated in vacuo to afford 4.2 g of the desired bromo-compound.
[0502] Step E
[0503] The product from Step D (4.2 g) was dissolved in 100 mL of acetone and added with potassium carbonate (10 g) followed by iodomethane (9 mL). The mixture was heated to reflux and continued for 3.5 h. After cooled to room temperature, the mixture was filtered through a Celite pad.
