Abstract: This invention provides compounds of formula I where Ar1 is a 5- to 10-member mono- or bicyclic aromatic group, optionally substituted; where the —NR3R4 group is situated ortho to the NHC(?X) group; n=1 or 2; X?O or S; Y is O or S; and q=1 or 0. The invention also provides pharmaceutical compositions comprising compounds of formula I and/or salts, esters, and prodrugs thereof. These compounds modulate the activation and inactivation of potassium channels. The compounds are useful for the treatment and prevention of diseases and disorders—such as seizure disorders—which are affected by modulation of potassium ion channels.

Abstract: This invention provides compounds of formula I where the dashed line represents an optional double bond; where R1 is phenyl, naphthyl, pyridyl, pyrimidyl, pyrrolyl, imidazolyl, pyrazyl, furyl, thienyl, oxazolyl, isoxazolyl, thiazolyl, or isothiazolyl, optionally substituted, and other substituents are defined herein. Such compounds are potassium channel modulators.

Abstract: This invention provides a compound of formula IA where X=0 or S; Y is 0 or S; q=1 or 0; and other substituents are defined herein. Such compounds can affect the opening of, or otherwise modulate, voltage-gated potassium channels. Such compounds useful for the treatment and prevention of diseases and disorders which are affected by activation or modulation of potassium ion channels. One such condition is seizure disorders.

Abstract: A modified release pharmaceutical formulation includes about 30-70% N-(2-amino-4-(fluorobenzylamino)-phenyl)carbamic acid ethyl ester (retigabine), or a pharmaceutically acceptable salt, solvate or hydrate thereof, about 5-30% of a drug delivery matrix including hydroxypropylmethylcellulose (HPMC), about 1.0-10% of an anionic surfactant, and an enteric polymer. The pharmaceutical formulation produces a sustained plasma concentration of retigabine following administration to a subject for 4-20 hours longer than the time required for in vitro release of 80% of retigabine. A formulation includes about 30-70% N-(2-amino-4-(fluorobenzylamino)-phenyl)carbamic acid ethyl ester (retigabine), or a pharmaceutically acceptable salt, solvate or hydrate thereof, about 5-30% of a drug delivery matrix, and an agent for retarding release in the gastric environment. The plasma concentration vs. time profile of this formulation is substantially flat over an extended period lasting for about 4 hours to about 36 hours.

Abstract: This invention provides potassium channel modulators which are compounds of formula I where at least one of W and Z is N; where the moiety is one of Groups A or B below A where Ar is a 1,2-fused, six membered ring aromatic group, bearing substituents R1 and R2 as defined below, and containing zero or one ring nitrogen atom; and where other substituents are defined herein. The invention also provides a composition comprising a pharmaceutically acceptable carrier and at least one of the following: i) a pharmaceutically effective amount of a compound of formula I and ii) a pharmaceutically acceptable salt, ester, or prodrug thereof. The invention also provides a method of preventing or treating a disease or disorder which is affected by activities of potassium channels, comprising administering to a patient in need thereof a therapeutically effective amount of a compound of formula I or a salt, ester, or prodrug thereof.

Abstract: This invention is directed to compounds of formula I, where G is —O—, —S—, —C(g1)(g2)-, or —NH—, and n=1, 2, or 3. Such compounds modulate potassium channels. The compounds are useful for the treatment and prevention of diseases and disorders which are affected by modulation of potassium ion channels. One such condition is seizure disorders.

Abstract: The present invention provides methods for treating individuals having a hepatitis C virus (HCV) infection, which individuals have failed to respond to therapy with an IFN-? other than consensus interferon (CIFN), or who, following cessation of therapy with an IFN-? other than CIFN, have suffered relaspe. The methods generally involve a treatment regimen comprising administering a first dosing regimen of CIFN, followed by a second dosing regimen of CIFN. Ribavirin is administered with at least the second dosing regimen.

Abstract: Novel heterocyclic aromatic compounds are disclosed. The novel compounds or pharmaceutically acceptable esters or salts thereof may be used in pharmaceutical compositions, and such compositions may be used to treat an infection, an infestation, a neoplasm, or an autoimmune disease. The novel compounds may also be used to modulate aspects of the immune system, including modulation of Type 1 and Type 2 activity.

Abstract: A number of modified nucleosides are disclosed composed of modified sugar moieties which contain substituents at C1 and C4 positions, or branched substituents at C3 and C5 positions of deoxyribose or ribose. Each nucleoside is converted to or properly protected and then converted to the corresponding phosphoramidites. These phosphoramidites are used to assemble oligonucleotides in which there is at least one of the forenoted nucleosides. These sugar modified oligonucleotides have the potential to be used as antisense therapies since they are expected to enhance nuclease resistance and cellular uptake while they maintain sequence-specificity and affinity to nucleic acid targets in vitro or in vivo.
