  • Patent number: 7199147
    Abstract: A compound represented by the formula (1): wherein R1—X— indicates that 1 to 4 R1—X— groups are present which may be the same or different, the ring A is a saturated or unsaturated 5-membered heterocyclic ring, X is a single bond, a group represented by the formula: —N(R3)—, —O— or —S—, or the like. R1 is a hydrogen atom, a halogen atom, a nitro group, a carboxyl group, a substituted or unsubstituted alkyl group, or the like, R2 is a hydrogen atom, a halogen atom, a nitro group, a carboxyl group, a substituted or unsubstituted alkyl group, or the like, and R3 is a hydrogen atom, a substituted or unsubstituted alkyl group, or the like; a prodrug of said compound, or a pharmaceutically acceptable salt of said compound or prodrug is a useful compound as a therapeutic agent for diseases for which Rho kinase is responsible.

  • Publication number: 20050182040
    Abstract: A compound represented by formula (1): wherein X is a single bond or a substituted or unsubstituted lower alkylene group; Z is a saturated or unsaturated monocyclic hydrocarbon ring group or the like; and each of R1, R2, R3 and R4, which may be the same or different, is a hydrogen atom, a halogen atom, a nitro group, a cyano group, a carboxyl group, a substituted or unsubstituted alkyl group, or the like, a prodrug of said compound, or a pharmaceutically acceptable salt of said compound or prodrug has inhibitory effect on Rho kinase and hence is useful for treating diseases which are such that morbidity due to them is expected to be improved by inhibition of Rho kinase and secondary effects such as inhibition of the Na+/H+ exchange transport system caused by the Rho kinase inhibition, for example, hypertension.

  • Publication number: 20040152132
    Abstract: The invention provides solid support synthetic methods for producing combinatorial libraries of modulators of LXRs. The combinatorial libraries thus produced are useful both as diagnostic indicators of LXR&agr; function and as pharmacologically active agents. The combinatorial libraries find particular use in the treatment of disease states associated with cholesterol metabolism, particularly atherosclerosis and hypercholesterolemia.
