The structure-activity relationship of Rho kinase inhibitors bearing an isoquinoline scaffold was studied. N-(1-Benzyl-3-pyrrolidyl)-N-(5-isoquinolyl)amine analogues were optimized with respect to their inhibitory potencies for the enzyme and for chemotaxis. The potent analogues were further evaluated by an ex vivo test in which the selected compounds were orally administered to rats, and the Rho kinase inhibitory potency observed in the rat serum was evaluated 3 h after the administration. Compound 23g showed a high level of Rho kinase inhibitory activity in the rat serum and was stable in an in vitro metabolic test using a microsomal cytochrome preparation. The (R)-isomer of 23g displayed a higher level of inhibitory potency than the (S)-isomer in a cell-free kinase assay and in the cell migration assay (IC50ENZ = 25 nM and IC50MCP = 1 μ M). The (R)-isomer successfully inhibited the phosphorylation of MBS (myosin-binding subunit) in cells.

An objective of the present invention is to provide compounds having Rho kinase inhibitory activity and useful for the treatment of diseases mediated by Rho kinase. The compounds according to the present invention are those represented by formula (I) or pharmaceutically acceptable salts or solvates thereof: wherein Q represents phenyl, pyridyl, pyrrolyl, thienyl, or furyl; these groups are optionally substituted by one or two halogens or alkyl, nitro, or amino groups; and p is 2 or 3.
