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.
由式(1)代表的化合物:
其中 X 是单键或取代或未取代的低级亚烷基; Z 是饱和或不饱和的单环烃环基或类似物;以及 R1、R2、R3 和 R4(可以相同或不同)中的每一个是氢原子、卤素原子、硝基、氰基、羧基、取代或未取代的烷基或类似物,所述化合物的原药、或所述化合物或原药的药学上可接受的盐对 Rho 激酶有抑制作用,因此可用于治疗因抑制 Rho 激酶而发病率有望得到改善的疾病,以及因抑制 Rho 激酶而导致 Na+/H+ 交换转运系统受到抑制等副作用的疾病,例如高血压。
