The present invention provides an amino compound represented by Formula: ##STR1## wherein X is CH.sub.2 NH or CONH, Y is CH.sub.2 NH or CONH with the proviso that X and Y are not CONH at the same time; Z is CH.dbd.C(R.sup.4)R.sup.5, CH.sub.2 CH(R.sup.4)R.sup.5 or an alkoxycarbonyl group, R.sup.1 is a hydrogen atom; a lower alkyl group, a cycloalkyl group, a cycloalkyl-substituted alkyl group, an aralkyl group or an aryl group, each group of which is substituted or unsubstituted, R.sup.2 and R.sup.3 are each independently a lower alkyl group or an aralkyl group, each group of which is substituted or unsubstituted, and R.sup.4 and R.sup.5 are each independently a hydrogen atom; an alkyl group, an aralkyl group, an aryl group or a heteroaryl group, each group of which is substituted or unsubstituted, or a pharmaceutically acceptable salt thereof; a medicine comprising the amino compound of Formula (1) or a pharmaceutically acceptable salt; and an angiotensin IV receptor agonist containing the same as an effective component, which are useful, in particular, as a therapeutical drug (antagonist or agonist) for various diseases in which angiotensin IV participates, for example, acceleration of renal blood flow, cerebral vasodilation, inhibition of cell proliferation and hypermnesia.
本发明提供了一种由以下公式表示的氨基化合物:##STR1## 其中X为CH.sub.2 NH或CONH,Y为CH.sub.2 NH或CONH,但X和Y不能同时为CONH;Z为CH.dbd.C(R.sup.4)R.sup.5,CH.sub.2 CH(R.sup.4)R.sup.5或烷氧羰基基团,R.sup.1为氢原子;较低的烷基基团,环烷基基团,环烷基取代烷基基团,芳基基团或取代或未取代的每个基团,R.sup.2和R.sup.3各自独立地为较低的烷基基团或芳基基团,每个基团都是取代或未取代的,R.sup.4和R.sup.5各自独立地为氢原子;烷基基团,芳基基团,杂环芳基基团或取代或未取代的每个基团,或其药学上可接受的盐;包括公式(1)的氨基化合物或其药学上可接受的盐的药物;以及含有其作为有效成分的血管紧张素IV受体激动剂,特别是用于血管紧张素IV参与的各种疾病的治疗药物(拮抗剂或激动剂),例如加速肾血流,脑血管扩张,抑制细胞增殖和超记忆等。
