Novel condensed, seven-membered ring compounds of the formula
[wherein R' and R2 are independently hydrogen, halogen, trifluoromethyl, lower alkyl or lower alkoxy, or both jointly form tri- or tetramethylene; R3 is hydrogen, optionally substituted lower alkyl or optionally substituted aralkyl; R4 is hydrogen, optionally substituted alkyl, optionally substituted aralkyl or optionally substituted cycloalkylalkyl; Y is a carboxyl group which may be esterified or amidated; m is 1 or 21 and salts thereof.
These compounds and salts thereof exhibit inhibitory activity on angiotensin converting enzyme and so forth, and are of value as an agent for diagnosis, prevention and treatment of circulatory diseases (e.g. hypertension, cardiopathy, cerebral apoplexy).
式中的新型缩合七元环化合物
[其中 R' 和 R2 独立地为氢、卤素、三氟甲基、低级烷基或低级烷氧基,或二者共同形成三亚甲基或四亚甲基;R3 为氢、任选取代的低级烷基或任选取代的芳烷基;R4 为氢、任选取代的烷基、任选取代的芳烷基或任选取代的环烷基;Y 为可酯化或酰胺化的羧基;m 为 1 或 21 及其盐。
这些化合物及其盐类对血管紧张素转换酶等具有抑制活性,具有诊断、预防和治疗循环系统疾病(如高血压、心脏病、脑中风)的价值。
