Novel condensed seven-membered ring compounds of the formula: ##STR1## [wherein R.sup.1 and R.sup.2 are independently hydrogen, halogen, trifluoromethyl, lower alkyl or lower alkoxy, or both jointly form tri- or tetramethylene; R.sup.3 and R.sup.5 are independently hydrogen, lower alkyl or aralkyl; R.sup.4 is hydrogen or lower alkyl; R.sup.6 is a condensed or non-condensed hetero-alicyclic containing at least one atom of N, O and S as a ring-forming atom which may be substituted; A is an alkylene chain; n is 1 or 2] and salts thereof. These compounds 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, such as hypertension, cardiopathy and cerebral apoploxy.
这是一种化合物的化学式:##STR1## [其中R.sup.1和R.sup.2分别为氢、卤素、三氟甲基、低碳基或低碳氧基,或共同形成三亚甲基或四亚甲基;R.sup.3和R.sup.5分别为氢、低碳基或芳基低碳基;R.sup.4为氢或低碳基;R.sup.6为含有至少一个N、O和S原子作为环形成原子的紧缩或非紧缩杂环,可以被取代;A是一个烷基链;n为1或2]和它们的盐。这些化合物表现出对血管紧张素转换酶等的抑制活性,并且作为诊断、预防和治疗循环系统疾病(如高血压、心脏病和脑中风)的药物具有价值。
