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.
该文献介绍了一类新型的七元环化合物,化学式为:##STR1## [其中R.sup.1和R.sup.2独立地是氢、卤素、三氟甲基、低碳基或低氧基,或共同形成三或四亚甲基;R.sup.3和R.sup.5独立地是氢、低碳基或芳基碳基;R.sup.4是氢或低碳基;R.sup.6是含有至少一个N、O和S原子作为环形成原子的紧缩或非紧缩杂环,该杂环可能被取代;A是一种烷基链;n为1或2]及其盐。这些化合物表现出抑制肾素-血管紧张素转化酶等活性,并且在循环疾病的诊断、预防和治疗中具有价值,如高血压、心脏病和脑中风。
