Novel 3-amino-4-oxo-2,3,4,5-tetrahydro-1,5-benzoxazepine derivatives 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 is hydrogen, optionally substituted lower alkyl or optionally substituted aralkyl; R.sup.4 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 2] and salts thereof. These compounds and salts thereof exhibits 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 apoploxy).
新颖的3-氨基-4-酮基-2,3,4,5-四氢-1,5-苯并噁唑啉衍生物的化学式为##STR1##[其中R.sup.1和R.sup.2独立地为氢、卤素、三氟甲基、低碳烷基或低碳氧基,或者共同形成三元或四元亚甲基;R.sup.3为氢、可选择取代的低碳烷基或可选择取代的芳基烷基;R.sup.4为氢、可选择取代的烷基、可选择取代的芳基烷基或可选择取代的环烷基烷基;Y为可酯化或酰胺化的羧基;m为1或2]及其盐。这些化合物及其盐对肾素转换酶等具有抑制活性,可作为循环系统疾病(如高血压、心脏病、脑卒中)的诊断、预防和治疗药物。
