This invention relates to benzothiazepine derivatives of the general formula ##STR1## where K is hydrogen or a --CH.sub.2 COOR.sub.2 group where R.sub.2 is hydrogen or a lower alkyl group, Z is hydrogen or phenyl except when both K and Z are hydrogen, and Y is hydrogen, a --CHR.sub.3 --COOR.sub.1 group, an alkanoyl group or a --COO(CH.sub.2).sub.n R.sub.4 group where R.sub.1 is hydrogen or a lower alkyl group, R.sub.3 is hydrogen, an alkyl group, an alkylphenyl group or an aryl-lower alkyl group, R.sub.4 is an aryl group and n is a whole number of 1 to 10, and to their methods of preparation. The benzothiazepine derivatives of this invention, including their salts, have a powerful inhibitory effect on the angiotensin converting enzyme and exert a marked depressor effect in such models of hypertension as spontaneously occurring hypertensive rats and the like, so that they are useful as drugs for the treatment of hypertension and other cardiovascular diseases. In addition, these compounds are also useful as intermediates for the synthesis of coronary dilators, psychotropic drugs and the like.
本发明涉及一般式 ##STR1## 的苯并噻二唑衍生物,其中 K 是氢或 --CH.sub.2 COOR.sub.2 域,其中 R.sub.2 是氢或较低烷基,Z 是氢或苯,除非 K 和 Z 同时为氢,Y 是氢,一个 --CHR.sub.3 --COOR.sub.1 域,一个烷酰基或一个 --COO(CH.sub.2).sub.n R.sub.4 域,其中 R.sub.1 是氢或较低烷基,R.sub.3 是氢,烷基,烷基苯基或芳基-较低烷基,R.sub.4 是芳基,n 是 1 到 10 的整数,以及它们的制备方法。本发明的苯并噻二唑衍生物,包括它们的盐,在抑制肾素-血管紧张素转化酶方面具有强大的作用,并在自发性高血压大鼠等高血压模型中表现出明显的降压作用,因此它们可用作治疗高血压和其他心血管疾病的药物。此外,这些化合物还可用作合成冠状扩张剂、精神药物等的中间体。
