This invention provides benzodiazepine derivatives of the general formula ##STR1## wherein R.sup.1 represents a lower alkyl group, R.sup.2 represents a hydrogen atom or a lower alkyl group, R.sup.3 represents a halogen atom and R.sup.4 represents a hydrogen or halogen atom and either R.sup.5 represents a hydrogen atom or a lower alkyl group and R.sup.6 represents a lower alkyl, lower hydroxyalkyl or lower acyloxyalkyl group or R.sup.5 represents a hydrogen atom and R.sup.6 represents an aryl or lower aralkyl group or R.sup.5 and R.sup.6 together with the nitrogen atom to which they are attached represent a 3-membered to 7-membered heterocycle which, when it is at least 5-membered, can contain as a ring member an oxygen or sulphur atom or a group of the formula ##STR2## in which R.sup.7 represents a hydrogen atom or a lower alkyl group, and pharmaceutically acceptable acid addition salts thereof, which possess aldosterone-antagonistic properties and are accordingly suitable for the control or prevention of heart failure, of hepatic ascites, of primary aldosteronism and of idiopathic hypertension. Some of these compounds and salts also inhibit the intestinal resorption of cholesterol and are according suitable for the prevention or control of atherosclerosis. Also provided are a process for the manufacture of the above end products and novel intermediates therefor.
本发明提供了一般式为 ##STR1## 的苯二氮平衍
生物,其中 R.sup.1 代表较低的烷基,R.sup.2 代表氢原子或较低的烷基,R.sup.3 代表卤素原子,R.sup.4 代表氢原子或卤素原子,R.sup.5 要么代表氢原子或较低的烷基,R.sup.6 代表较低的烷基、较低的羟基烷基或较低的酰氧基烷基,或者 R.sup.5 代表氢原子且 R.sup.6 代表芳基或较低的芳基烷基,或者 R.sup.5 和 R.sup.6 与它们所连接的氮原子一起代表一个3-7元杂环,当它至少为5元时,可以包含作为环成员的氧原子或
硫原子或具有公式 ##STR2## 的基团,其中 R.sup.7 代表氢原子或较低的烷基,并且其药学上可接受的酸盐具有
醛固酮拮抗作用,因此适用于控制或预防心力衰竭、肝性腹
水、原发性
醛固酮增多症和特发性高血压。其中一些化合物和盐还抑制
胆固醇的肠道吸收,因此适用于预防或控制动脉粥样硬化。此外,还提供了制造上述终产品和新型中间体的方法。
