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 >N--R.sup.7 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.
本发明提供了苯二氮平类衍生物,其一般式为##STR1##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代表氢或卤素原子,R.sup.5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R.sup.5代表芳基或较低的芳基烷基,或R.sup.5和R.sup.6与它们连接的氮原子一起代表一个3-7环杂环,当它至少为5环时,可以包含一个氧或硫原子或一个公式>N-R.sup.7的基团,其中R.sup.7代表氢原子或较低的烷基,并且其药物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吸收,因此适用于预防或控制动脉粥样硬化。还提供了用于制造上述终产品和新型中间体的方法。
