The present invention provides new tricyclic benzotriazoles of the general formula: ##STR1## wherein Z is a hydrogen atom or an acyl radical, Y is an oxygen or sulphur atom or two hydrogen atoms and X is an oxygen or sulphur atom or a >CR.sub.1 R.sub.2 or >NR.sub.3 group, R.sub.1 is a hydrogen atom or an alkyl, alkenyl or cycloalkyl radical, R.sub.2 is a hydrogen atom or an alkyl, alkenyl or cyano group or a carbonyl group substituted by a hydroxyl, alkyl, alkoxy, amino, alkylamino, dialkylamino or hydrazino group or R.sub.2, together with R.sub.1, represents a cycloalkylene radical or R.sub.1 and R.sub.2 together form an alkylidene or cycloalkylidene radical and R.sub.3 is a hydrogen atom or an alkyl radical; the tautomers thereof and the physiologically acceptable acid-addition salts thereof with inorganic and organic acids. The present invention also provides processes for the preparation of these tricyclic benzotriazoles and pharmaceutical compositions containing them for the treatment of heart and circulatory diseases.
本发明提供了一种新的三环苯并三唑的一般式:##STR1## 其中Z是氢原子或酰基基团,Y是氧或硫原子或两个氢原子,X是氧或硫原子或一个>CR.sub.1 R.sub.2或>NR.sub.3基团,R.sub.1是氢原子或烷基,烯基或环烷基基团,R.sub.2是氢原子或烷基,烯基或氰基或羰基,被羟基,烷基氧基,氨基,烷基氨基,二烷基氨基或肼基取代的羰基基团或者R.sub.2与R.sub.1一起表示环烷基基团或R.sub.1和R.sub.2一起形成烷基亚甲基或环烷基亚甲基基团,R.sub.3是氢原子或烷基基团;它们的互变异构体和与无机和有机酸的生理可接受的酸加成盐。本发明还提供了制备这些三环苯并三唑的方法和含有它们的制药组合物,用于治疗心脏和循环系统疾病。
