Novel isoquinoline derivatives of the formula ##SPC1## Wherein R.sub.1 is H or, together with R.sub.2, a C--N bond; R.sub.2 is H, R.sub.8 or, together with R.sub.1, a C--N bond; R.sub.3 is H, methyl or ethyl; R.sub.4 and R.sub.5 each are H or collectively a C--C bond; and R.sub.6 and R.sub.7 each are H or methoxy; R.sub.8 being acyl of 1-10 carbon atoms or alkyl of 1-17 carbon atoms optionally mono- or polysubstituted by phenyl, OH, ArCOO--, ArCONH--, piperidino, 3,4-dehydropiperidino, morpholino, carboxy, carbomethoxy and/or carbethoxy, Ar being 3,4,5-trimethoxyphenyl; and the physiologically acceptable acid addition salts and quaternary ammonium salts thereof, have cardiovascular activity and can be prepared by acylating a corresponding primary amine lacking the COAr group with 3,4,5-trimethoxybenzoic acid or a functional derivative thereof.
化合物的化学式为##SPC1## 其中 R.sub.1为氢或与R.sub.2一起形成C-N键; R.sub.2为氢,R.sub.8或与R.sub.1一起形成C-N键; R.sub.3为氢,甲基或乙基; R.sub.4和R.sub.5分别为氢或共同形成C-C键; R.sub.6和R.sub.7分别为氢或甲氧基; R.sub.8为1-10碳原子的酰基或1-17碳原子的烷基,可选择性地被苯基,OH,ArCOO--,ArCONH--,哌啶基,3,4-去氢哌啶基,吗啉基,羧基,羧甲氧基和/或羧乙氧基单独或多个取代,其中Ar为3,4,5-三甲氧基苯基; 以及其生理上可接受的酸加成盐和季铵盐,具有心血管活性,并且可以通过用3,4,5-三甲氧基苯甲酸或其功能衍生物对应的缺乏COAr基团的原始胺进行酰化来制备。
