This invention relates to compounds having the general formula: ##STR1## WHEREIN W represents a phenyl or indolyl radical, either of which radicals may be unsubstituted or substituted by halogen, lower alkyl, lower alkoxy or hydroxy. A represents a lower alkylene radical, an oxo lower alkylene radical or a hydroxy lower alkylene radical; R represents a phenyl radical optionally substituted by halogen, lower alkyl, lower alkoxy or hydroxy, a cycloalkyl radical of 5 to 7 carbon atoms or a lower alkyl radical; R.sup.1 represents hydrogen or a lower alkyl radical or a pharmaceutically acceptable acid addition or quaternary ammonium salt thereof; which possess hypotensive activity.
本发明涉及具有以下一般式的化合物:##STR1## 其中W代表苯基或
吲哚基,这两种基团可以是未取代的或被卤素、低烷基、低烷氧基或羟基取代的;A代表低烷基烷基、氧代低烷基烷基或羟基低烷基烷基;R代表苯基,可选地被卤素、低烷基、低烷氧基或羟基取代,5到7个碳原子的环烷基或低烷基;R.sup.1代表氢或低烷基基团或其药学上可接受的酸盐或季
铵盐;这些化合物具有降压活性。
