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通式的化合物:##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取代为卤素,较低的烷基,较低的烷氧基或羟基。A代表较低的烷基烯基基团,氧代较低的烷基烯基基团或羟基较低的烷基烯基基团;R代表苯基基团,该基团可以选择性地被卤素,较低的烷基,较低的烷氧基或羟基取代,环烷基基团,其碳原子数为5到7,或较低的烷基基团;R.sup.1代表氢或较低的烷基基团,或其药学上可接受的酸加合物或季铵盐;这些化合物具有降压活性。
