The invention concerns benzoquinolizines of the general formula (I) ##STR1## and the pharmaceutically acceptable acid addition salts thereof, wherein R.sup.1 and R.sup.2 which may be the same or different, each represent hydrogen, lower alkyl, lower alkoxy or halogen and R represents --CXNHR.sup.3 (where X is O, S or .dbd.NH and R.sup.3 is hydrogen or lower alkyl) or --(CH.sub.2).sub.n R.sup.4 (where n is 0 or 1 and R.sup.4 is aryl). These compounds lower blood pressure. Some are also anti-ulcer agents. The compounds in which R.sup.1, R.sup.2 and R are as defined above, with the proviso that when R is phenyl, R.sup.1 and R.sup.2 are not both lower alkoxy, are novel.
本发明涉及通式(I)的苯并喹啉化合物及其药学上可接受的酸盐,其中R.sup.1和R.sup.2可以相同或不同,分别表示氢,低烷基,低烷氧基或卤素,R表示--CXNHR.sup.3(其中X为O,S或.dbd.NH,R.sup.3为氢或低烷基)或--(CH.sub.2).sub.n R.sup.4(其中n为0或1,R.sup.4为芳基)。这些化合物能够降低血压,其中一些还具有抗溃疡作用。当R为苯基时,R.sup.1和R.sup.2不能同时为低烷氧基的化合物是新颖的。
