The invention relates to quinoline derivatives of the formula (I) ##STR1## and the pharmaceutically acceptable acid addition salts of those compounds capable of forming acid addition salts. In formula (I), R.sup.1 and R.sup.2 which may be the same of different each represent hydrogen, lower alkyl, lower alkoxy, trifluoromethyl or halogen, R.sup.3 and R.sup.4 which may be the same or different each represent lower alkyl and X represents hydroxy, halogen, hydrazino, or a radical of formula -NR.sup.5 R.sup.6 where R.sup.5 and R.sup.6 which may be the same or different each represent hydrogen or lower alkyl or R.sup.5 and R.sup.6 together with the nitrogen atom to which they are both attached represent a saturated heterocyclic ring containing 5 to 7 ring atoms. The compounds possess hypotensive activity.
本发明涉及公式(I)的喹啉衍生物##STR1##和那些能够形成酸加合盐的化合物的药学上可接受的酸加合盐。在公式(I)中,R.sup.1和R.sup.2可以相同也可以不同,分别代表氢、低级烷基、低级烷氧基、三氟甲基或卤素,R.sup.3和R.sup.4可以相同也可以不同,分别代表低级烷基,X代表羟基、卤素、肼基或者公式-NR.sup.5 R.sup.6的基团,其中R.sup.5和R.sup.6可以相同也可以不同,分别代表氢或低级烷基,或者R.sup.5和R.sup.6与它们所连接的氮原子共同代表含有5到7个环原子的饱和杂环环。这些化合物具有降压活性。
