4-Ainoquinoline derivatives having the general formula
and their pharmaceutically acceptable acid addition salts, wherein X is trifluoromethyl or halogen, Z is hydrogen, halogen, lower alkyl, lower alkoxy, nitro, di(lower alkyl) amino or trifluoromethyland R is a proup having one of the formulae
and
wherein R' is hydrogen or lower alkyl, R2 is lower alkyl, R3 is lower alkyl and A is lower alkylene, are disclosed. The 4-aminoquinoline derivatives may be prepared by acylation of an amine RH or an activated derivative thereof with an acid (formula IV, R=OH) or a reactive derivative thereof or by reacting aniline substituted on the ring by Z and -COR to introduce the 8-(trifluoromethyl or halo) 4-quinolyl radical. The 4-aminoquinoline derivatives show analgesic activity and, in some cases, anti-inflammatory activity and may therefore be included in pharmaceutical compositions containing a pharmaceutically acceptable carrier.
具有通式的 4-氨基喹啉衍生物
及其药学上可接受的酸加成盐,其中 X 是三氟甲基或卤素,Z 是氢、卤素、低级烷基、低级烷氧基、硝基、二(低级烷基)氨基或三氟甲基,R 是具有以下式子之一的基团
和
其中 R' 为氢或低级烷基,R2 为低级烷基,R3 为低级烷基,A 为低级亚烷基。4- 氨基喹啉衍生物可通过胺 RH 或其活化衍生物与酸(式 IV,R=OH)或其活性衍生物酰化,或通过使环上被 Z 和 -COR 取代的苯胺反应引入 8-(三氟甲基或卤代)4-喹啉基来制备。4- 氨基喹啉衍生物具有镇痛活性,在某些情况下还具有抗炎活性,因此可用于含有药学上可接受的载体的药物组合物中。
