(a) Tetrahydroquinoline derivatives and salts thereof represented by the formula,
(wherein R1aand R2a are the same or different from each other, and are each hydrogen, halogen, hydroxy, alkyl, afkoxy. alkenyloxy, alkynyloxy or alkoxy-alkoxy; R3a and R4a are the same or different from each other, and are each hydrogen, a halogen, alkyl having to 3 halogen atoms as the substituents alkoxy, alkyl, nitro or alkanoyl; ( is 0 or 1; and
(b) imidazopyndme derivatives and salts thereof represented by the formula,
(wherein any one of Z and Y is -CH=, then the other one is a nitrogen; R1b and R2b are the same or different from each other, and are each hydrogen, alkoxycarbonyl, halogen, alkyl, amino or hydroxy; R3b, R4b and f5b are the same or different from each other, and are each hydrogen, alkoxy or alkyl; A is alkylene group; ( is 0 or 1; provided that when Y is -CH=, Z is a nitrogen atom, and ( is 0, then R3b, R4b and R5b should not be hydrogen at the same time) both having excellent anti-peptic ulcer activities, and are useful as treating agents for peptic ulcers such as gastric ulcer, duodenum ulcer and the like.
(a) 式中的四氢喹啉衍生物及其盐、
(其中 R1a 和 R2a 彼此相同或不同,并且各自为氢、卤素、羟基、烷基、烷氧基、烯氧基、炔氧基或 烷氧基-烷氧基;R3a 和 R4a 彼此相同或不同,并且各自为氢、卤素、具有至 3 个卤素原子作为取代基的烷氧基、烷基、硝基或烷酰基;( 为 0 或 1;以及
(b) 由以下式子表示的咪唑炔二甲胺衍生物及其盐类、
(其中 Z 和 Y 的任何一个是-CH=,则另一个是氮;R1b 和 R2b 彼此相同或不同,并且各自是氢、烷氧基羰基、卤素、烷基、氨基或羟基;R3b、R4b 和 f5b 彼此相同或不同,并且各自是氢、烷氧基或烷基;A为亚烷基;( 为 0 或 1;但当 Y 为 -CH=,Z 为氮原子,且( 为 0 时,则 R3b、R4b 和 R5b 不应同时为氢),两者均具有优异的抗消化性溃疡活性,可用作胃溃疡、十二指肠溃疡等消化性溃疡的治疗剂。
