This invention encompasses orally effective antiulcer agents of the formula ##STR1## wherein X is hydroxy, (C.sub.1 -C.sub.5)-alkoxy, phenoxy, benzyloxy, or --NH(CH.sub.2).sub.n Y wherein n is an integer of value 2 to 4 and Y is di-(C.sub.1 -C.sub.3)-alkylamino, 1-pyrrolidinyl, 1-piperidinyl or 4-morpholinyl; R' and R" when taken together are (C.sub.3 -C.sub.8)-alkylene, with the proviso that the ring so formed is 5- to 8-membered; R' and R" when taken separately are each independently hydrogen, (C.sub.1 -C.sub.6)-alkyl or (C.sub.5 -C.sub.6)-cycloalkyl, with the proviso that when X is other than --NH(CH.sub.2).sub.n Y, at least one of R' and R" is other than hydrogen; the pharmaceutically acceptable cationic salts thereof when X is hydroxyl, and the pharmaceutically acceptable anionic salts thereof when X is --NH(CH.sub.2).sub.n Y.
这项发明涵盖了以下结构的口服抗溃疡药物:##STR1## 其中 X 是羟基、(C.sub.1 -C.sub.5)-烷氧基、苯氧基、苄氧基,或--NH(CH.sub.2).sub.n Y,其中 n 是值为 2 到 4 的整数,Y 是双-(C.sub.1 -C.sub.3)-烷基氨基、1-吡咯啉基、1-哌啶基或 4-吗啉基;当 R' 和 R" 结合在一起时为 (C.sub.3 -C.sub.8)-烷基烯,但所形成的环为 5 至 8 个成员;当 R' 和 R" 分别取时,它们各自独立地是氢、(C.sub.1 -C.sub.6)-烷基或 (C.sub.5 -C.sub.6)-环烷基,但当 X 不是 --NH(CH.sub.2).sub.n Y 时,R' 和 R" 中至少有一个不是氢。当 X 是羟基时,其在药学上可接受的阳离子盐,当 X 是 --NH(CH.sub.2).sub.n Y 时,其在药学上可接受的阴离子盐。
