Tricyclic imidazole derivatives of the formula ##STR1## wherein R.sup.1 is 2-pyridyl optionally substituted by lower alkyl or lower alkoxy, n is the integer 0 or 1, R.sup.2 is hydrogen or lower alkyl, R.sup.3 and R.sup.4, independently, are hydrogen or lower alkyl, A is a group of the formula ##STR2## m is the integer 2 or 3, R.sup.5, R.sup.6, R.sup.7 and R.sup.8, independently, are hydrogen or lower alkyl, and R.sup.9 is hydrogen and R.sup.10 is hydrogen or lower alkyl or R.sup.9 and R.sup.10 taken together are oxo, provided that at least one of R.sup.3 and R.sup.4 is lower alkyl when A is a group of the formula --CH.dbd.CH--CH.dbd.CH-- or --(CH.sub.2).sub.4 --, and their pharmaceutically acceptable acid addition salts. The compounds of formula I inhibit gastric acid secretion and prevent the formation of gastric ulcers.
公式为 ##STR1## 的三环咪唑衍生物,其中R.sup.1是2-吡啶基,可选择地被低烷基或低烷氧基取代,n是整数0或1,R.sup.2是氢或低烷基,R.sup.3和R.sup.4独立地是氢或低烷基,A是公式 ##STR2## 的基团,m是整数2或3,R.sup.5,R.sup.6,R.sup.7和R.sup.8独立地是氢或低烷基,R.sup.9是氢,R.sup.10是氢或低烷基或R.sup.9和R.sup.10一起是氧代,但当A是公式--CH.dbd.CH--CH.dbd.CH--或--(CH.sub.2).sub.4--的基团时,至少R.sup.3和R.sup.4中的一个是低烷基,它们的药学上可接受的酸盐。公式I的化合物抑制胃酸分泌并预防胃溃疡的形成。
