A geranylgeranylacetamide compound having a piperazine ring represented by the following formula (I) ##STR1## wherein R represents a member selected from the class consisting of a hydrogen atom, C.sub.1 -C.sub.5 alkyl groups which are unsubstituted or mono-substituted by a halogen atom, C.sub.2 -C.sub.5 alkenyl groups and C.sub.7 -C.sub.8 aralkyl groups, R.sub.1 represents a C.sub.1 -C.sub.3 alkyl group, and n represents 0, 1 or 2, and a pharmaceutically acceptable acid addition salt thereof. The aforesaid compound can be prepared by reacting geranylgeranylacetic acid or its reactive derivative with a piperazine compound, and thereafter, if desired, transforming the free geranylgeranylacetamide compound thus obtained into its pharmaceutically acceptable acid addition salt. A pharmaceutical composition containing said compound exhibits antiulcerogenic activity, particularly excellent antipeptic ulcerogenic activity, and is useful as an agent for treating ulcers.
一种具有哌嗪环的生脂醇酰乙酰胺化合物,其化学式表示为(I)##STR1##其中,R代表选自氢原子,C.sub.1-C.sub.5烷基,其未经卤原子单取代或未取代,C.sub.2-C.sub.5烯基和C.sub.7-C.sub.8芳基烷基的成员,R.sub.1代表C.sub.1-C.sub.3烷基,n代表0、1或2,以及其药学上可接受的酸盐。上述化合物可通过将生脂酰乙酸或其反应性衍生物与哌嗪化合物反应制备而成,然后,如有需要,将所得的游离生脂醇酰乙酰胺化合物转化为其药学上可接受的酸盐。含有该化合物的制药组合物表现出抗溃疡活性,特别是出色的抗胃溃疡活性,并且可用作溃疡治疗剂。
