Novel farnesylacetic acid ester derivatives containing an amine nitrogen in the alcohol residue thereof and represented by the following general formula exhibit high levels of antiulcerogenic activity and very low levels of toxicity: ##STR1## wherein A is an alkylene radical containing at least 2 carbon atoms; R.sup.1 is H, alkyl, cycloalkyl, aryl, aralkyl or alkenyl; R.sup.2 and R.sup.3 are independently H, alkyl, aryl, aralkyl or alkenyl or one of R.sup.2 and R.sup.3 forms, together with A, a piperidine, pyrrolidine, tetrahydropyrimidine or piperazine ring which contains the nitrogen atom lying therebetween or R.sup.2 and R.sup.3 combine to form, together with the adjacent nitrogen atom, a piperazine ring; provided that the total number of carbon atoms contained in A, R.sup.1, R.sup.2 and R.sup.3 is at least 5.
含有醇残基中胺基氮的新型法尼酰乙酸酯衍生物,由下列通式表示,表现出高水平的抗溃疡活性和极低的毒性: ##STR1## 其中A是至少含有2个碳原子的烷基基团;R.sup.1是H、烷基、环烷基、芳基、芳基烷基或烯基;R.sup.2和R.sup.3独立地是H、烷基、芳基、芳基烷基或烯基,或者R.sup.2和R.sup.3与A一起形成哌啶、吡咯烷、四氢嘧啶或哌嗪环,其中含有氮原子,或者R.sup.2和R.sup.3与相邻的氮原子结合形成哌嗪环;前提是A、R.sup.1、R.sup.2和R.sup.3中所含的碳原子总数至少为5。
