The specification describes as antiulcer drug containing as an active ingredient a 2,3-butanediol diester derivative represented by the formula (I):
where RA may for example be a saturated or unsaturated alkyl or phenyl styryl group and RB may for example be a saturated or unsaturated alkyl, phenyl, phenylalkyl, phenylpropenyl or phenoxyalkyl group. These groups may optionally be substituted. Many of 2,3-butanediol diester derivatives embraced by the formula (I) are novel. Also described are a novel process for preparing such novel 2,3-butanediol diester derivatives. The 2,3-butandiol diester derivatives of the formula (I) has an action to depress strongly the growth of peptic ulcer and has a very low toxicity.
本说明书描述了一种抗溃疡药物,其活性成分是由式(I)表示的 2,3-丁二醇二酯衍生物:
其中 RA 可以是饱和或不饱和烷基或苯基苯乙烯基,RB 可以是饱和或不饱和烷基、苯基、苯基烷基、苯基丙烯基或苯氧基烷基。这些基团可以选择性地被取代。式 (I) 所包含的许多 2,3-丁二醇二酯衍生物都是新颖的。此外,还介绍了制备此类新型 2,3-丁二醇二酯衍生物的新工艺。式(I)中的 2,3-丁二醇二酯衍生物具有强烈抑制消化性溃疡生长的作用,且毒性极低。
