This invention relates to novel 2-[4-(5-substituted-1,2,4-oxadiazol-3-ylmethoxy)benzyl]-1,2,5-oxadiazolidi ne-3,5-diones which have demonstrated antihyperglycemic activity in diabetic (ob/ob and db/db) mice, genetic animal models of non-insulin dependent diabetes mellitus (NIDDM or Type II diabetes). These compounds are represented by Formula I below: ##STR1## wherein R.sup.1 is C.sub.6 -C.sub.10 aryl, optionally substituted by one to three substituents independently selected from C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, fluorine, chlorine, bromine, iodine, C.sub.1 -C.sub.3 trifluoroalkyl or C.sub.1 -C.sub.3 trifluoroalkoxy; and R.sup.2 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.6 alkyl, fluorine, chlorine, bromine, iodine, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.3 trifluoroalkyl, and C.sub.1 -C.sub.3 trifluoroalkoxy, or a pharmaceutically acceptable salt thereof.
本发明涉及一种新型2-[4-(5-取代-1,2,4-噁二唑-3-基甲氧基)苯甲基]-1,2,5-噁二唑烷-3,5-二酮化合物,该化合物在糖尿病(ob/ob和db/db)小鼠中表现出抗高血糖活性,该小鼠是非胰岛素依赖性糖尿病(NIDDM或2型糖尿病)的遗传动物模型。该化合物由下式I表示:##STR1##其中R1是C6-C10芳基,可选地被一个至三个取自C1-C6烷基,C1-C6烷氧基,氟,氯,溴,碘,C1-C3三氟甲基或C1-C3三氟甲氧基的取代基独立取代;R2选自氢,C1-C6烷基,氟,氯,溴,碘,C1-C6烷氧基,C1-C3三氟甲基和C1-C3三氟甲氧基,或其药学上可接受的盐。
