A compound represented by the formula (I)
wherein one of R1 and R2 is a hydrogen atom or a substituent and the other is an optionally substituted cyclic group;
W is a bond or a divalent aliphatic hydrocarbon group;
Y is a group of the formula: -OR3 (wherein R3 is a hydrogen atom, an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted acyl group) or an optionally esterified or amidated carboxyl group, or a salt thereof or a prodrug thereof has a superior insulin secretion promoting action and a hypoglycemic action and shows low toxicity. Therefore, the compound is useful as a pharmaceutical agent, particularly as an agent for the prophylaxis or treatment of diabetes and diabetic complications, and the like.
由式(I)代表的化合物
其中 R1 和 R2 中的一个是氢原子或取代基,另一个是任选取代的环状基团;
W 是键或二价脂族烃基;
Y 是式中的一个基团:-OR3(其中 R3 是氢原子、任选取代的烃基、任选取代的杂环基或任选取代的酰基)或任选酯化或酰胺化的羧基,或其盐或其原药具有优异的促进胰岛素分泌作用和降血糖作用,且毒性低。因此,该化合物可用作药物制剂,特别是用于预防或治疗糖尿病和糖尿病并发症等。
