A thiazolidine derivative represented by general formula (1), a salt thereof, a process for producing the same, a pharmaceutical composition containing the same as the active ingredient, and a method of treating diabetes by administering the same, wherein R<1>, R<2> and R<3> represent each independently hydrogen, halogen, optionally halogenated lower alkyl or lower alkoxy, hydroxy, nitro, amino, lower acylamino, mono- or di(lower alkyl)amino, carboxy, lower alkoxycarbonyl, cyano, 2-oxazolyl, thiazolidine-2,4-dione-5-ylidenemethyl or thiazolidine-2,4-dione-5-ylmethyl, provided R<1> and R<2> may be combined together to form an alkylene chain -(CH2)p- (where p represents 3, 4 or 5) or an alkylenedioxy chain -O(CH2)qO- (where q represents 1, 2 or 3) to thereby represent a ring; R<4> and R<5> represent each independently hydrogen or lower alkyl; X represents carbon or nitrogen; Y represents oxygen or imino; A and B represent each lower alkylene; m represents a number of 0 or 1; and the broken line indicates that there may be a double bond. This compound is excellent in the effect of lowering blood sugar and lipid levels, can well be absorbed in the living organism and retain its effect therein for long, can well be excreted, and is lowly toxic for the human body. <CHEM> |
