Benzylidenethiazolidine compounds of formula (I): ##STR1## [in which R.sup.1, R.sup.2 and R.sup.5 are each hydrogen or alkyl; R.sup.3 and R.sup.4 are each hydrogen, alkyl, formyl, alkylcarbonyl, arylcarbonyl, carboxy, alkoxycarbonyl, aryloxycarbonyl, hydroxy, alkylcarbonyloxy, formyloxy, arylcarbonyloxy, optionally substituted alkoxy or halogen; W is methylene, carbonyl or a group of formula >C.dbd.N--OV, wherein V is hydrogen, alkylcarbonyl, arylcarbonyl or optionally substituted alkyl; and n is an integer of from 1 to 3] and salts thereof have the ability to inhibit the formation of lipid peroxide in the mammalian body, and can therefore be used for the treatment of arteriosclerosis and other diseases and disorders arising from an imbalance in the lipid peroxide level. They can also be used for the preparation of the corresponding benzylthiazolidine compounds, which have a generally greater hypoglycemic activity. Processes for the preparation of these compounds of formula (I) are also provided.
Benzylidenethiazolidine化合物的化学式(I):##STR1##[其中R.sup.1,R.sup.2和R.sup.5分别为氢或烷基;R.sup.3和R.sup.4分别为氢、烷基、甲酰基、烷基羰基、芳基羰基、羧基、烷氧羰基、芳氧羰基、羟基、烷基羰氧基、甲酰氧基、芳基羰氧基、可选择取代的烷氧基或卤素;W为亚甲基、羰基或化学式>C.dbd.N--OV的基团,其中V为氢、烷基羰基、芳基羰基或可选择取代的烷基;n为1至3的整数]及其盐具有抑制哺乳动物体内脂质过氧化物形成的能力,因此可用于治疗动脉粥样硬化和其他因脂质过氧化物水平不平衡而引起的疾病和紊乱。它们还可用于制备相应的苯基硫代乙酰胺化合物,其通常具有更强的降糖活性。还提供了制备这些化合物(I)的方法。
