Various analogues of a new antidiabetic agent, pioglitazone (AD-4833, U-72107), were synthesized in order to study in more detail the structure-activity relationships of this class of drug. 5-(4-Pyridylalkylthiobenzyl)-2,4-thiazolidinediones (I), thia-analogues of pioglitazone, were prepared via Meerwein arylation of the alkylthioanilines (IV). 5-(4-Pyridylalkoxybenzylidene)-2,4-thiazolidinediones
为了更详细地研究这类药物的构效关系,合成了一种新的抗糖尿病药吡格列酮(AD-4833,U-72107)的各种类似物。通过烷基硫代苯胺(IV)的Meerwein芳基化制备5-(4-吡啶基烷基硫代苄基)-2,4-噻唑烷二酮(I),吡格列酮的硫代类似物。通过醛(VIII)与相应的偶氮立酮的Knoevenagel缩合反应,合成了5-(4-吡啶基烷氧基亚苄基)-2,4-噻唑烷二酮(IIa)和相关的杂环类似物(IIb)。评价了化合物I和II在遗传性肥胖和糖尿病黄色KK(KKAy)小鼠中的降血糖和降血脂活性。几个5- [4- [2-(2-吡啶基)乙氧基]-亚苄基] -2,4-噻唑烷二酮(IIa)与吡格列酮等效。然而,硫代类似物(I)和亚苄基杂环(IIb)的活性降低。发现5-亚苄基类似物(14)的催化氢化是吡格列酮的方便的新合成方法。还讨论了14的配置。
