series of novel 2,4,6-trisubstitutedpyrimidine-5-carboxylic acid derivatives were designed and synthesized with the intent of producing a peroxisome proliferator-activated receptor γ (PPARγ) partial agonist for antidiabetic agents. A pharmacophore-driven approach of in-house screening identified compound 7, which led to the identification of compound 9 featuring a 2,4,6-trisubstituted pyrimidine-5-carboxylic
设计和合成了一系列新颖的2,4,6-三取代嘧啶-5-羧酸衍生物,目的是生产抗糖尿病药的过氧化物酶体增殖物激活受体γ(PPARγ)部分激动剂。药效团驱动的内部筛选方法可鉴定出化合物7,从而鉴定出具有2,4,6-三取代嘧啶-5-羧酸核的化合物9。9的构效关系研究确定了4,6-双苄硫基-2-甲基硫基嘧啶-5-羧酸(50)是所有筛选化合物中最有吸引力的。X射线共晶结构为50PPARγ上的键揭示了与激活功能2(AF-2)位点无关的关键氢键相互作用与完全激动剂的氢键相互作用不同。化合物50在PPARγ-GAL4功能试验中显示出典型的PPARγ部分激动剂特性,并且与罗格列酮相比在3T3-L1细胞中的脂肪细胞分化更弱。此外,尽管有50种药效比罗格列酮弱10倍,但在db / db小鼠中有50种与罗格列酮具有相当的抗糖尿病功效。
