thiazolopyrimidine derivatives was designed, synthesized and screened for in‐vitro inhibition of Dipeptidyl Peptidase IV (DPP IV). The SAR study indicated the influence of substituted chemical modifications on thiazolopyrimidine scaffold. Compound 9 (IC50 = 0.489 μm) and 10 (IC50 = 0.329 μm) having heterocyclic‐substituted piperazine with acetamide linker resulted as most potent DPP IV inhibitors among all the compounds
设计,合成和筛选了一系列噻唑并嘧啶衍生物,用于体外抑制二肽基肽酶IV(DPP IV)。SAR研究表明取代的化学修饰对噻唑并嘧啶骨架的影响。化合物9(IC 50 = 0.489μ米)和10(IC 50 = 0.329μ米具有乙酰胺接头杂环取代的哌嗪),导致在所有的化合物筛选作为最有力的DPP IV抑制剂。化合物9和10的单剂量(10 mg / kg)在链脲佐菌素诱发的糖尿病大鼠模型中,口服葡萄糖耐量试验期间,葡萄糖的摄取显着降低。分子对接研究表明了噻唑并嘧啶核及其衍生物在受体结合位点的可能结合方式和相互作用。DPP IV的结合位点由活性位点区域(Ser630,Asp708和His740的催化三联体)组成,包括S1和S2亚口袋。化合物的芳基部分9,10和11观察到它们占据S2结合口袋并与通过π-π相互作用获得的Tyr662和Tyr666的芳香环相互作用。因此,表明对DPP IV抑制活性而言,高度疏水的S
