-yl)[2-(2-pyridylamino)ethyl]amine analogues which are inhibitors of human glycogen synthase kinase 3 (GSK3). We developed efficient synthetic routes to explore a wide variety of substitution patterns and convergently access a diverse array of analogues. Compound 1 (CHIR-911, CT-99021, or CHIR-73911) emerged from an exploration of heterocycles at the C-5 position, phenyl groups at C-4, and a variety
为了鉴定新的抗糖尿病药,我们发现了一种新型的(5-咪唑-2--2-基-4-苯基嘧啶-2-基)[2-(2-吡啶基氨基)乙基]胺类似物,它们是人类的抑制剂。糖原合酶激酶3(GSK3)。我们开发了有效的合成路线来探索各种取代模式,并会聚各种类似物。化合物1(CHIR-911,CT-99021或CHIR-73911)来自对C-5位置的杂环,C-4的苯基以及C处连接的各种不同取代的连接基和氨基吡啶部分的探索-2位置。这些化合物表现出GSK3 IC 50在低纳摩尔范围内和出色的选择性。它们激活表达胰岛素受体的CHO-IR细胞和原代大鼠肝细胞中的糖原合酶。在2型糖尿病的啮齿动物模型中对先导化合物1和2(CHIR-611或CT-98014)的评估表明,单次口服剂量可在60分钟内降低高血糖症,增强胰岛素刺激的葡萄糖转运,并改善葡萄糖的处置而不增加胰岛素水平。
