substrate 1 (IRS-1) at serine 307 play a central role both in insulin resistance and in β-cell dysfunction. IRS-1 phosphorylation is stimulated by elevated free fatty acid levels through different pathways in obesity. A series of novel pyrido[2,3-d]pyrimidin-7-one derivatives were synthesized as potential antidiabetic agents, preventing IRS-1 phosphorylation at serine 307 in a cellular model of lipotoxicity
各种相互作用的应激激酶,特别是c-Jun N末端激酶(JNK)的激活,以及伴随着丝氨酸307的胰岛素受体底物1(IRS-1)的磷酸化,在胰岛素抵抗和β细胞中均起着中心作用功能障碍。通过肥胖中不同途径的升高的游离脂肪酸水平可刺激IRS-1磷酸化。合成了一系列新型的吡啶并[2,3 - d ]嘧啶-7-衍生物,作为潜在的抗糖尿病药,可防止脂毒性和2型糖尿病细胞模型中IRS-1在丝氨酸307的磷酸化。
