  Discovery of 6-(2,4-Difluorophenoxy)-2-[3-hydroxy-1-(2-hydroxyethyl)propylamino]-8-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (Pamapimod) and 6-(2,4-Difluorophenoxy)-8-methyl-2-(tetrahydro-2H-pyran-4-ylamino)pyrido[2,3-d]pyrimidin-7(8H)-one (R1487) as Orally Bioavailable and Highly Selective Inhibitors of p38α Mitogen-Activated Protein Kinase

  摘要：

  The development of a new series of p38 alpha inhibitors resulted in the identification of two clinical candidates, one of which was advanced into a phase 2 clinical study for rheumatoid arthritis. The original lead, an lck inhibitor that also potently inhibited p38a, was a screening hit from our kinase inhibitor library. This manuscript describes the optimization of the lead to p38-selective examples with good pharmacokinetic properties.

  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。
