Abstract

Activation of various interacting stress Kinases, particularly the c-Jun N-terminal Kinases (JNK), and a concomitant phosphorylation of Insulin Receptor 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 and Type 2 Diabetes.
