Protein tyrosine phosphatase 1B (PTP1B) is a key negative regulator of insulin signaling pathway. Inhibition of PTP1B is expected to improve insulin action. Appropriate selectivity and permeability are the gold standard for excellent PTP1B inhibitors. In this work, molecular hybridization-based screening identified a selective competitive PTP1B inhibitor. Compound 10a has IC50 values of 199 nM against
蛋白酪氨酸磷酸酶1B(PTP1B)是胰岛素信号通路的关键负调控因子。抑制PTP1B有望改善胰岛素作用。适当的选择性和渗透性是优秀PTP1B抑制剂的金标准。在这项工作中,基于分子杂交的筛选确定了选择性竞争性PTP1B抑制剂。化合物10a对PTP1B的IC50值为199 nM,并且与紧密相关的磷酸酶TCPTP相比,对PTP1B的选择性高32倍。分子对接和分子动力学研究揭示了PTP1B相对于TCPTP选择性的原因。另外,分别说明化合物10a的细胞透过性和细胞活性。
