PTP1B serving as a key negative regulator of insulin signaling is a novel target for type 2 diabetes and obesity. Modification at ring B of N-4-[(3-Phenyl-ureido)-methyl]-phenyl}-methane-sulfonamide template to interact with residues Arg47 and Lys41 in the C site of PTP1B by molecular docking aided design resulted in the discovery of a series of novel high potent and selective inhibitors of PTP1B
PTP1B作为胰岛素信号的关键负调节剂,是2型糖尿病和肥胖症的新靶标。通过分子对接辅助设计修饰N- 4-[(3-苯基-脲基)-甲基]-苯基}-甲烷磺酰胺模板的B环,使其与PTP1B C位的残基Arg47和Lys41相互作用。发现一系列新型的PTP1B高效抑制剂。与PTP1B的C位点相互作用的结构活性关系已得到很好的说明。化合物8和18被证明是高效,最有前途的PTP1B抑制剂,与高度同源的TCPTP和其他PTP相比,具有细胞活性和极大的选择性。
