蛋白酪氨酸磷酸酶1B (PTP1B)作为胰岛素和瘦素信号转导通路的负调节因子, 已成为治疗糖尿病和肥胖症的潜在靶标. 为了寻找非磷酸酯类PTP1B抑制剂, 设计、合成了一系列(E)-1-取代苯基-3-[4-((E)-(2-(4-苯基噻唑-2-基)腙)甲基)苯基]-2-丙烯-1-酮(4a4n), 并对化合物进行了PTP1B抑制活性测定. 结果显示, 所有化合物对PTP1B均显示出较强的抑制活性, 其中化合物4h活性最佳, IC50为(2.57±0.50) μmol·L-1.

Protein tyrosine phosphatase 1B (PTP1B) has recently been identified as new drug target for type II diabetes and obesity due to that it is a negative regulator of the insulin and leptin-signaling pathway. In order to find new nonphosphonate-based pTyr mimetics, a series of novel (E)-1-phenyl-3-(4-((E)-(2-(4-phenyl-thiazol-2-yl)hydrazono)methyl)phenyl)-prop-2-en-1-one (4a4n) were designed, synthesized, and evaluated for their PTP1B inhibitory activity. The results demonstrated that all compounds presented potent inhibitory activities against PTP1B, among which compound 4h exhibited most potent with IC50 value of (2.57±0.50) μmol·L-1.
