Two series of 1,3-diphenyl-1H-pyrazole derivatives containing rhodanine-3-alkanoic acid groups were identified as competitive protein tyrosine phosphatase 1B (PTP1B) inhibitors. Among the compounds studied, IIIv was found to have the best in vitro inhibition activity against PTP1B (IC50 = 0.67 ± 0.09 µM) and the best selectivity (9-fold) between PTP1B and T-cell protein tyrosine phosphatase (TCPTP)
含有若丹宁-3-链烷酸基团的两个系列的1,3-二苯基-1H-吡唑衍生物被确定为竞争性蛋白酪氨酸磷酸酶1B(PTP1B)抑制剂。在研究的化合物中,发现IIIv对PTP1B具有最佳的体外抑制活性(IC50 = 0.67±0.09 µM),并且在PTP1B和T细胞蛋白酪氨酸磷酸酶(TCPTP)之间具有最佳选择性(9倍)。分子对接研究表明,化合物IIIm,IIIv和IVg可同时在催化位点和相邻的pTyr结合位点占据。这些结果为设计PTP1B和其他PTP抑制剂提供了新的先导化合物。
