A series of bromophenol derivatives were synthesized and evaluated as protein tyrosine phosphatase 1B (PTP1B) inhibitors in vitro and in vivo based on bromophenol 4e (IC50 = 2.42 μmol/L), which was isolated from red algae Rhodomela confervoides. The results showed that all of the synthesized compounds displayed weak to good PTP1B inhibition at tested concentration. Among them, highly brominated compound
合成了一系列溴酚衍生物,并基于溴酚4e(IC 50 = 2.42μmol / L)进行了体外和体内蛋白质酪氨酸磷酸酶1B(PTP1B)抑制剂的评价,该化合物是从红藻Rhodomela confervoides中分离得到的。结果表明,所有合成的化合物在测试浓度下均表现出从弱到良好的PTP1B抑制作用。其中,高度溴化的化合物4g对PTP1B表现出有希望的抑制活性,IC 50为0.68μmol/ L,比铅化合物4e的效力高约四倍。此外,化合物4g对其他PTP(TCPTP,LAR,SHP-1和SHP-2)具有很高的选择性。更重要的是,化合物4g的体内抗糖尿病活性研究也显示了令人鼓舞的结果。
