1B (PTP1B), a key negative regulator of insulin signaling, is considered as a promising and validated therapeutic target for type 2 diabetes mellitus (T2DM) and obesity. Upon careful study, a series of 2-ethoxy-4-(methoxymethyl)benzamide and 2-ethoxy-5-(methoxymethyl)benzamide analogs designed by the “bioisosteric principle” were discovered, wherein their PTP1B inhibitory potency, type of PTP1B inhibition
酪氨酸磷酸酶1B(PTP1B)是胰岛素信号的关键负调节剂,被认为是2型糖尿病(T2DM)和肥胖症的有希望且经过验证的治疗靶标。经过仔细研究,发现了一系列根据“生物立体异构原理”设计的2-乙氧基-4-(甲氧基甲基)苯甲酰胺和2-乙氧基-5-(甲氧基甲基)苯甲酰胺类似物,其中它们对PTP1B的抑制力,对PTP1B抑制的类型,评价了选择性和膜渗透性。其中,化合物10m表现出高抑制活性(IC 50 = 0.07μM),对T细胞PTPase(TCPTP)的选择性(32倍)和良好的膜渗透性(P app = 2.41×10 -6 厘米/秒)。对细胞活力和细胞活性的进一步研究表明,化合物10m可以增强胰岛素刺激的葡萄糖摄取,而没有明显的细胞毒性。
