A novel series of benzoylsulfonamide derivatives were synthesized and biologically evaluated. Among them, 4-(biphenyl-4-ylmethylsulfanylmethyl)-N-(hexane-1-sulfonyl)benzamide (compound 18K) was identified as a protein tyrosine phosphatase 1B (PTP1B) inhibitor with potent and selective inhibitory activity against PTP1B (IC50=0.25 µM). Compound 18K functioned as a non-competitive inhibitor and bound
合成了一系列新颖的苯甲酰基磺酰胺衍生物,并对其进行了生物学评估。其中,4-(联苯基-4-基甲基硫烷基甲基)-N-(己烷-1-磺酰基)苯甲酰胺(化合物18K)被鉴定为对酪氨酸磷酸酶1B(PTP1B)有抑制作用的蛋白酪氨酸磷酸酶(IC50 = 0.25 µM)。化合物18K充当非竞争性抑制剂并与PTP1B的变构位点结合。它还在小鼠(最大药物浓度(Cmax)= 30,5 mg / kg时为45.5 µM),大鼠(Cmax = 30 mg / kg,Cmax = 53.6 µM)和小猎犬(10 mg / kg时Cmax = 37.8 µM)中具有较高的口服吸收率。公斤/天),并以30 mg / kg / d(每os(po))的血浆葡萄糖水平显着降低了一周,在db / db小鼠中没有副作用。综上所述,
