interactions between the nitro group in both compounds and the catalytic amino acid residues Arg 221 and Ser 216. Both compounds were evaluated for their in vivo antihyperglycemic activity in a type 2 diabetes mellitus rat model, showing significant lowering of plasma glucose concentration, during the 7 h post-intragastric administration.
2- arylsulfonylaminobenzothiazole衍生物1 - 27中使用一步反应来制备。评价了化合物对蛋白质酪氨酸磷酸酶1B(PTP-1B)的体外抑制活性。化合物4和16是PTP-1B的快速可逆(混合型)抑制剂,IC 50值在低微摩尔范围内。活性最高的化合物(4和16)停靠在PTP-1B的晶体结构中。对接结果表明,两种化合物中的硝基基团与催化氨基酸残基Arg 221和Ser 216之间潜在的氢键相互作用。在2型糖尿病大鼠模型中评估了这两种化合物的体内降血糖活性,显示血浆药物显着降低胃内给药后7小时内的葡萄糖浓度。
