A novel series of 3-acetamido-4-methyl benzoic acid derivatives designed on the basis of vHTS hit ZINC02765569 were synthesized and screened for PTP1B inhibitory activity. The most potent compounds 3-(1-(5-methoxy-1H-benzo[d]imidazol-2-ylthio)acetamido)-4-methyl benzoic acid (10c, IC50 8.2 μM) and 3-(2-(benzo[d]thiazol-2-ylthio)acetamido)-4-methyl benzoic acid (10e, IC50 8.3 μM) showed maximum PTP1B
合成了基于vHTS命中的ZINC02765569设计的一系列新的3-乙酰氨基-4-甲基苯甲酸衍生物,并筛选了其对PTP1B的抑制活性。最有效的化合物3-(1-(5-(1-甲氧基-1H-苯并[d]咪唑-2-基硫基]乙酰氨基))-4-甲基苯甲酸(10c,IC 50 8.2μM)和3-(2-(苯并[d]噻唑-2-基硫基)乙酰氨基)-4-甲基苯甲酸(10e,IC 50 8.3μM)显示最大的PTP1B抑制活性。还进行了对接研究,以了解控制PTP1B酶活性位点内设计分子的结合模式的相互作用的性质。
