Within this series of compounds, 4m is the most potent GPa inhibitor (IC(50)=2.68 microM), which is nearly 100 times more potent than the initial compound 1. Analysis of mapping between pharmacophores of different binding sites and each compound demonstrated that these benzamide derivatives bind at the dimer interface of the rabbit muscle enzyme, and possible docking modes of compound 4m were explored
设计,合成了一系列新颖的苯甲酰胺衍生物,并评估了它们从糖-1-磷酸中释放磷酸盐后对糖原磷酸化酶(GP)在糖原合成方向上的抑制活性。还介绍了这些化合物的构效关系(SAR)。在这一系列化合物中,4m是最有效的GPa抑制剂(IC(50)= 2.68 microM),其效力是初始化合物1的近100倍。分析不同结合位点的药效团与每种化合物之间的映射这些苯甲酰胺衍生物在兔肌肉酶的二聚体界面处结合,并通过分子对接模拟探索了化合物4m可能的对接模式。
