led us to employ a structure based drug design procedure based on receptor-ligand pharmacophore generation protocol implemented in Discovery Studio 4.5 (DS 4.5). Subsequently, we collected 104 crystal structures of Pim-1 kinase from the Protein Data Bank (PDB) and used them to generate pharmacophores based on the anticipated co-crystallized ligand-Pim 1 kinase receptor interactions. All selected pharmacophoric
已经报道了在几种白血病和实体瘤中人磷脂酰肌醇甘露糖苷激酶同工型1(Pim-1激酶)的过度表达。我们对揭示神秘的Pim-1激酶结合袋的秘密性的持续兴趣使我们采用了基于结构的药物设计程序,该程序基于在Discovery Studio 4.5(DS 4.5)中实现的受体-配体药效团产生方案。随后,我们从蛋白质数据库(PDB)收集了104个Pim-1激酶晶体结构,并根据预期的共结晶的配体-Pim 1激酶受体相互作用,将其用于产生药效基团。列举了所有选择的药效学特征,并且仅保留了具有相应的有价值的受体-配体相互作用的那些。接下来,对所有药效团组合进行建模,并根据其接收者操作特征(ROC)曲线分析参数以及DS.4.5内置的遗传功能算法(GFA)验证模型对它们进行评分。因此,有111种药效基团具有可接受的ROC性能。最佳药效团是1XWS_2_04、2BIK_2_06和1XWS_2_06(ROC AUC值分别为:0
