electron-withdrawing groups (-Cl, -diCl, -F) for the design of novel compounds. CoMSIA, HBA, and HBD contour maps also suggested the requirement of functional groups (amide and hydrazide) for hydrogen bonding interactions. A total of 40 novel substituted benzamides were designed, and generated 3D-QSAR models were used for prediction of their activity prior to synthesis. ADMET prediction study was also carried
使用 3D-QSAR 分析设计新型取代苯甲酰胺,使用体外procaspase-3 激酶激活和 MTT 测定法合成和筛选。为了合理设计新型化合物,我们进行了 3D-QSAR 研究并生成了经统计验证的CoMFA(q 2 = 0.736,r 2 cv = 0.729)和 CoMSIA(q 2 = 0.751,r 2 cv = 0.716)模型。使用 CoMFA 和 CoMSIA 分析生成的等高线图表明,在设计新型化合物时需要空间体积大(芳香环)以及小的吸电子基团(-Cl、-diCl、-F)。CoMSIA、HBA 和 HBD等高线图还表明氢键相互作用需要官能团(酰胺和酰肼)。总共设计了 40 种新型取代苯甲酰胺,并使用生成的 3D-QSAR 模型在合成前预测它们的活性。还进行了ADMET预测研究,以选择更好的无毒化合物和更好的合成理化参数。最后,我们合成并表征了总共 10 种取代的苯甲酰胺
