Combretastatin A-4(CA-4)及其类似物具有良好的抗肿瘤和抗血管活性,引起了药物化学家的极大兴趣。本文利用分子对接模拟方法对与先导化合物具有相同结合模式的分子进行了识别,并利用基于分子对接的CoMFA方法建立了3D-QSAR模型。结果表明,所建立的QSAR模型具有较高的预测能力(CoMFA模型,q2 = 0.786,r2 = 0.988),且具有统计学意义。我们的模型可以提供帮助,以更好地理解这类化合物的结构-活性关系,也有利于设计具有良好的化学多样性的新型抑制剂。
Combretastatin A-4 (CA-4), its analogues and their excellent antitumoral and antivascular activities, have attracted considerable interest of medicinal chemists. In this article, a docking simulation was used to identify molecules having the same binding mode as the lead compound, and 3D-QSAR models had been built by using CoMFA based on docking. As a result, these studies indicated that the QSAR models were statistically significant with high predictabilities (CoMFA model, q2 = 0.786, r2 = 0.988). Our models may offer help to better comprehend the structure-activity relationships for this class of compounds and also facilitate the design of novel inhibitors with good chemical diversity.
