3D pharmacophore models for inhibitors of p53âMDM2 interaction were developed. The pharmacophore-based virtual screening of an in-house compound database combined with docking studies led to the identification of compound MCL0527 as a novel lead (MDM2 binding IC50 = 4.23 μM). Initial structure optimization yielded some derivatives with improved p53âMDM2 binding inhibitory activities. Furthermore, all target compounds showed potent anti-proliferative effect against human tumor cell lines with a generally selective profile on wild-type p53 cell lines.
针对p53-MDM2相互作用抑制剂的3D药效团模型已被开发出来。通过基于药效团的自家化合物数据库虚拟筛选与对接研究相结合,鉴定出了化合物MCL0527作为一种新型先导化合物(MDM2结合IC50 = 4.23 μM)。初步的结构优化获得了一些衍生物,它们具有更优的p53-MDM2结合抑制活性。此外,所有目标化合物均显示出对携带野生型p53的人类肿瘤细胞系具有强力的抗增殖效应,并表现出一般的选择性特征。
