A novel class of small-molecule inhibitors of MDM2–p53 interaction with a (E)-3-benzylideneindolin-2-one scaffold was identified using an integrated virtual screening strategy that combined both pharmacophore- and structure-based approaches. The hit optimisation identified several compounds with more potent activity than the hit compound and the positive drug nutlin-3a, especially compound 1b, which
使用结合了药效团和基于结构的方法的集成虚拟筛选策略,鉴定了一类新型的MDM2-p53与(E)-3-苄叉二氮杂-2-酮骨架的小分子抑制剂。命中优化确定了几种比命中化合物和阳性药物nutlin-3a更有效的化合物,尤其是化合物1b,它们对MDM2的结合亲和力最高(K i = 0.093μM),对HCT116的抗增殖活性最强(野生型p53)细胞(GI 50 = 13.42μM)。另外,1b剂量依赖性抑制携带CT26结肠癌的BALB / c小鼠的肿瘤生长,没有明显的毒性迹象。总而言之,化合物1b代表了一种新的且有前途的先导结构,可用于开发抗癌药物MDM2–p53相互作用破坏剂。
