(MDM2)-p53 protein–protein interaction with small molecules has been shown to reactivate p53 and inhibit tumor growth. Here, we describe rational, structure-guided, design of novel isoindolinone-based MDM2 inhibitors. MDM2 X-ray crystallography, quantum mechanics ligand-based design, and metabolite identification all contributed toward the discovery of potent in vitro and in vivo inhibitors of the MDM2-p53
抑制小鼠双分钟 2 (MDM2)-p53 蛋白-蛋白与小分子的相互作用已被证明可以重新激活 p53 并抑制肿瘤生长。在这里,我们描述了基于异吲哚啉酮的新型 MDM2 抑制剂的合理的、结构指导的设计。 MDM2 X 射线晶体学、基于量子力学配体的设计和代谢物鉴定都有助于发现 MDM2-p53 与代表性化合物相互作用的有效体外和体内抑制剂,在 SJSA-1 骨肉瘤异种移植模型中诱导细胞停滞。 -每日口服给药。
