pyrrolo[3,4-c]pyrazol-6(1H)-ones were found to be potent p53-MDM2 inhibitors. Further optimization and structure–activity relationship studies were described in the present work. The result revealed that benzyl group on position N1 of imidazole and bromine on C4-phenyl of pyrrolidone showed higher inhibitory activities. In vitro antiproliferative assay demonstrated the potent p53-MDM2 inhibitor 5c with
在过去的十年中,小分子p53-MDM2蛋白与蛋白的相互作用已被证实是一种成功的癌症治疗策略。在我们以前的工作中,吡咯并[3,4-c]吡唑-6(1H)-是有效的p53-MDM2抑制剂。本工作描述了进一步的优化和构效关系研究。结果表明,咪唑的N1位上的苄基和吡咯烷酮的C4-苯基上的溴表现出更高的抑制活性。体外抗增殖试验表明,有效的p53-MDM2抑制剂5c对U2 OS和Saos-2细胞具有4倍的选择性。这些数据表明4,5-二氢吡咯并[3,4-c]吡唑-6(1H)-one部分是进一步开发p53-MDM2抑制剂的有价值的支架。
