Potent, specific, non-peptide small-molecule inhibitors of the MDM2-p53 interaction were successfully designed. The most potent inhibitor (MI-63) has a K(i) value of 3 nM binding to MDM2 and greater than 10,000-fold selectivity over Bcl-2/Bcl-xL proteins. MI-63 is highly effective in activation of p53 function and in inhibition of cell growth in cancer cells with wild-type p53 status. MI-63 has excellent specificity over cancer cells with deleted p53 and shows a minimal toxicity to normal cells.
成功设计出了高效、特异的MDM2-p53相互作用非肽小分子抑制剂。最有效的抑制剂（MI-63）与MDM2结合的K(i)值为3 nM，对Bcl-2/Bcl-xL蛋白的选择性超过10000倍。MI-63在激活p53功能以及抑制具有野生型p53状态的癌细胞生长方面非常有效。MI-63对p53缺失的癌细胞具有优异的特异性，对正常细胞的毒性极小。
