The present invention provides novel compounds, corresponding to formulae I and II, respectively, which are able to reactivate the apoptosis-inducing function of mutant p53 proteins. This reactivation is provided by restoration of sequence-specific DNA-binding activity and transcriptional transactivation function to mutant p53 proteins, and modulation of the conformation-dependent epitopes of the p53 protein. Accordingly, the substances according to the invention will be used in pharmaceutical compositions and methods for treatment of patients suffering from various types of tumors.
本发明提供了分别对应于式 I 和式 II 的新型化合物,它们能够重新激活突变 p53 蛋白的凋亡诱导功能。这种重新激活是通过恢复突变 p53 蛋白的序列特异性 DNA 结合活性和转录激活功能,以及调节 p53 蛋白的构象依赖性表位来实现的。因此,根据本发明的物质将用于治疗各类肿瘤患者的药物组合物和方法中。
