The invention provides novel compounds that are inhibitors of IAPs having the general formula: wherein X1, X2, X3, Y, A, R1, R2, R3, R4, R4′, R5, R5′, R6 and R6′ are as described herein. The compouds of the invention may be used to induce apoptosis in cells (or sensitise cells to apoptosis) in which IAPs are overexpressed or otherwise implicated in resistance to normal apoptotic processes. Accordingly, the compounds may be provided in pharmaceutically acceptable compositions and used for the treatment cancers.
本发明提供了一种新型化合物,其为IAPs
抑制剂,具有以下通式:
其中,X1、X2、X3、Y、A、R1、R2、R3、R4、R4'、R5、R5'、R6和R6'的含义如本文所述。本发明的化合物可用于诱导细胞凋亡(或使细胞对凋亡敏感),在其中IAPs过度表达或以其他方式参与对正常凋亡过程的抵抗。因此,这些化合物可以作为药学上可接受的组合物提供,并用于治疗癌症。
