Potent, Orally Bioavailable Diazabicyclic Small-Molecule Mimetics of Second Mitochondria-Derived Activator of Caspases
摘要:
A series of small-molecule Smac mimetics containing a diazabicyclic core structure have been designed, synthesized, and evaluated. The most potent compound (6) binds to XIAP, cIAP-1, and cIA-P-2 with K-i values of 8.4, 1.5, and 4.2 nM, respectively, directly antagonizes XIAP in a cell-free functional assay and induces cIAP-1 degradation in cancer cells. It inhibits cell growth with an IC50 value of 31 nM, effectively induces apoptosis in the MDA-MB-231 cancer cell line, and has a good oral bioavailability.
The invention relates to diazo bicyclic mimetics of Smac which function as inhibitors of Inhibitor of Apoptosis Proteins. The invention also relates to the use of these mimetics for inducing apoptotic cell death and for sensitizing cells to inducers of apoptosis.
