Abstract

Bcl-2 family proteins, which divides into pro-apoptosis proteins and anti-apoptosis proteins, are involved in cell apoptosis progression. As numerous studies illustrated, targeting Bcl-2 family proteins is more and more attractive and practicable to cancer treatment. In this work, we designed and synthesized a series of indomethacin derivatives as new inhibitors for Bcl-2 family proteins. Our results of binding assay to Bcl-2 proteins, MTT assay and apoptotic assay indicated that some compounds had potent binding affinity to Bcl-2/Mcl-1 but not Bcl-XL. Furthermore, compound 8j showed improved anti-proliferative activity than known Bcl-2 inhibitor WL-276.
