Recent advances in the development of Mcl-1 inhibitors for cancer therapy

Dysregulation of the mitochondrial apoptotic pathway controlled by members of the Bcl-2 protein family plays a central role in cancer development and resistance to conventional cytotoxic as well as targeted therapies. Hence, selective inhibition of pro-survival Bcl-2 family of proteins to activate apoptosis in malignant cells represents an exciting anti-cancer strategy. The remarkable clinical performance of the selective Bcl-2 antagonist venetoclax has highlighted the potential for selective inhibitors of the other pro-survival members of the Bcl-2 family, particularly Mc1-1. Here we review the latest progress on the discovery and development of selective inhibitors of Mc1-1 that are undergoing clinical evaluation for cancer therapy. (C) 2019 The Author(s).
