Function

[B2CL1_HUMAN] Potent inhibitor of cell death. Inhibits activation of caspases (By similarity). Appears to regulate cell death by blocking the voltage-dependent anion channel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane. Also acts as a regulator of G2 checkpoint and progression to cytokinesis during mitosis.^[1] ^[2] Isoform Bcl-X(S) promotes apoptosis.^[3] ^[4]

Publication Abstract from PubMed

The BCL-2 family of proteins (including the prosurvival proteins BCL-2, BCL-XL, and MCL-1) is an important target for the development of novel anticancer therapeutics. Despite the challenges of targeting protein-protein interaction (PPI) interfaces with small molecules, a number of inhibitors (called BH3 mimetics) have entered the clinic and the BCL-2 inhibitor, ABT-199/venetoclax, is already proving transformative. For BCL-XL, new validated chemical series are desirable. Here, we outline the crystallography-guided development of a structurally distinct series of BCL-XL/BCL-2 inhibitors based on a benzoylurea scaffold, originally proposed as alpha-helix mimetics. We describe structure-guided exploration of a cryptic "p5" pocket identified in BCL-XL. This work yields novel inhibitors with submicromolar binding, with marked selectivity toward BCL-XL. Extension into the hydrophobic p2 pocket yielded the most potent inhibitor in the series, binding strongly to BCL-XL and BCL-2 (nanomolar-range half-maximal inhibitory concentration (IC50)) and displaying mechanism-based killing in cells engineered to depend on BCL-XL for survival.
