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

Mcl-1 and Bcl-xL are crucial regulators of apoptosis, therefore dual inhibitors of both proteins could serve as promising new anticancer drugs. To design Mcl-1/Bcl-xL dual inhibitors, we performed structure-guided analyses of the corresponding selective Mcl-1 and Bcl-xL inhibitors. A co-crystal structure of a pyrazolo[1,5-a]pyridine derivative with Mcl-1 protein was successfully determined and revealed the protein-ligand binding mode. The key structure for Bcl-xL inhibition was further confirmed through the substructural analysis of ABT-263, a representative Bcl-xL/Bcl-2/Bcl-w inhibitor developed by Abbott Laboratories. Based on the structural data from this analysis, we designed hybrid compounds by tethering the Mcl-1 and Bcl-xL inhibitors together. The results of X-ray crystallographic analysis of hybrid compound 10 in complexes with both Mcl-1 and Bcl-xL demonstrated its binding mode with each protein. Following further optimization, compound 11 showed potent Mcl-1/Bcl-xL dual inhibitory activity (Mcl-1, IC50 = 0.088 muM; and Bcl-xL, IC50 = 0.0037 muM).
