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 α-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.

Benzoyl urea derivatives that are alpha helical peptides mimetics that mimic BH3-only proteins, compositions containing them, their conjugation to cell-targeting-moieties, and their use in the regulation of cell death are disclosed. The benzoyl urea derivatives are capable of binding to and neutralizing pro-survival Bcl-2 proteins. Use of benzoyl urea derivatives in the treatment and/or prophylaxis of diseases or conditions associated with deregulation of cell death are also described.
