  • PubMed Abstract: 

    Herein we describe the discovery of A-1331852, a first-in-class orally active BCL-X L inhibitor that selectively and potently induces apoptosis in BCL-X L -dependent tumor cells. This molecule was generated by re-engineering our previously reported BCL-X L inhibitor A-1155463 using structure-based drug design. Key design elements included rigidification of the A-1155463 pharmacophore and introduction of sp 3 -rich moieties capable of generating highly productive interactions within the key P4 pocket of BCL-X L . A-1331852 has since been used as a critical tool molecule for further exploring BCL-2 family protein biology, while also representing an attractive entry into a drug discovery program.
