series of (2-oxo-1,4-benzodiazepin-3-yl)-succinamides identified highly potentinhibitors of γ-secretase mediated signaling of Notch1/2/3/4 receptors. On the basis of its robust in vivo efficacy at tolerated doses in Notch driven leukemia and solid tumor xenograft models, 12 (BMS-906024) was selected as a candidate for clinical evaluation.
A Practical Approach for Enantio- and Diastereocontrol in the Synthesis of 2,3-Disubstituted Succinic Acid Esters: Synthesis of the pan-Notch Inhibitor BMS-906024
An oxidativeintermolecularenolateheterocoupling reaction was employed for the synthesis of anti-2,3-disubstituted succinic acid mono- and differentially protected diesters. Tactical approaches to access all the diastereomers are discussed. The method was applied to the synthesis of a potent anticancer agent, BMS-906024.
