摘要：Based on the binding mode of our previously discovered dual inhibitor of Bcl-2 and Mcl-1, 3-thiomorpholin-8-oxo-8H-acenaphtho[1,2-b]pyrrole-9-carbonitrile (3, S1), a library of 9-substituted 3 derivatives was synthesized to further probe the p4 pocket of the two targets. By NMR, structure-activity relationship study, and site-directed mutation, compound 6d (3-(4-aminophenylthio)-8-oxo-8H-acenaphtho[1,2-b]pyrrole-9-3-phenyl)propylamine) was identified to span p2-p4 pockets of Mcl-1, Bcl-2 and Bcl-x(L), and then exhibited 9- to 35-fold better affinity to the three targets than 3 (IC50 = 10, 20 and 18 nM, respectively), which led to greater activity in induction of apoptosis in multiple cancer cell lines. Different contribution of p4 pocket to binding Bcl-2 and Mcl-1 was also investigated by plotting the potency and the HAC of the derivatives. (C) 2012 Elsevier Ltd. All rights reserved.
