3-Thiomorpholin-8-oxo-8H-acenaphtho[1,2-b]pyrrole-9-carbonitrile (S1) based molecules as potent, dual inhibitors of B-cell lymphoma 2 (Bcl-2) and myeloid cell leukemia sequence 1 (Mcl-1): structure-based design and structure-activity relationship studies.

We recently described the discovery of a dual inhibitor of Bcl-2 and Mcl-1, 3-thiomorpholin-8-oxo-8H-acenaphtho[1,2-b]pyrrole-9-carbonitrile (3, S1). Here we report a structure-guided design in combination with structure-activity relationship studies to exploit the difference in the p2 binding pocket of Bcl-2 and Mcl-1, from which a novel dual inhibitor 3-(4-aminophenylthio)-8-oxo-8H-acenaphtho[1,2-b]pyrrole-9-carbonitrile (6h) was obtained, which showed significant enhanced IC(50) value against Mcl-1 (5 nM), greater Mcl-1/Bak disruption potential, and accordingly a 10-fold increased cytotoxicity over 3.
