ACENAPHTHO HETEROCYCLIC COMPOUND AND APPLICATION THEREOF

The present invention relates to acenaphtho heterocyclic compounds and their uses in manufacturing the BH3 mimetics as Bcl-2-like protein inhibitors. Structures are shown in the following: Statistical analysis of their bio-activities showed these compound

3-Thiomorpholin-8-oxo-8H-acenaphtho [1,2-b] pyrrole-9-carbonitrile (S1) derivatives as pan-Bcl-2-inhibitors of Bcl-2, Bcl-xL and Mcl-1

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-xL, and then exhibited 9- to 35-fold better affinity to the three targets than 3 (IC 50 = 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.

3-Thiomorpholin-8-oxo-8 h -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 IC50 value against Mcl-1 (5 nM), greater Mcl-1/Bak disruption potential, and accordingly a 10-fold increased cytotoxicity over 3.
