- CCR5 antagonists as anti-HIV-1 agents. 1. Synthesis and biological evaluation of 5-oxopyrrolidine-3-carboxamide derivatives
-
A novel lead compound, N-{3-[4-(4-fluorobenzoyl)piperidin-1-yl]propyl}-1- methyl-5-oxo-N-phenylpyrrolidine-3-carboxamide (1), was identified as a CCR5 antagonist by high-throughput screening using [125I]RANTES and CCR5-expressing CHO cells. The IC50 value of 1 was 1.9 μM. In an effort to improve the binding affinity of 1, a series of 5-oxopyrrolidine-3- carboxamides was synthesized. Introduction of 3,4-dichloro substituents to the central phenyl ring (10i, IC50=0.057 μM; 11b, IC 50=0.050 μM) or replacing the 1-methyl group of the 5-oxopyrrolidine moiety with a 1-benzyl group (12e, IC50=0.038 μM) was found to be effective for improving CCR5 affinity. Compound 10i, 11b, and 12e also inhibited CCR5-using HIV-1 envelope-mediated membrane fusion with IC50 values of 0.44, 0.19, and 0.49 μM, respectively.
