Anti-HIV diarylpyrimidine-quinolone hybrids and their mode of action

Bioorg Med Chem. 2015 Jul 1;23(13):3860-8. doi: 10.1016/j.bmc.2015.03.037. Epub 2015 Apr 6.

Abstract

A molecular hybridization approach is a powerful tool in the design of new molecules with improved affinity and efficacy. In this context, a series of diarylpyrimidine-quinolone hybrids were synthesized and evaluated against both wt HIV-1 and mutant viral strains. The most active hybrid 5a displayed an EC50 value of 0.28±0.07μM against HIV-1 IIIB. A couple of enzyme-based assays clearly pinpoint a RT-targeted mechanism of action. Docking studies revealed that these hybrids could be well located in the NNIBP of HIV-1 RT despite the bulky and polar properties of a quinolone 3-carboxylic acid moiety in the molecules.

Keywords: Anti-HIV; Diarylpyrimidine–quinolone hybrids; HIV-1 reverse transcriptase; Integrase.
