A series of novel 4,6-diarylpyrimidines (4,6-DAPY) and diarylbenzenes (DABE) compounds were synthesized and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). Among them, the most potent HIV-1 inhibitors were 8b, 8d, 14b and 18 (EC50 = 0.049, 0.381, 0.599 and 0.398 mu M, respectively), with HIV-1 inhibitory activity improved or similar to nevirapine (NVP, EC50 = 0.097 mu M) and delavirdine (DEV, EC50 = 0.55 mu M). The other compounds displayed moderate activity (8c, EC50 = 5.25 mu M) or were inactive (8a and 14a) against HIV-1 replication. Molecular modeling studies were performed with the synthesized compounds in complex with the wild-type reverse transcriptase (RT). A correlation was found between the anti-HIV activity and the electrostatic energy of interaction with Lys101 residue. These findings enrich the SAR of these Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) families. (C) 2012 Elsevier Masson SAS. All rights reserved.
