In this study, amino-oxy-diarylquinolines were designed using structure-guided molecular hybridization strategy and fusing of the pharmacophore templates of nevirapine (NVP), efavirenz (EFV), etravirine (ETV, TMC125) and rilpivirine (RPV, TMC278). The anti-HIV-1 reverse transcriptase (RT) activity was evaluated using standard ELISA method, and the cytotoxic activity was performed using MTT and XTT assays. The primary bioassay results indicated that 2-amino-4-oxy-diarylquinolines possess moderate inhibitory properties against HIV-1 RT. Molecular docking results showed that 2-amino-4-oxy-diarylquinolines 8(A-D): interacted with the Lys101 and His235 residue though hydrogen bonding and interacted with Tyr318 residue though π-π stacking in HIV-1 RT. Furthermore, 8A: and 8D: were the most potent anti-HIV agents among the designed and synthesized compounds, and their inhibition rates were 34.0% and 39.7% at 1 µM concentration. Interestingly, 8A: was highly cytotoxicity against MOLT-3 (acute lymphoblastic leukemia), with an IC50 of 4.63±0.62 µg/mL, which was similar with that in EFV and TMC278 (IC50 7.76±0.37 and 1.57±0.20 µg/ml, respectively). Therefore, these analogs of the synthesized compounds can serve as excellent bases for the development of new anti-HIV-1 agents in the near future.
