摘要	Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) are vital class of drugs in treating HIV-1 infection, but drug resistance and toxicity drive the need for effective new inhibitors with potent antiviral activity, less toxicity and improved physicochemical properties. In the present study, twelve novel 1-(4-chlorophenyl)-2-(3,4-dihydroquinolin-1(2H)-yl)ethyl phenylcarbamate derivatives were designed as inhibitor of HIV-1 RT using the ligand based drug design approach and in-silico evaluated for drug-likeness properties. Designed compounds were synthesized, characterized and in-vitro evaluated for RT inhibitory activity against wild HIV-1 RT. Among these, four compounds (6b, 6i, 6j and 6l) exhibited significant inhibition of HIV-1 RT (IC50⩽20μM). Among four compounds, most active compounds 6b and 6j inhibited the RT activity with IC50 8.12 and 5.42μM respectively. Docking studies of compounds 6b and 6j were performed against wild HIV-1 RT in order to predict their putative binding mode with selected target. Further, cytotoxicity and anti-HIV activity of compounds 6b and 6j were evaluated on T lymphocytes (C8166 cells). All the synthesized compounds were also evaluated for antifungal activity against Candida albicans and Aspergillus niger fungal strains.
