inhibitors are one of the best therapeutic targets for the identification of novel candidate drugs. Recent studies have shown some benzoquinazolines as potent antiviral agents and promising HAV-3C protease inhibitors. In the present study, a series of benzo[g]quinazolines (1–13) and their quinazoline analogues (14–17) were evaluated for their HCV-NS3/4A inhibitory activities using in vitro assay. Our

of 3‐substituted 2‐thioxo‐2,3‐dihydro‐1H‐benzo[g]quinazolin‐4‐ones 4a–e were synthesized from the reaction of 3‐aminonaphthalene‐2‐carboxylic acid 1 with isothiocyanate derivatives 2a–e. The alkylation of 4a–e with alkyl halides gave 3‐substituted 2‐alkylsulfanyl‐2,3‐dihydro‐1H‐benzo[g]quinazolin‐4‐ones 5a–o. S‐Glycosylation was carried out via the reaction of 4a–e with glycopyranosyl bromides 7a and

Flow cytometry was used to determine cancer-cell cycle distributions, and apoptosis was detected using annexin-V-FITC (V) and propidium iodide (PI) dyes. Fluorescence microscopy, in combination with Hoechst staining was used to detect DNA fragmentation. Most of the tested benzo[g]quinazolines demonstrated promising activity (IC50 = 8.8 ± 0.5–10.9 ± 0.9 μM) and (IC50 = 26.0 ± 2.5–40.4 ± 4.1 μM) against
