A novel method for synthesizing 1,2,4-triazole- and tetrazole-containing 4H-thiopyrano[2,3-b]quinolines using a new combination of the thio-Michael and aza-Morita–Baylis–Hillman reactions was developed. Target compounds were evaluated for their cytotoxicities and antiviral activities against influenza A/Puerto Rico/8/34 virus in MDCK cells. The compounds showed low toxicity and some exhibited moderate antiviral activity. Molecular docking identified the M2 channel and polymerase basic protein 2 as potential targets. We observed that the antiviral activity of thiopyrano[2,3-b]quinolines is notably affected by both the nature and position of the substituent within the tetrazole ring, as well as the substituent within the benzene moiety of quinoline. These findings contribute to the further search for new antiviral agents against influenza A viruses among derivatives of thiopyrano[2,3-b]quinoline.

This study presents an efficient method for the synthesis of condensed 3-aroyl-containing furan heterocycles, which are notable for their diverse biological activity, including antibacterial, antifungal, anti-inflammatory, and anticancer. The proposed method involves reaction of 1-aryl-3-bromo-3-nitropropenones with cyclic CH acids, yielding 3-aroyldihydrobenzofuran-4(5 H )-ones and 3-aroyl-4 H -furo[3,2- c ]- chromen-4-ones in excellent yields, providing a valuable approach for developing new biologically active compounds.
