Huisgen's [3+2] dipolar cycloaddition of 6-(azidomethyl)-5-chloro-2-(thiophen-2-yl)-7,8-dihydroquinoline 5 with various alkynes 6a-o using sodium ascorbate and copper sulphate gave new dihydroquinoline-1,2,3-triazoles 7a-o in good to excellent yields. The new compounds were evaluated for in vitro antimycobacterial against M. tuberculosis H37Rv (Mtb) and antiviral activity against influenza virus A/Puerto Rico/8/34 (H1N1). Among the fifteen new analogs, compounds 7a (MIC: 3.12 µg/mL), 7j and 7k (MIC: 6.25 µg/mL) were identified as potent antitubercular agents. The virus-inhibiting activity of all the fifteen compounds was found to be moderate, and among them the compound 7l, bearing thiophene moiety appeared the most active with good selectivity index (IC50 = 19.5 µg/mL; SI = 15). The results presented here will help developing newer dual inhibitors of tuberculosis and influenza virus.||URI:||https://cris.pasteurorg.ru/handle/123456789/244||ISSN:||0960-894X||DOI:||10.1016/j.bmcl.2019.07.040|
