Synthesis, antimicrobial evaluation, and molecular docking studies of novel chromone based 1,2,3-triazoles

Abstract

In Search of novel antimicrobial agents with improved potency, we designed and synthesized a series of 3-((1-benzyl-1H-1,2,3-triazol-4-yl)methoxy)-2-(4-fluorophenyl)-4H-chromen-4-ones 5a–f using click chemistry. The structures of synthesized compounds were found using IR, 1H NMR, 13C NMR, and MS. All the synthesized compounds were assayed for their in vitro antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa and antifungal activity against Candida albicans, Candida glabrata, and Candida tropicalis by micro broth dilution method. The antimicrobial data suggested that from the series, compounds 3e, 4e, 5e, and 5f shows pronounced antimicrobial activity against the tested strain with low MIC value. Molecular docking study was used to rationalize binding interaction at the active site and the results showed good binding interaction.
