Abstract
Synthesis of a small library of 1,4-disubstituted 1,2,3-triazoles containing benzofused N-heteroaromatic moieties was carried out through click reaction of various benzofused N-heteroaromatic alkynes with aromatic azides. All the synthesized compounds were characterized by spectroscopic techniques like IR, 1H NMR, 13C NMR, mass spectrometry and evaluated in vitro for antimicrobial activity against two Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus), one Gram-negative bacteria (Escherichia coli) and two fungi (Candida albicans, Aspergillus niger). Most of the synthesized 1,4-disubstituted 1,2,3-triazoles were found to possess significant antibacterial and antifungal activity against tested microbial species. Moreover, docking simulation of the compound 1-[(1-(4-nitrobenzyl)-1H-1,2,3-triazol-4-yl)methyl]-1H-benzo[d]imidazole was also carried out against E. coli topoisomerase II DNA gyrase B enzyme to study the binding modes and mechanism of action.
