Bacteria regulate their phenotype, growth and population via a signalling pathway known as quorum sensing. In this process, bacteria produce signalling molecules (autoinducers) to recognize their population density. Inhibiting this quorum sensing signalling pathway is one of the potential methods to treat bacterial infection. 2-Aminobenimdazoles are reported to be the strongest inhibitors of quorum sensing against wild-type P. aeruginosa. 1,2,3-Triazole based acyl homoserine lactones are found to be good inhibitors of the quorum sensing LasR receptor. Hence, in our current study, forty 1,2,3-triazole based 2-aminobenzimdazoles were synthesized and characterized using IR, NMR, MS and elemental analysis. A single crystal was developed for N-(1H-benzo[d]imidazol-2-yl)-2-(4-nonyl-1H-1,2,3-triazol-1-yl)acetamide (6d). All final compounds were screened for in vitro quorum sensing inhibitory activity against Pseudomonas aeruginosa. The quorum sensing inhibitory activity was determined in the LasR expressing P. aeruginosa MH602 reporter strain by measuring green fluorescent protein production. Among the title compounds, N-(1H-benzo[d]imidazol-2-yl)-2-(4-(4-chlorophenyl)-1H-1,2,3-triazol-1-yl)acetamide (6i) exhibited good quorum sensing inhibitory activity of 64.99% at 250 μM. N-(1H-Benzo[d]imidazol-2-yl)-2-(4-(4-nitrophenyl)-1H-1,2,3-triazol-1-yl)acetamide (6p) exhibited the most promising quorum sensing inhibitory activity with 68.23, 67.10 and 63.67% inhibition at 250, 125 and 62.5 μM, respectively. N-(1H-Benzo[d]imidazol-2-yl)-2-(4-(4-(trifluoromethyl)phenyl)-1H-1,2,3-triazol-1-yl)acetamide (6o) and N-(5,6-dimethyl-1H-benzo[d]imidazol-2-yl)-2-(4-(4-(trifluoromethyl)phenyl)-1H-1,2,3-triazol-1-yl)acetamide (7l) also exhibited 64.25% and 65.80% quorum sensing inhibition at 250 μM. Compound 6p, the most active quorum sensing inhibitor, also displayed low cytotoxicity at the tested concentrations (25, 50 and 100 μM) against normal human embryonic kidney cell lines. Finally, a docking study using Schrodinger Glide elucidated the possible putative binding mode of the significantly active compound 6p at the active site of the target LasR receptor (PDB ID: 2UV0).

A series of new isatin/triazole conjugates were designed based on the hypothesis that the ester-linked compounds could be enzymatically hydrolyzed by cellular esterases inside the cells. These compounds showed moderate to good growth inhibition toward the
