In this study, some new azomethine-triazole hybrids 5a–5l derived from N-benzoyl-L-phenylalanine were synthesized and characterized. The synthesized compounds showed first-rate, urease inhibition, and compounds 5c and 5e were found to be most effective inhibitors with 0.0137 ± 0.00082 μm and 0.0183 ± 0.00068 μm, respectively (thiourea 15.151 ± 1.27 μm). The kinetic mechanism of urease inhibition revealed the compounds 5c and 5e to be non-competitive inhibitors, whereas compounds 5d and 5j were found to be of mixed-type inhibitors. Docking studies also indicated better interaction patterns with urease enzyme. The results of enzyme inhibition, kinetic mechanism and molecular docking suggest that these compounds can serve as lead compounds in the design of more effective urease inhibitors. Synthesis of N-(1-(5-mercapto-4-((substituted benzylidene) amino)-4H-1, 2, 4-triazol-3-yl)-2-phenylethyl) benzamides as jack bean urease and free radical scavenger inhibitors. Kinetic mechanism revealed that most potent derivative 5j inhibits enzyme by non-competitive mechanism. The binding affinity of the molecules was evaluated using molecular docking studies. Based on the results of enzyme inhibition activities and molecular docking, it was inferred that these molecules can serve as template for the drug designing and discovery. Further structural modifications to most potent derivatives can lead to the designing of efficient enzyme inhibitors.
