Abstract
Thirty secnidazole derivatives have been synthesized and evaluated for Helicobacter pylori (H. Pylori) urease inhibitory activities and anti-inflammatory activities. All of them were reported for the first time. Their chemical structures were characterized by 1H NMR, 13C NMR, MS, and elemental analysis. Compound 5a, 6c and 8c showed the most potent urease inhibitory activities and anti-inflammatory activities with IC50 values of 1.7 μM, 1.0 μM, 2.0 μM and inhibition of 62.60%, 59.54%, 71.76%, respectively. Docking simulation was performed to position compound 6c into the urease active site to determine the probable binding model. Compound 5a, 6c and 8c with potent inhibitory activity against H. pylori may be potential antibacterial agents.
