Synthesis, molecular docking, and biological evaluation of nitroimidazole derivatives as potent urease inhibitors

The objective of this study was to design new nitroimidazole-based derivatives as strong urease inhibitors for the treatment ofH. pylori infections. New series of nitroimidazole derivatives,4a –k, were synthesized by using TBTU as the catalyst and assayed as Jack bean urease inhibitors. The facile synthetic approach was employed for the preparation of targeted molecular designs in good to excellent yields, ranged from 65 to 92%. Accordingly, all the synthesized compounds,4a –k (IC50 = 1.43–7.72 μM), were more potent than the standard urease inhibitors, thiourea, and hydroxyurea. Among the derivatives,4d had the most urease inhibitor activity (IC50 = 1.43 μM), over 15-fold more potent than thiourea and 70-fold than hydroxyurea. True to form, the result of molecular docking studies was in good congruence with those obtained from in vitro tests.
