Design, synthesis, and bioactivity investigation of novel benzimidazole derivatives as potent urease inhibitors

Herein, we synthesized a series of novel benzimidazole derivatives 5a–k and screened their bioactivity as potent urease inhibitors. The structure of the 5a–k was elucidated using spectroscopic technics (1H-NMR, 13C-NMR, MS), elemental analysis, and melting point. The urease inhibition activity was evaluated using the urease enzyme inhibition kit. All 5a–k, except 5d, showed higher urease inhibition activity (0.77 to 6.25 µM) in comparison to...
