Twenty five 4, 6-dichlorobenzimidazole derivatives (1–25) have been synthesized and evaluated against β-glucuronidase inhibitory activity. The compounds which actively inhibitβ-glucuronidase activity have IC50 values ranging between 4.48 and 46.12 μM and showing better than standard d-saccharic acid 1,4 lactone (IC50 = 48.4 ± 1.25 μM). Molecular docking provided potential clues to identify interactions
