Indole based thiadiazole derivatives (1–22) have synthesized, characterized by NMR and HREI-MS and evaluated for β-Glucuronidase inhibition. All compounds showed outstanding β-glucuronidase activity with IC50 values ranging between ± to ± µM when compared with standard d-saccharic acid 1,4 lactone (IC50 value of ± µM). | Indole bearing thiadiazole analogs Synthesis β-glucuronidase inhibition and molecular docking study
