Abstract In the current era, a potent drug is still needed on market for treatment of various diseases worldwide. Researchers mainly focus those enzymes that cause these diseases. One major caused by an enzyme called urease, which increases concentration ammonia in body upon hydrolysis. across globe have keen interest to synthesize inhibitor this conversion. From perspective, hybrid analogs imidazopyridine and oxadiazole ( 1–20 ) were designed efficiently synthesized followed characterizing them through varied spectroscopic methods 1 HNMR, 13 CNMR, HREI-MS). addition, vitro analyses compounds conducted evaluate their anti-urease potency. There was significant potential most analyzed, but 15 , 16, 17 (IC 50 = 2.20 ± 0.10 μM, IC 2.50 2.30 2.10 respectively) performed exceptionally well comparison with thiourea 22.30 0.44 μM). The selected candidates further investigated under molecular docking study confirm protein ligand interactions. energy gap E HOMO–LUMO explored via density functional theory studies.
