Synthesis, in vitro urease inhibitory potential and molecular docking study of benzofuran-based-thiazoldinone analogues

In continuation of our work on enzyme inhibition, the benzofuran-based-thiazoldinone analogues (1–14) were synthesized, characterized by HREI-MS, (1)H and (13)CNMR and evaluated for urease inhibition. Compounds 1–14 exhibited a varying degree of urease inhibitory activity with IC(50) values between 1.2 ± 0.01 to 23.50 ± 0.70 µM when compared with standard drug thiourea having IC(50) value 21.40 ± 0.21 µM. Compound 1, 3, 5 and 8 showed significant inhibitory effects with IC(50) values 1.2 ± 0.01, 2.20 ± 0.01, 1.40 ± 0.01 and 2.90 ± 0.01 µM respectively, better than the rest of the series. A structure activity relationship (SAR) of this series has been established based on electronic effects and position of different substituents present on phenyl ring. Molecular docking studies were performed to understand the binding interaction of the compounds.
