which are belong to thiourea class, showed good inhibition. Their kinetics study and cytotoxicity profiles showed all type of inhibition except uncompetitive-type inhibition and no cytotoxicity except few compounds. Competitive type of inhibitors could inhibit other α-chymotrypsin-like serine proteases, which are therapeutics target.

Thiourea derivatives (1–38) were synthesized and evaluated for their urease inhibition potential. The synthetic compounds showed a varying degree of in vitro urease inhibition with IC50 values 5.53 ± 0.02–91.50 ± 0.08 μM, most of which are superior to the standard thiourea (IC50 = 21.00 ± 0.11 μM). In order to ensure the mode of inhibition of these compounds, the kinetic study of the most active compounds
have been prepared. The structure of these thiazolidones was confirmed by studying their hydrolysis products. Some of these thiazolidones were screened for their fungicidal activity against Aspergillus niger by agar-growth method and found to be more appropriately fungistatic and not fungicidal.
