Various novel barbituric and thiobarbituricacidderivedsulphonamides were synthesized in excellent yield via three components single pot reaction; and these were screened for in vitro ureaseinhibitionstudies against jack bean urease. The compounds 1‐7 were found to exhibit a low to moderate activity whereas compounds 8‐14 showed a significant activity (88.3‐99.9% inhibition determined at 500 μM
1,3-Dicarbonyl derivatives of methylaminobenzene-sulfonamide were synthesized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA) I and hCA II were evaluated. hCA I and hCA II from human erythrocytes were purified by a simple one-step procedure by using Sepharose 4B-L-tyrosine-sulfanilamide affinity column. Our results show that the synthesized compounds inhibited the activity of carbonic anhydrase (CA) I and CA II. Among them, 2b and 2e were found to be the most active (IC50 = 2.12 and 2.52 mu M) for hCA I and hCA II, respectively.
