In this study, a series of thiophenyl-chalcones derivatives was synthesized and their DPPH ABTS activities were evaluated. All exhibited high antioxidant activity. Among them, 4e ((E)-5-(3-(4-(chlorosulfonyl)-3-hydroxyphenyl)-3-oxoprop-1-en-1-yl)thiophene-2-sulfonyl chloride) have higher activity (IC50 = 13.12 μM) than quercetin 15.49 μM), well-known as agent used standard. The structure-activi...

Sulphonamide motif is found extensively in numerous chemotherapeutic drug candidates, it acts by stopping the production of folate inside bacterial cell. Current research has established synthesis and characterization new bioprecursor prodrugs sulfadiazine. The first prodrug, 3, was synthesized via coupling diazonium salt sulfadiazine with ethyl acetoacetate AcONa at 0 °C. second sulfadiazine-p...

The low-activity sulphonamide resistant isozyme of carbonic anhydrase 111 has been shown to be skeletal-muscle-specific in man (Carter et al., 1979), and preliminary experiments have demonstrated high activities of the homologous molecule in rabbit, bovine, sheep, baboon, pig, chicken, rat and mouse muscle (Jeffery & Carter, 1980). Several years ago a sulphonamide(Diamox)-resistant isoenzyme of...
