Abstract
A novel series of benzenesulfonamide derivatives of barbituric and thiobarbituric acids (2-12) were synthesized by condensation and cyclization reactions of various ureido and thioureido derivatives of sulfanilamides. Different substituents have been incorporated at C-5 of barbituric and thiobarbituric acid. Fluoro- and trifluoroacetyl substituents have been installed on various positions and their comparative biological screening was performed with the corresponding non-fluorinated analogs. The synthesized compounds were evaluated for their antimicrobial and antidiabetic activities. Some of the target compounds with fluorine substitution have shown very good antibacterial and antidiabetic activities. (C) 2012 Elsevier B.V. All rights reserved.
