Sulfonamides: X-Ray Structures and Biological Studies

Mr. Waqar Ahmad holds Master degree in Chemistry. His major areas of interest are synthesis of biologically active chemical compounds majorly sulfonamides.He is also the author of several articles published in reputed International Journals.

The use of antibiotics in the treatment of various infections of humans caused by microbes has been a great success. Over the past years there has been an increase in the resistance of microorganisms against a large number of drugs. Keeping in view the biological activity and medicinal importance of sulfonamides, new sulfonamides are being synthesized. This book describes the synthesis of N-benzyl-4-methylbenzenesulfonamide, its N-alkylated derivatives and evaluation of their anti-microbial activity. N-benzyl-4- methylbenzene sulfonamide was synthesized by the condensation of benzyl amine with p-toluene benzenesulfonylchloride. The solvent used for this reaction was water.N-alkylated derivatives were prepared by reacting N-benzyl-4-methylbenzenesulfonamide with different alkylating agents and sodium hydride using DMF as solvent. The synthesized compounds were characterized by different techniques like X-ray crystallography, FT-IR, Elemental analyzer and melting point. Evaluation of anti-microbial activity was carried out by employing deep well method against different bacterial strains.The synthesized compounds exhibited appreciable anti-microbial activity.
