NOVEL SULFONAMIDE SCHIFF’S BASES AND THEIR ANTIMICROBIAL ACTIVITY

摘要

In the vision of chemistry, Schiff bases are excellent ligands and play a very important role in drug discovery and development. The Schiff bases and their complexes have been reported in the literature possessing wide applications in biological, clinical, and analytical fields. In outlook of this, new Schiff bases of Sulfonamide drug were synthesized by a very simple reaction and in good yield. The purity of the newly synthesized bases was confirmed by performing TLC in a suitable solvent system. The functional groups present in the targeted Schiff bases were confirmed by FT-IR spectroscopy. Further, all the synthesized compounds were successfully screened for their antimicrobial activity. Among these Schiff bases, the compound containing nitro and fluoro groups shows greater activity than standard drugs. By considering this, there is a need to design more analogs of sulfonamide Schiff bases and correlate the structural modifications with their respective antimicrobial activity to develop a Structure activity relationship.
