Synthesis & Biological Evaluation of Oxime Based Derivatives as Antibacterial Agents

The rapid emergence of bacterial resistance to existing antibiotics has created an urgent need for new antimicrobial agents. Oxime-based compounds are recognized for their wide range of biological activities and structural versatility. In the present investigation, a series of novel oxime-based derivatives were synthesized and evaluated for their antibacterial potential. The compounds were prepared by the reaction of selected carbonyl compounds with hydroxylamine derivatives under controlled conditions. The synthesized products were purified and characterized using melting point, infrared spectroscopy, nuclear magnetic resonance, and mass spectrometry. The antibacterial activity of the synthesized oxime derivatives was assessed against selected Gram-positive and Gram-negative bacterial strains using standard in-vitro methods. Several derivatives demonstrated moderate to good antibacterial activity in comparison with standard drugs. Preliminary structure–activity relationship analysis revealed that substitution patterns on the aromatic ring significantly influenced antibacterial efficacy. These results indicate that oxime-based derivatives may serve as promising lead molecules for the development of new antibacterial agents.
