Synthesis and Biological Evaluation of Oxazine and Thiazine derivatives as Potent microbial agents

This study presents the synthesis and biological evaluation of oxazine and thiazine derivatives derived from chalcone as potential agents against microbial pathogens. The derivatives were synthesized by using reported methodology from chalcone. Chalcones, characterized by their α, β-unsaturated carbonyl system, exhibit various pharmacological activities such as anti-inflammatory, antioxidant, antimicrobial, anticancer, and antiviral effects. The chemical structures of the synthesized compounds were confirmed using spectroscopic techniques including FTIR. The antimicrobial activity of the synthesized oxazine and thiazine derivatives was evaluated against a panel of clinically relevant microorganisms, encompassing Bacillus subtilis and Escherichia coli. Preliminary results demonstrate that certain oxazine and thiazine derivatives exhibit significant antimicrobial activity, with some compounds displaying potent inhibition against a broad spectrum of microbial species. These findings suggest that oxazine and thiazine derivatives derived from chalcone hold promise as novel antimicrobial agents. Further optimization and preclinical investigations are warranted to fully explore their potential for clinical applications in combating microbial infections.
