A NOVEL series of 1,4-benzoxazinone derivatives were synthesized and characterized using FT-IR , 1H-NMR, 13C-NMR and Mass spectroscopy. These compounds were in vitro screened against several bacterial species gram positive and gram negative as well as Candida albicans and found exhibiting moderate to potent activity. The antioxidant study was confirmed for the synthesized derivatives against 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical. Docking study for the potent compound 8 against glucosamine-6-phosphate synthase , the target enzyme for the antimicrobial agents was explored to explain the interactions of the discovered hits with in the amino acid residues of the enzyme active side. The docking parameters enhanced the activity of new compound as promising antimicrobial agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
