Synthesis and antimicrobial activity of new metal [Mg(II), Fe(II), Co(II), Ni(II), Zn(II) and Cd(II)] complexes from 2-(1'/2'-hydroxynaphthyl)benzoxazoles have been described. Some of the metal complexes show significant antifungal activity (MIC <3.12 µg/ml). Further, 2-(1'/2'-hydroxynaphthyl)benzoxazoles exhibit excited-state intramolecular proton transfer mechanism that has been studied using absorbance and fluorescence spectroscopy.
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.
