Emergence of chloroquine (CQ) resistant Plasmodium falciparum strains necessitates discovery of inexpensive antimalarial drugs capable of targeting CQ-resistant strains. Towards this objective, herein we have synthesized and characterized naphthalene-Schiff bases or naphthalene-amine phenols. Among these compounds, 7 demonstrated a significant bioactivity with a half-maximal inhibitory concentration (IC(50)) of 1.7 microM against CQ-resistant Dd2 strains.
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.
