Carbonyl–carbonyl (CO⋯CO) interactions are recently explored noncovalent interactions of significant interest owing to their role in the stability of biomacromolecules.
The phenoxy pendant isatins were observed to be highly potent inhibitors of acetylcholinesterase. In addition, the solid-state structure of a phenoxy pendant isatin showed an intriguing 1D-supramolecular self-assembled structure.
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.
