Synthesis and DNA-Binding Properties of Bisdiazoliumylporphyrins. -The cationic porphyrins (I) are synthesized and their DNA-binding properties are investigated. Results show that porphyrin (Ia) intercalates between base pairs of DNA to stabilize the duplex DNA to thermal denaturation. -(TJAHJONO, DARYONO H.; YAMAMOTO, TOMOKO; ICHIMOTO,
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.
