Catalytic transformations with copper-metalated diglycine conjugates Original Research Article

A series of copper-metalated, water-soluble bis-diglycine conjugates were synthesized and characterized through spectroscopic methods. These conjugates were evaluated for the cleavage of phosphodiester substrates, supercoiled plasmid relaxation in the presence of co-oxidants, and for the oxidation of a diphenolic substrate, 2,6-dimethoxyphenol. Appreciable rate enhancements were observed for these reactions and the oxidative nucleolytic cleavage activity and phenol oxidative coupling was presumably manifested via formation of reactive oxygen species.
