The interaction of coordinationally unsaturated 2,9-dimethylphenanthroline cobalt complex with adenine nucleotides

The study of complex formation between adenosine triphosphate (ATP) or adenosine diphosphate (ADP) and coordinationally unsaturated cobalt complex with 2, 9-dimethyl-o-phenanthroline (L) showed the possibility of formation of relatively stable mixed ligand complex CoL·ATP (log=4.45). The latter may be formed under the oxidative phosphorylation conditions in mitochondria. The presence of ATP in the complex provides the specific inhibition of the ATPase active center.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 4, pp. 744–748, April, 1994.
