STUDY ON THE STABILITY AND STACKING INTERACTION EFFECT OF THE TERNARY M(Ⅱ)(ATP) AND PYRIDINE-LIKE LIGANDS

Received Date: 17 August 1993

Fund Project: this work was supported by the National Natural Science Foundation of China.

The stabilities of the complexes of three pyridine-like ligands with M(Ⅱ)(ATP)^2- and M(Ⅱ)(M=Ni, Co) were studied by spectrophotometry and by comparing the stability constants of the ternary complexes with those of the binary complexes. A stacking interaction between the pyridine ring and the purine ring of ATP is indicated. The general existence of the stacking interaction encourages us to interpret the antitumor mechanism of a new class of antitumor drugs.
