Abstract

Abstract: Tetra[4carboxymethoxyphenyl]porphyrin copper(Ⅱ), nickel(Ⅱ), zinc(Ⅱ) complex and their dibutyltin(Ⅳ) ester derivatives have been synthesized and characterized. The equilibrium constants of the aggregation of the metal porphyrin and the equilibrium constant of the π-π coordination with phenothoroline have been measured by using UVVis titration method. The results show that the equilibrium constants decrease in the order of K_CuP> K_NiP> K_ZnP. The vitro antitumor activities of the dibutyltin(Ⅳ) metal porphyrinate has some relation with the ability of aggregation and coordination with ligand of the metal porphyrin.

Key words: Tetra[4carboxymethoxyphenyl]porphyrin complex, Dibutyltin(Ⅳ), Vitro antitumor activity
