【Abstract】 Rare earth and tetracycline are all tumor-philic, rare earth tetracycline complexes have been used in the estimation of brain tumor and in the antitumor clinical tests. In order to increase the solubility of the rare earth tetracycline comples, we have tried to add a second ligand to the system to form the mixed ligand complex. In this paper, results of the determination of the stability constants of the mixed ligand complexes La-tetracycline-malic acid were reported.更多还原
