Zinc-containing derivatives of 2-aminopyrimidine

A platform containing three anticancer components is proposed. The components are a radioactive ⁶⁹mZn isotope and zinc complexes, where both zinc and ligand exhibit anticancer properties. Two zinc-containing complexes, namely (2-AP)₂ZnCl₂ and (2-AP)₂Zn(Sal)₂ (AP is 2-aminopyrimidine, Sal is salicylate) were synthesized and characterized. Their cytotoxicity with respect to some leukemia cell lines is demonstrated. Their stability in physiological solution and percentage of apoptosis (by flow cytometry) are investigated. Stable complexes of compounds with the isotope ⁶⁹mZn were characterized by TLC and autoradiography.
