A series of novel dinuclear macrocyclic polyamine La(III) complexes bearing multiethoxyl groups have been synthesized in this paper and their structures were characterized by 1H NMR, MS techniques and elemental analysis. The hydrolysis of bis(p-nitrophenyl)phosphate diester and the cleavage of plasmid DNA (pUC18) have been investigated by UV-visible spectrophotometric titration and the agarose gel electrophoresis. The results indicated that these La(III) complexes could effectively catalyze the hydrolysis of bis(p-nitrophenyl)phosphate diester and the cleavage of plasmid DNA (pUC18) under physiological conditions. The hydrolysis rate enhancement of bis(p-nitrophenyl)phosphate diester was up to 2.36×104 fold. The effects of the structure on the hydrolytic reactions were discussed.

Key words: dinuclear macrocyclic polyamine, complex, hydrolysis of bis(p-nitrophenyl)phosphate diester, DNA
