Abstract
The activities of the catalytic hydrolysis of phosphate diester (BNPP) [bis( p-nitrophenyl)phosphate diester] and plasmid DNA (pUC18) by mononuclear macrocyclic polyamine metal complexes have been investigated in this paper. The results showed that the highest activity in hydrolysis of BNPP was obtained with 1e–Zn(II) complex (composed of lipophilic group) as catalyst. The hydrolysis rate enhancement is up to 3.64 × 10 4 fold. These metal complexes could effectively promote the cleavage of plasmid DNA (pUC18) at physiological conditions.
