Hydrolytic activity of (ZnZnII)-Zn-II and (ZnBaII)-Ba-II complexes toward tri(p-nitrophenyl) phosphate and di(p-nitrophenyl) phosphate: A functional model of heterobimetallic phosphodiesterase
Dinuclear hydroxo (ZnZnII)-Zn-II and (ZnBaII)-Ba-II core complexes, derived from a macrocyclic compartmental ligand, are examined in their hydrolytic activity toward tri(p-nitrophenyl) phosphate (TNP) and sodium di(p-nitrophenyl) phosphate (NaDNP) in aqueous DMSO. TNP is hydrolyzed by both complexes. On the other hand, DNP- is hydrolyzed by the ZnBa complex but not by the ZnZn complex.
