Zinc complexes of artificial histidine-containing dipeptides as catalysts of hydrolyses of p-nitrophenyl phosphates

Ichikawa, Kazuhiko,Uddin, M. Khabir,Nakata, Kou

, p. 115 - 116 (1999)

Zinc complexes of histidine-containing peptide derived from N,N′-dihistidylethylenediamine L1 and im-bzl-N,N″-dihistidyldiethylenetriamine L2 were designed and examined as catalysts for hydrolyses of bis(p-nitrophenyl)phosphate (BNPP) and p-nitrophenyl ph
