Abstract:
[Cu(Y)((G:2-6)-dendri-PAMAM-(Py)(n))](2Y+) complexes (3) were prepared, and their ability to generate oxygen radical anions was investigated. The maximum catalytic efficiency (k'(cat)/K(M)) was found to be 0.32 min(-1)·μM(-1), and a positive dendritic effect was observed. The saturated kinetics revealed that the improved catalytic efficiency resulted from an enhanced binding affinity toward molecular oxygen.
From The Clinical Editor:
In this basic science study, the oxygen radical anion generating ability of specific copper complex of a pyridine-modified poly(amidoamine) dendrimer was investigated and reported in details.
