摘要

Nitration of 17β-estradiol by H2O2 and nitrite in the presence of various peroxidases, viz. horseradish peroxidase, lactoperoxidase, and peroxidase-containing homogenates from bovine uteri, was systematically investigated to assess on a chemical basis its potential relevance to the mechanisms of impairment of estrogen functions under oxidative/nitrosative stress conditions. In the presence of excess nitrite 17β-estradiol reacted smoothly to give 2 ...
