The catechol metabolites of estradiol, 2- and 4-hydroxyestradiol (2-OHE(2) and 4-OHE(2), respectively) are potent signaling molecules and are hypothesized to be central to estrogen-linked carcinogenes...
Redox and/or electrophilic metabolites formed during estrogen metabolism may play a role in estrogen carcinogenesis. 4-Hydroxyequilenin (4-OHEN) is the major phase I catechol metabolite of the equine ...
A suspension of tyrosinase-coated glass beads in butanol effectively oxidizes catechol substrate. The enzyme is not soluble in the organic solvent and activity can be stopped by removal of the solid s...
CGP 28014 (N-(2-pyridone-6-yl)-N',N'-di-n-propylformamidine) or its methanesulfonate salt CGP 28014 A was suspected to be a catechol-O-methyl-transferase (COMT) inhibitor because it was found to reduc...
