Metabolite Identification

Common Name

9-O-Methylcoumestrol

Description

9-O-Methylcoumestrol belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan. Thus, 9-O-methylcoumestrol is considered to be a flavonoid. 9-O-Methylcoumestrol has been detected, but not quantified in, several different foods, such as green tea, herbs and spices, red tea, herbal tea, and common peas (Pisum sativum). This could make 9-O-methylcoumestrol a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 9-O-Methylcoumestrol.

Chemical Taxonomy

Description

Belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan.

Enzyme Details

1. UDP-glucuronosyltransferase 1-1

General function:: Involved in transferase activity, transferring hexosyl groups
Specific function:: UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Is also able to catalyze the glucuronidation of 17beta-estradiol, 17alpha-ethinylestradiol, 1-hydroxypyrene, 4-methylumbelliferone, 1-naphthol, paranitrophenol, scopoletin, and umbelliferone.
