Afzelechin

Description

Afzelechin is a flavan-3-ol, a type of flavonoid. It exists as at least 2 major epimers (afzelechin and epi-afzelechin). It is produced through the transformation of cis-3,4lecuopelargonidin through the action of (2R,3S)-catechin:NADP+ 4-oxidoreductase. Afzelechin can be found in many plants native to Asia such as: Astilbe rivularis (also known as waterside astilbe), Bergenia ligulate (also known as Paashaanbhed in Ayurveda traditional Indian medicine), and Wisteria floribunda (Japanese wisteria). Afzelechin also occurs in barley and rye as a member of the proanthocyanidins found in these crop plants. Afzelechin exhibits moderate inhibitory effects on tumor necrosis factor alpha (TNF-α) induced nuclear factor kappa-B (NF-kB) activation in HepG2 cells (PMID: 21985227 ). Afzelechin is only found in individuals who have consumed barley/rye or taken certain herbal medicines containing this compound.

Enzymes

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.
Gene Name:: UGT1A1
Uniprot ID:: P22309
Molecular weight:: 59590.91

Reactions

Afzelechin → 6-{[3,5-dihydroxy-2-(4-hydroxyphenyl)-3,4-dihydro-2H-1-benzopyran-7-yl]oxy}-3,4,5-trihydroxyoxane-2-carboxylic acid	details

Enzyme Details

2. Sulfotransferase 1A3

General function:: sulfotransferase activity
Specific function:: Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic monoamines (neurotransmitters such as dopamine, norepinephrine and serotonin) and phenolic and catechol drugs.
Gene Name:: SULT1A3
Uniprot ID:: P0DMM9
Molecular weight:: 34195.96

Reactions

Afzelechin → [4-(3,5,7-trihydroxy-3,4-dihydro-2H-1-benzopyran-2-yl)phenyl]oxidanesulfonic acid	details
