Metabolite Identification
Common Name4-O-Methylgallic acid
Description4-O-Methyl gallic acid (4-OMGA) has first been identified as a major methyl derivative of gallic acid in human plasma and urine. More recently, 4-O-methyl gallic acid (4-OMGA) has been found in urine during regular black tea ingestion and in plasma after moderate red wine consumption. PMID: 15527792 . 4-O-methylgallic acid (4-OMGA), a major metabolite of gallic acid abundant in red wine. 4-OMGA inhibited the expression of intercellular adhesion molecule-1(ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) stimulated with tumor necrosis factor-alpha (TNF-alpha), resulting in the suppression of leukocyte adhesion to HUVECs (PMID: 17027748 ). 4-O-Methyl gallic acid has been found to be a metabolite of Beauveria and Pantoea (PMID: 17111140 ) (https://www.researchgate.net/publication/275561863_Microbial_Degradation_of_Bergenin_a_Phenolic_C-Glucoside).
