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.
