Common Name3,4,5-Trimethoxycinnamic acid
Description3, 4, 5-Trimethoxycinnamic acid is a methoxycinnamic acid with three methoxy substituents at the 3-, 4- and 5-positions. It has a role as an allergen. It is a conjugate acid of a 3,4,5-trimethoxycinnamate. 3, 4, 5-Trimethoxycinnamic acid is an organic acid found in normal human urine (PMID: 6992730 , 6511847 ). Trimethoxycinnamate is a natural aromatic ester from Piper longum that inhibits expression of cell adhesion molecules on endothelial cells (TNF- -induced expression of intercellular adhesion molecule-1 (ICAM-1) and E-Selectin and vascular adhesion molecules-1 (VCAM-1)), without being toxic to endothelial cells. (PMID: 16313198 ).
