Ethyl 3,4-dihydroxybenzoate Chemical Properties,Usage,Production
Description
Ethyl 3,4-dihydroxybenzoate (EDHB) is an analogue of 2-oxoglutarate and thus a competitive inhibitor of prolyl hydroxylase domain enzymes (PHDs). It is known as protocatechuic acid and is present in plant foods such as olives, roselle, du-zhong, and white grape wine.This compound have antioxidant, cardioprotective, neuroprotective, antimicrobial, anti-inflammatory and myoprotective activity, as well as anti-ulcer activity[1].
Chemical Properties
pale yellow to beige crystalline powder
Uses
An antioxidant compound found in Sicilian virgin olive oils and red wines.
Uses
The compound is a prolyl 4-hydroxylase inhibitor and can be used to protect the myocardium.
Definition
ChEBI: An ethyl ester resulting from the formal condensation of the carboxy group of 3,4-dihydroxybenzoic acid with ethanol. It is the anti-oxidative component of peanut seed testa.
Biological Activity
Ethyl 3,4-dihydroxybenzoate (EDHB) contains reducible polyphenol hydroxyl groups and exhibits antioxidant activity. Recent studies have shown that EDHB acts as an analog of the substrate α-ketoglutarate and competes for prolyl-hydroxylase activity, thus acting as an inhibitor and effectively inhibiting collagen synthesis and breast cancer metastasis. In addition, in vitro and animal studies in a cerebral ischemic rat model have revealed that EDHB shows increased protective effects and improves rat behavior by inhibiting free radical damage[2].
