Description and Uses

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].

An antioxidant compound found in Sicilian virgin olive oils and red wines.
