Ethyl 3,4-dihydroxybenzOATe 是从花生种子的种皮中发现的脯氨酰羟化酶抑制剂，是一种抗氧化剂。它是胶原蛋白合成抑制剂，具有骨骼保护作用。它通过激活 NO 合酶并产生线粒体ROS来保护心肌，可诱导 ESCC 细胞自噬和凋亡。

Ethyl 3,4-dihydroxybenzoate (EDHB): a prolyl hydroxylase inhibitor attenuates acute hypobaric hypoxia mediated vascular leakage in brain.

It is shown that DHB reversibly inhibits both morphological and biochemical differentiation of myoblasts, if it is added to the culture medium before the cell alignment stage.Along with the inhibition of procollagen synthesis, DHB also decreases markedly the production of a collagen-binding glycoprotein (gp46) present in the ER[1].

EDHB supplementation effectively scaled down HH induced cerebral edema with concomitant downregulation of brain NF-κB expression.?There was significant curtailment of pro-inflammatory cytokines and cell adhesion molecules.?There was significant downregulation of permeability factor VEGF by EDHB with concomitant increment in hypoxia inducible factor (HIF1α) and anti-inflammatory proteins HO-1 and MT-1 compared to HH control thus accentuating the potential of EDHB as effective hypoxic preconditioning agent in ameliorating HH mediated injury in brain[2].

Male Sprague-Dawley rats treated with EDHB (75 mg/kg for 3 days), were subjected to acute HH exposure at 9144 m (30,000 ft) for 5 h. Animals were assessed for transvascular leakage and edema formation in brain and role of key inflammatory markers along with hypoxia responsive genes.
