Dihydrocaffeic acid

Description

Dihydrocaffeic acid is a polyphenol that has diverse biological activities, including antioxidant, neuroprotective, and enzyme inhibitory properties. Dihydrocaffeic acid scavenges ABTS (; IC₅₀ = 81.86 μg/ml) and 2,2-diphenyl-1-picrylhydrazyl (DPPH; ; IC₅₀ = 192.86 μg/ml) radicals and increases the survival of RGC-5 mouse retinal ganglion cells under hypoxic conditions and in the presence of S-nitroso-N-acetyl-D,L-penicillamine (SNAP; ) in a concentration-dependent manner. It also decreases endothelial nitric oxide synthase (eNOS) activity in EA.hy926 human endothelial cells in a concentration-dependent manner. In vivo, dihydrocaffeic acid (30 mg/kg) decreases infarct size in a rat model of transient ischemia induced by middle cerebral artery occlusion (MCAO).

Uses

Dihydrocaffeic Acid is a natural product containing a catechol group with an α,β-unsaturated carboxylic acid chain. Dihydrocaffeic Acid has been shown to have hepatoprotective activity. Dihydrocaffei c Acid is a metabolite of Caffeic Acid (C08000) with potent antioxidant properties.

Uses

3-(3,4-Dihydroxyphenyl)propionic acid it can be used to produce 3-(3,4-dihydroxy-phenyl)-propionic acid octyl ester by heating.

Definition
