Bioactivity of Fraxin
Description: Fraxin can be isolated from Acer tegmentosum, F. ornus and a. hippocastanum. It is a glycoside of fraxine [1] and has antioxidant, anti-inflammatory and anti metastasis activities. Fraxin exhibits antioxidant activity by inhibiting cyclic adenylate phosphodiesterase [2].
Target: cyclo AMP phosphodiesterase enzyme [2]
In Vitro Study: Fraxin (100 μ M) It has no cytotoxicity to Hep G2 cells. Fraxin at non cytotoxic concentrations significantly reduced t-BHP induced ROS production in a dose-dependent manner [1]. Fraxin (0.5 mm) can scavenge free radicals at high concentration and has cytoprotective effect on H2O2 mediated oxidative stress [2].
In vivo study: Fraxin (50 mg / kg, PO) significantly blocked CCl4 induced elevation of ALT and AST. Fraxin (10 and 50 mg / kg, PO) significantly reduced GSSG levels (1.7 ± 0.3 and 1.5 ± 0.2 nm / g liver, respectively) compared with GSSG levels in the CCl4 treated group
Reference:. Fraxin (50 mg/kg, p.o.) significantly blocks the CCl4-induced elevation of ALT and AST. Fraxin (10 and 50 mg/kg, p.o.) significantly reduces the GSSG levels (1.7±0.3 and 1.5±0.2 nM/g liver, respectively) compared with the GSSG levels of the CCl4-treated group[1].
