Summary: | Grapes has long been used for food, and reported as containing polyphenol which has antioxidant and anti-cancer effects. Neuroinflammation is chronic inflammation at the brain, lead to neurodegenerative diseases. In this study, quercetin-3-O-glucuronide (QG) isolated from the leaf of Vitis labruscana has anti-neuroinflammatory effects. QG were investigated using MTT assay, western blot, nitric oxide (NO) assay, prostaglandin $E_2$ ($PGE_2$) assay, cytokine assay in lipopolysaccharide (LPS)-induced inflammation in BV2 cells. QG dose-dependently attenuated the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), accordingly inhibited the production of NO and $PGE_2$. QG decreases the levels of proinflammatory cytokine such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interlukin-$1{\beta}$ (IL-$1{\beta}$). Thereby, QG may offer therapeutic potential for treatment of neurodegenerative disease related to neuroinflammation. |
