Overview

In vitro study demonstrates that quercetin-3'-alpha-D-glucoside reduces neuroinflammation and oxidative stress in astroglial cells, indicating improved therapeutic potential over native quercetin.

Key Points

To evaluate and compare the anti-inflammatory and antioxidant properties of quercetin against its synthesized alpha-glucoside and natural beta-glucoside derivatives in an astroglial cell inflammation model.
Pretreated rat C6 astroglial cells for 2 hours with quercetin (Que), quercetin-3'-α-D-glucoside (Que-3α), or quercetin-3-β-D-glucoside (Que-3β) at concentrations of 15 µM and 30 µM.
Exposed the pretreated cells to lipopolysaccharide (LPS, 10 µg/mL) for 24 hours to induce inflammatory and oxidative stress pathways.
Assessed mitochondrial activity, reactive oxygen species (ROS) production, cell viability, rates of apoptosis and necrosis, and iNOS expression levels.
All evaluated compounds preserved astroglial mitochondrial activity following LPS exposure.
Que and Que-3α reduced LPS-induced ROS generation, improved cell viability, and decreased apoptosis and necrosis.
Que-3α down-regulated iNOS expression, demonstrating superior modulation of inflammatory mediators relative to the quercetin aglycone.
