Quercetin‐3‐O‐Glucuronide Alleviates Cognitive Deficit and Toxicity in Aβ1‐42‐Induced AD‐Like Mice and SH‐SY5Y Cells

Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) related imbalance, Tau-hyperphosphorylation, and neuroinflammation, in which Aβ and neuroinflammation can induce brain insulin resistance (IR). Gut microbiome disorder is correlated with inflammation in AD. As of yet, there are no effective treatments clinically. Thus, it is focused on the potential benefit of quercetin-3-O-glucuronide (Q3G), a pharmacologically active flavonol glucuronide, on AD treatment by regulating brain IR and the gut microbiome.
