Kaempferol-3-o-β-d-glucuronate exhibit potential anti-inflammatory effect in LPS stimulated RAW 264.7 cells and mice model

Kaempferol-3-O-β-d-glucuronide (K3G) having various pharmacological effects was explored for its anti-inflammatory effect in LPS induced RAW 264.7 cells and mice model. K3G significantly inhibited various pro-inflammatory mediators like IL-1β, NO, PGE2, and LTB4. It upregulated the secretion of anti-inflammatory cytokine IL-10. K3G is found to reduce inflammation when studied for parameters like phagocytic index, carrageenan induced paw edema in mice and organ weight. It reduced inflammation in a dose dependent manner both in-vitro and in-vivo. Further molecular insights into the study reveal that K3G blocks the phosphorylation of NF-kB which is key regulator of inflammation, thereby exhibiting anti-inflammatory potential. Hence, this study permits further investigation to develop K3G as anti-inflammatory drug.
