Rhamnocitrin

Rhamnocitrin is an anti-inflammatory and antioxidant agent that targets STIM-1, NFATc3 and MAPK pathways and can scavenge DPPH (IC50=28.38 mM) . Rhamnocitrin selectively inhibits oxidative stress and inflammatory responses in vascular endothelial cells and neurons. Rhamnocitrin up-regulates miR-185 to inhibit STIM-1-mediated store-operated calcium entry (SOCE), thereby blocking NFATc3 nuclear translocation and downstream inflammatory factor expression, while inducing heme oxygenase HO-1 expression and regulating the ERK/p38 MAPK pathway, inhibiting antioxidant and pro-inflammatory cytokines (such as IL-6, IL-8) and adhesion molecules (such as ICAM-1, VCAM-1) . Rhamnocitrin can be used in the study of endothelial-related inflammatory diseases (such as sepsis, acute lung injury, atherosclerosis) and neuroprotection (such as oxidative damage of PC12 cells) [1][2][3][4].
