Rhamnocitrin
- CAS No.: 569-92-6
- Formula:C16H12O6
- Molecular Weight:300.26
IUPAC Name: 3,5-dihydroxy-2-(4-hydroxyphenyl)-7-methoxy-4H-chromen-4-one
InChIKey: MQSZRBPYXNEFHF-UHFFFAOYSA-N

Biological Activity: 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].
