Rhamnocitrin
Based on 2 publication(s) in Google Scholar
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).

Biological Activity
Rhamnocitrin (40-80 μM; 48 h) significantly reduces apoptosis in serum deprivation-induced rat adrenal pheochromocytoma PC12 cells, and has no significant effect on STIM-1/Orai-1-mediated SOCE and downstream NFATc3 signaling[2].
Rhamnocitrin (0.1-10 μM; 24 h) inhibits the expression of IL-6, IL-8, MCP-1, ICAM-1, VCAM-1 and PAI-1 in a concentration-dependent manner in LPS-induced human umbilical vein endothelial cells (HUVECs) experiments, and inhibits STIM-1-mediated store-operated calcium entry (SOCE)[3].

Concentration:40 μM, 60 μM, 80 μM
-
Incubation Time:48 h
-
Result:Cell Viability: Dose-dependent increased in cell viability, with 60 μM and 80 μM groups significantly higher than the vehicle control.
Cell Apoptosis: Resulted a reduction in sub-G0/G1 phase cells (apoptotic cells) at 60 μM and 80 μM, indicating decreased apoptosis.
WB: Persistently attenuated of p38 MAPK, while increased ERK1/2 activation transiently at 60 μM.
