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).

In Vitro

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[3]

Cell Line:

Human umbilical vein endothelial cells (HUVECs)
Concentration:

0.1 μM, 1 μM, 10 μM
Incubation Time:

24 h pretreatment + 6 h LPS stimulation
Result:

Dose-dependently reduced protein levels of ICAM-1, VCAM-1, and PAI-1 induced by LPS.
Significantly suppressed mRNA expressions of IL-6, IL-8, and MCP-1 at 1 μM and 10 μM.
Attenuated nuclear translocation of NFATc3, a downstream target of SOCE in a concentration-dependent manner.
Cell Viability**: No significant cytotoxicity was observed at concentrations ≤10 μM (CCK-8 assay).

Cell Viability Assay^[2]

Cell Line:

Rat pheochromocytoma PC12 cells
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.

In Vivo

After oral administration of 10 mL/kg A. complanatus extract (equivalent to 17.6 mg/kg Rhamnocitrin) to rats, collects blood (approximately 0.3 mL) at 0, 0.083, 0.167, 0.25, 0.333, 0.5, 0.75, 1, 2, 4, 6, 9, and 12 hours after administration from the ocular vein for analysis, under ether anesthesia. The results shows that the plasma concentration of Rhamnocitrin reached its maximum at 0.65 hours, with an average C_max of 29.57 ng/mL^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
