Epimedin A (0.1-0.4 μM; 5 days) inhibits RANKL/M-CSF-induced osteoclast differentiation and reduces the mRNA expression of osteoclast-related genes in RAW264.7 cells. The mechanism involves the inhibition of the TRAF6/PI3K/AKT/NF-κB pathway[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:RAW264.7 cells treated RANKL and M-CSF
-
Concentration:0.1, 0.2 and 0.4 μM
-
Incubation Time:5 days
-
Result:Inhibited the mRNA levels of the osteoclast-related genes NFATc1, Ctsk, Oscar and Trap.
Epimedin A (5-20 mg/kg; oral administration; 11 days) exerts an anti-inflammatory effect in a mouse model of allergic contact dermatitis (CD)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Female Wistar rats (240±20 g, 10-12 weeks old) were ovariectomized to establish an osteoporosis model[1]
-
Dosage:5, 10 and 20 mg/kg
-
Administration:Oral administration; 90 days
-
Result:Increased bone density, relative bone volume, trabecular thickness and number, as well as reduced trabecular separation in the ovariectomized rats.
Dose-dependently normalized bone density and trabecular microarchitecture in the ovariectomized rats.
Inhibited the expression of TRAP and NFATc1 in the ovariectomized rats.
-
Animal Model:BALB/c mice aged 7 weeks old (20-25 g) treated DNFB to establish CD model[2]
-
Dosage:5, 10 and 20 mg/kg
-
Administration:Oral administration; 11 days
-
Result:Significantly and dose-dependently ameliorated DNFB-induced CD, as evidenced by repression of scratching behavior, dermatitis score, ear thickness and weight, and histopathological changes in ear tissues, as well as reduction of collagen fiber area percent.
Suppressed NF-κB/NLRP3 pathway, enhanced Nrf2/HO-1 pathway, reduced oxidative stress markers (MDA), increased antioxidant markers (GSH, SOD), inhibited pyroptosis-related molecules (NLRP3, ASC, caspase-1, 8, GSDMD, LDH), and decreased inflammatory cytokines (IL-1β, IL-6, TNF-α, IL-4, IFN-γ) and IgE levels (t-IgE, s-IgE, s-IgE/t-IgE ratio).

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 6.25 mg/mL (7.45 mM); Clear solution
This protocol yields a clear solution of ≥ 6.25 mg/mL (saturation unknown).
