Humulone
Based on 1 Customer Validation
Humulone (α-Lupulic acid), a prenylated phloroglucinol derivative, is a potent cyclooxygenase-2 (COX-2) inhibitor. Humulone acts as a positive modulator of GABAA receptor at low micromolar concentrations. Humulone is an inhibitor of bone resorption. Humulone possesses antioxidant, anti-angiogenic and apoptosis-inducing properties.

COX-2 |
Humulone (0.1, 1, 10, 100, 1000, 10000 nM; for 12 h) with with 10 ng/ml TNFα dose-dependently decreases the amount of released PGE2 with an IC50 of about 30 nM in MC3T3-E1 cells. Humulone reduces cyclooxygenase activity of the TNFK-treated cells[1].
Humulone (0.1-10000 nM; for 12 h) suppresses the TNFα-induced increase of cyclooxygenase-2 mRNA[1].
Humulone hardly affects the cyclooxygenase-1 activity below 10 μM, whereas inhibits the cyclooxygenase-2 activity with an IC50 of about 1.6 μM in MC3T3-E1 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Humulone (10 μmol; applied topically to the dorsal shaved area) pre-treatment significantly inhibited TPA (10 nmol)-induced COX-2 expression in Female ICR mice (6-7 weeks of age) skin[3].
Humulone (1, 10 μmol; applied topical; pre-treatment 30 min) suppresses TPA-induced NF-κB DNA binding. Humulone attenuates TPA-stimulated nuclear translocation of p65 and p50 subunit proteins of NF-κB[3].

Animal Model:Male BALB/cAnNRj mice (9-11 weeks of age)[2]
-
Dosage:10 or 20 mg/kg
-
Administration:IP; pre-treatment before sodium pentobarbital (35 mg/kg; i.p.) and ethanol (3.5 g/kg)
-
Result:Significantly decreased the latency and prolonged the duration of sleep induced by pentobarbital at 20 mg/kg dose. These effects were not observed at a lower dose of 10 mg/kg.
Showed no effect on the onset of sleep induced by ethanol, but significantly increased sleep duration dose-dependently.

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: ≥ 2.5 mg/mL (6.90 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
