Humulone (C09-1138-190)

Humulone (α-Lupulic acid), a prenylated phloroglucinol derivative, is a potent cyclooxygenase-2 (COX-2) inhibitor. Humulone acts as a positive modulator of GABA A receptor at low micromolar concentrations. Humulone is an inhibitor of bone resorption. Humulone possesses antioxidant, anti-angiogenic and apoptosis -inducing properties .In VitroHumulone (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. Humulone (0.1-10000 nM; for 12 h) suppresses the TNFα-induced increase of cyclooxygenase-2 mRNA. 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only.In VivoHumulone (10 or 20 mg/kg; IP; single dose) shortens sleep onset and increases the duration of sleep induced by pentobarbital and decreases the spontaneous locomotion in open field at 20 mg/kg. 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. 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Male BALB/cAnNRj mice (9-11 weeks of age)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.Form:Oil.
