In Vivo Humulone (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
