生物活性:
Valerenic acid ((-)-Valerenic Acid), a sesquiterpenoid, is an orally active positive allosteric modulator of GABAA receptors. Valerenic acid is also a partial agonist of the 5-HT5a receptor. Valerenic acid mediates anxiolytic activity via GABAA receptors containing the β3 subunit. Valerenic acid also exhibits potent antioxidant properties.
体内研究:
Valerenic acid (1-6 mg/kg i.p. or 10 mg/kg p.o.) decreases the aversion of wild type mice to the lit area.Valerenic acid (10 mg/kg; p.o.) increases the proportion of time 129X1/SvJ mice spent onto the open arms.
体外研究:
Valerenic acid (1-100 μM) enhances the whole cell currents on GABAA receptors expressed in HEK 293 cells.Valerenic acid exhibits significant affinity for the 5-HT5a receptor, with an IC50 of 17.2 μM (Ki=10.7 μM).[3H]Valerenic acid binds to brain membranes reveals both a high affinity binding site (KD=25 nM) and a low affinity site (KD=16 μM).[3H]Valerenic acid is displaced by Valerenol with high potency (IC50=3 nM).
