描述信息

A monocarboxylic acid that is 2-methylprop-2-enoic acid which is substituted at position 3 by a 3,7-dimethyl-2,4,5,6,7,7a-hexahydro-1H-inden-4-yl group. A bicyclic sesquiterpenoid constituent of the essential oil of the Valerian plant.
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[1][2][3].
