6-Methylapigenin is a naturally occurring flavonoid and a derivative of apigenin. It has activity at GABAA receptors as a positive modulator.

Natural occurrence

6-Methylapigenin can be found in multiple plants, such as Valeriana officinalis, Valeriana jatamansi, and Picea neoveitchii.[1]

Biological activity

6-Methylapigenin binds to the GABAA receptor on the benzodiazepine binding site. This compound possesses anxiolytic effects. In a mouse model, it is also able to potentiate sleep induced by hesperidin, another flavonoid.[2][3] However, since it does not have the chemical structure of benzodiazepines, it can therefore be classed as a nonbenzodiazepine.
