Apigenin enhances pentobarbital-induced sleep through chloride ion channel activation
Apigenin prolonged pentobarbital-induced sleep time in mice, similar to the GABA(A) receptor agonist muscimol. It also increased sleep rate and sleep time when combined with a sub-hypnotic dose of pentobarbital, and increased chloride influx in cultured cerebellar granule cells. Apigenin increased glutamate decarboxylase (GAD) expression but did not affect GABA(A) receptor subunit expression in the hippocampus.

Frequently Asked Questions
What is apigenin?▼
Apigenin is a natural flavonoid compound found in plants like chamomile, parsley, and celery, known for potential sedative and anxiolytic effects.
How does apigenin enhance sleep?▼
Apigenin enhances sleep by activating chloride ion channels, likely through GABA(A) receptors, increasing chloride influx and potentiating the effects of pentobarbital.
Is apigenin safe for human use?▼
This study was conducted in mice, so human safety and efficacy are not established. Apigenin is generally considered safe in dietary amounts, but high doses may have unknown effects.
Does apigenin affect GABA receptor expression?▼
No, apigenin did not affect the expression of GABA(A) receptor α-, β-, or γ-subunits in the mouse hippocampus, unlike pentobarbital.
