N6-(4-Hydroxybenzyl)adenosine is am endogenous compound extracted from G. elata for research interest for its potential sedative and hypnotic activity, as well as a neuroprotective and therapeutic agent for preventing and treating neurodegenerative disease.
N6-(4-Hydroxybenzyl) adenine riboside (NHBA) is an orally available and brain penetrant active active ingredient of Gastrodia elata rhizomes used for the treatment of insomnia. N6-(4-Hydroxybenzyl) adenine riboside is an adenosine A2A receptor and the equilibrative nucleoside transporter 1 (ENT1) agonist. It exhibits sedative and hypnotic effects by binding to adenosine A1 and A2A receptors in mice. N6-(4-Hydroxybenzyl) adenine riboside exerted a therapeutic effect on HD transgenic mouse by decreasing protein level of polyglutamine-expanded huntingtin in the striatum.
