7-Hydroxyindole (7-HI) is a compound that occurs naturally in both plants and animals. Derived from indole, an aromatic compound found in various plant and animal products, 7-Hydroxyindole holds significant importance as an intermediate in the synthesis of numerous compounds. The mechanism of action of 7-Hydroxyindole involves its interaction with specific receptors. It is believed to act as an agonist of the serotonin receptor 5-HT2A. Additionally, 7-Hydroxyindole is thought to act as an antagonist of the dopamine receptor D2, which contributes to the control of movement and reward-seeking behavior. Furthermore, it is believed to act as an agonist of the melatonin receptor MT1, involved in regulating sleep-wake cycles.
