    Melatonin (Melatonine, short for MT) is one of the hormones secreted by the pineal gland. Melatonin belongs to the indole heterocyclic compound, and its chemical name is N-acetyl-5 methoxytryptamine, also known as pineal gland, melatonin. The secretion of melatonin has an obvious circadian rhythm, the secretion is inhibited during the day, and the secretion is active at night.

    Melatonin can inhibit the hypothalamus-pituitary-gonad , reduce the contents of releasing hormone, gonadotro-pin, luteinizing -hormone and follicular estrogen, and can directly act on the gonads, reducing androgens, estrogen and The content of progesterone. In addition, MT has strong neuroendocrine and immunomodulatory activity and free radical scavenging antioxidant capacity, which may become a new method and approach for antiviral therapy. MT is finally metabolized in the liver, and damage to liver cells can affect the level of MT in the body.
