Melatonin is an indoleamine neurohormone found across plants and animals, produced endogenously from serotonin (5-HT) and secreted in animals as a regulatory signal for synchronization of the circadian rhythm and the sleep-wake cycle. The melatonin receptor system, consisting of the MEL-1A-R, MEL-1B-R, and MT3 subtypes, demonstrates particular plasticity and modularity – antagonists such as Luzindole and 2-Phenylmelatonin show modification of systemic responses to the Melatonin signal without impeding activation of the receptors by Melatonin. Powerful antioxidant activity is associated with Melatonin, and it is known to provide protection to lipids, proteins, and DNA against oxidative damage.
