Research record
Overview
Compound name: Melatonin
Alternative names: N-acetyl-5-methoxytryptamine
Compound classification: Endogenous hormone; indoleamine
Brief factual description:
Melatonin is a naturally occurring hormone synthesized primarily by the pineal gland. It plays a central role in regulating circadian rhythms and sleep–wake timing and also exhibits antioxidant and neuroendocrine signaling properties.
Mechanism of Action
Primary biological targets: Melatonin receptors MT1 and MT2
Affected systems: Neurological, endocrine, circadian regulatory systems
Receptor selectivity: Selective activation of melatonin receptors involved in circadian signaling
Downstream signaling effects: Modulation of neuronal firing in the suprachiasmatic nucleus (SCN), reduction of alertness signaling, and synchronization of internal biological clocks.
