S-22153 (Cat No.: I009254) is a potent and selective antagonist of the melatonin MT1 and MT2 receptors, both of which regulate circadian rhythms and sleep–wake cycles. By blocking melatonin signaling, S-22153 has been used to investigate the physiological roles of melatonin in neuroendocrine regulation, sleep biology, and mood disorders. Its activity provides insights into receptor-mediated chronobiology and the therapeutic potential of targeting melatonin receptors. S-22153 is a valuable pharmacological tool for studying circadian rhythm modulation and melatonin-dependent pathways in neuroscience research.
