Melatonin Receptor

Melatonin (Melatonine) is a natural hormone secreted by the pineal gland that activates melatonin receptors. Melatonin is a hormone that regulates the biological clock and also has antioxidant and anti-inflammatory activities.

Melatonin D5, a deuterium-labeled version of melatonin, is a hormone produced by the pineal gland, known for its role as a selective ATF-6 inhibitor that promotes apoptosis in human hepatoma cells via COX-2 downregulation. Additionally, it activates melatonin receptors and exhibits antioxidative and anti-inflammatory properties.

Luzindole (N-0774) is a selective melatonin receptor antagonist that inhibits experimental autoimmune encephalomyelitis and exhibits antidepressant-like activity. It preferentially targets MT2 (Mel1b) over MT1 (Mel1a), with Ki values of 10.2 nM for human MT2 and 158 nM for MT1.

6-Chloromelatonin is a potent melatonin receptor agonist, a 5-methoxyindole compound that competes for presynaptic melatonin receptor sites in the rabbit retina, inhibiting the calcium-dependent release of [3H]dopamine with higher metabolic stability than melatonin. Chloromelatonin competitively binds to [3H]melatonin at MT2 receptors (pKi=9.77) and may be used to study insomnia and sleep disorders associated with depression.

8-M-PDOT (AH-002) is a selective and potent melatonin MT2 receptor agonist that also inhibits MT1 receptors. 8-M-PDOT exhibits anxiolytic activity and can be used to study MT2-induced neuropathic pain.

ACH-000143 have been identified as a novel agonist of the melatonin receptors MT1 and MT2.

Piromelatine is an agonist of melatonin MT1/MT2 receptors, 5-HT1A and 5-HT1D, and an antagonist of 5-HT2B.Piromelatine has antinociceptive activity with inhibitory effects on P2X3, TRPV1, and Nav1.7 channels, and can be used in studies of sleep-promoting, pain-relieving, anti-neurodegenerative, and antidepressant diseases. diseases, and can be used to improve memory deficits associated with chronic mild stress-induced lack of pleasure in rats.

UCM 608 (2-Phenylmelatonin) is an antagonist of melatonin-induced contractile responses at low concentrations and induces an increase in GDP-GTP exchange.

2-Iodomelatonin is a potent agonist of melatonin receptor 1 (MT1) with a Ki value of 28 pM, exhibiting over 5-fold selectivity for MT1 compared to MT2. It can be used to identify, characterize, and localize melatonin binding sites in the brain and peripheral tissues.

S26131 (N-[2-[7-[3-[8-(2-acetamidoethyl)naphthalen-2-yl]oxypropoxy]naphthalen-1-yl]ethyl]acetamide) behaves as an antagonist on MT1 and MT2 receptors with Ki of 0.5 and 112 nM respectively.

Tasimelteon (BMS-214778) is a melatonin receptor agonist that is used for the treatment of non-24 hour sleep-wake disorder in blind individuals.

Agomelatine (Valdoxan) is structurally closely related to melatonin. Agomelatine is a potent agonist at melatonin receptors and an antagonist at serotonin-2C (5-HT2C) receptors, tested in an animal model of depression.

Agomelatine hydrochloride (S-20098 hydrochloride) is a specific MT1 and MT2 receptor agonist with Ki values of 0.1 nM for CHO-hMT1, 0.06 nM for HEK-hMT1, 0.12 nM for CHO-hMT2, and 0.27 nM for HEK-hMT2, respectively [1]. Additionally, Agomelatine hydrochloride is a selective antagonist of the 5-HT2C receptor with pKi values of 6.4 and 6.2 for native (porcine) and cloned human 5-HT2C receptors, respectively [2].

Agomelatine (S-20098) L(+)-Tartaric acid is a specific agonist of MT1 and MT2 receptors (Kis: 0.1, 0.06, 0.12, and 0.27 nM for CHO-hMT1, HEK-hMT1, CHO-hMT2, and HEK-hMT2). It also is a selective 5-HT2C receptor antagonist (pKis: 6.4 and 6.2 at native (porcine) and cloned (human) 5-HT2C receptors).

GR 196429, a melatonin receptor agonist, exhibits selectivity for the MT1 subtype. This compound not only promotes sleep and alters circadian rhythms but also stimulates melatonin release in mice.
