melatonin receptor

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.

Ramelteon (TAK-375) is a Melatonin Receptor Agonist. The mechanism of action of ramelteon is as a Melatonin Receptor Agonist.

4-P-PDOT (4-phenyl-2- propionamidotetralin) is a potent, selective and affinity Melatonin receptor (MT2) antagonist.

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.

N-ACETYLTRYPTAMINE is a partial agonist for melatonin receptors in the retina. Also used for determination of serotonin N-acetyl transferase.

Melatonin receptor agonist 1 (compound 20c) is a potent agonist of the melatonin receptor (MT) with Ki values of 108 nM for MT2 and 1140 nM for MT1 [1].

Nedemelteon is an agonist of the melatonin receptor (melatonin receptor).

Melatonin-Tamoxifen Conjugate (compound 16c) is an anticancer drug conjugate made of Melatonin and Tamoxifen, serving as an effective antagonist of ERα (IC50 = 863 nM). In cells expressing the hMT1 receptor, it binds to MLT receptors (Ki = 3.1 nM) and exhibits the ability to promote β-arrestin activation (EC50 = 914 nM) and ERK activation (EC50 = 98 nM). The IC50 values for Melatonin-Tamoxifen Conjugate in MCF-7, MDA-MB-231, and HT-1080 cell lines are 6.8 μM, 6.4 μM, and 1.7 μM, respectively.

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.

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.

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.

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

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

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

D-3263 hydrochloride (D3263 HCl salt) is enteric-coated, orally bioavailable transient receptor potential melatonin member 8 (TRPM8) agonist.

N-Acetyl-5-hydroxytryptamine (O-Demethylmelatonin) , also known as Normelatonin, is the immediate precursor of melatonin. It is produced from serotonin by the enzyme aralkylamine N-acetyltransferase and is converted to melatonin by acetylserotonin O-methyltransferase. It can potently activate TrkB receptor.

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.

D-3263 is an agonist of transient receptor potential melatonin member 8 (TRPM8) with potential antitumor activity.

Ramelteon metabolite M-II is the primary metabolite of Ramelteon and exhibits IC50 values of 208 pM and 1470 pM for human melatonin receptors (MT1 and MT2), respectively. Ramelteon itself is a selective melatonin receptor agonist.

6-Hydroxymelatonin is the main active metabolite and endogenous metabolite of Melatonin via CYP1A2, an agonist of MT2 receptor with antioxidant and neuroprotective effects, and effectively reduces KCN-induced lipid peroxidation and superoxide anion production.

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.

TIK-301 is a chlorinated melatonin derivative and a potent, high-affinity, and orally active melatonin MT1 and MT2 receptors agonist (Kis: 0.081 nM and 0.042 nM, respectively). TIK-301 is also a 5-HT2B 5-HT2C receptor antagonist with antidepressant action. TIK-301 has the potential for sleep disorders and other circadian rhythm disorders treatment.

MT2 melatonin receptor antagonist

GR 128107 is an antagonist of melatonin receptor.
