Research Area: Cancer Biological Activity: Ramelteon is a melatonin receptor agonist with both high affinity for melatonin MT1 (IC50 =28.5 ± 8.55 pM)and MT2 (20.1 ± 9.25 pM)receptors and selectivity over the MT3 receptor. [1]The activity of ramelteon at the MT1 and MT2 receptors is believed to contribute to its sleep-promoting properties. Ramelteon has no appreciable affinity for the GABA receptor complex or for receptors that bind neuropeptides, cytokines, serotonin, dopamine, noradrenaline, acetylcholine, and opiates. [2] |
