Description : Ramelteon, a chronohypnotic, is an orally active and highly selective melatonin receptor (MT1, MT2 and MT3) agonist that preferentially binds to MT1 and MT2 receptors leading to potent inhibition of cAMP production in human cells expressing MT1 or MT2 receptors with the half maximal inhibition concentration IC50 values of 21.2 pM/L and 53.4 pM/L respectively [1].The s-configuration and ether group in the chemical structure of ramelteon confer its high affinity towards MT1 and MT2 receptors with the dissociation constant Ki values of 14 pM and 112 pM respectively in comparison with that of 2650 nM for MT3 receptors [1].Ramelteon has been found to potently promote sleep without causing any significant adverse effects leading to its application for the treatment of insomnia [1].References:[1] Miyamoto M.
