Clear solution
5%DMSO Corn oil
3.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 60 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Ramelteon (TAK-375) is a novel melatonin receptor agonist for human MT1 and MT2 receptors and chick forebrain melatonin receptors with Ki of 14 pM, 112 pM and 23.1 pM, respectively.
Targets
MT1 receptor [1]
(Cell-free assay)		 MT receptor (chicken) [1]
(Cell-free assay)		 MT2 receptor [1]
(Cell-free assay)
14 pM(Ki) 23.1 pM(Ki) 112 pM(Ki)
In vitro Ramelteon inhibits forskolin-stimulated cAMP production with IC50 of 21.2 pM in CHO cells. [1] Ramelteon has high affinity with recombinant human MT1 and MT2 receptors with pKi of 10.05 and 9.70, respectively. Ramelteon inhibits Xenopus laevis melanophore pigment granule aggregation with pEC50 of 11.48. [2] Ramelteon (1 nM) increases ERK1/2 phosphorylation not only in MT1/MT2 cerebellar granule cells but also in cerebellar granule cells expressing only one of the two melatonin receptors. 4P-PDOT blocks the stimulatory action of Ramelteon (1 nM) in MT1 KO cerebellar granule cells, while luzindole attenuates the action of Ramelteon (1 nM) in MT2 KO cerebellar granule cells. Ramelteon (100 μM) induces any pigment dispersion while melatonin completely disperses aggregated melanophores at 10 μM. [3]
In vivo Ramelteon (10 mg/kg, i/p) significantly reduces NREM sleep latency in rat and also produces a short-lasting increase in nonrapid eye movement (NREM) sleep duration, but the NREM power spectrum is unaltered. [2] Ramelteon (0.1 mg/kg and 1 mg/kg, p.o.) accelerates reentrainment of running wheel activity rhythm to the new lightdark cycle in rats without affecting learning or memory. [4] Ramelteon (0.03 mg/kg and 0.3 mg/kg, p.o.) significantly shortens latency to sleep onset and significantly increases total duration of sleep in freely moving monkeys without affecting the general behavior of the monkeys. [5]
Features A tricyclic synthetic analog of melatonin.
