Tasimelteon

Synonyms: BMS 214778, VEC 162

Tasimelteon (BMS 214778, VEC 162) is a selective dual melatonin receptor (MT1/MT2) agonist with 2.1-4.4 times greater affinity for the MT2 receptor believed to mediate circadian rhythm phase-shifting (Ki = 0.0692 nM and Ki = 0.17 nM in NIH-3T3 and CHOeK1 cells, respectively), than for the MT1 receptor (Ki = 0.304 nM and Ki = 0.35 nM, respectively).

Biological Activity

Description Tasimelteon (BMS 214778, VEC 162) is a selective dual melatonin receptor (MT1/MT2) agonist with 2.1-4.4 times greater affinity for the MT2 receptor believed to mediate circadian rhythm phase-shifting (Ki = 0.0692 nM and Ki = 0.17 nM in NIH-3T3 and CHOeK1 cells, respectively), than for the MT1 receptor (Ki = 0.304 nM and Ki = 0.35 nM, respectively).
Targets
MT2 receptor [1] MT1 receptor [1]
9.8(pKi) 9.45(pKi)
In vitro
In vitro Tasimelteon is a circadian regulator that resets the master clock in the suprachiasmatic nuclei of the hypothalamus by binding to both melatonin MT1 and MT2 receptors making it a dual melatonin receptor agonist[3]. The affinity of tasimelteon for the MT2 receptor is 4-fold higher than its affinity for the MT1 receptor[2].
In Vivo
In vivo In rats and monkeys, the half-life of tasimelteon was approximately 2 h which is longer than the half-life of melatonin[1]. Tasimelteon has a mean absolute bioavailability of approximately 38.3%. The higher oral-to-IV exposure ratios and decrease in the metabolite-to-parent ratios after IV administration for tasimelteon's metabolites indicate that although tasimelteon is subject to first-pass metabolism, a substantial fraction of its metabolism occurs post- rather than presystemically. Both oral and IV tasimelteon were well tolerated[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
