| Bioactivity | Ramelteon metabolite M-II-d3 is the deuterium labeled Ramelteon metabolite M-II. Ramelteon metabolite M-II is the major metabolite of Ramelteon, with IC50s of 208 pM, 1470 pM for human melatonin receptors (MT1 or MT2). Ramelteon is a selective melatonin agonist[1][2]. | ||||||||||||
| Invitro | Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1]. | ||||||||||||
