N-Desmethyl zopiclone-d8_product_DataBase

Bioactivity	N-Desmethyl zopiclone-d8 is deuterium labeled Norzopiclone. Norzopiclone is the inactive metabolite of Zopiclone. Norzopiclone has some anxiolytic properties.
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].
