Pentacosane-d52 is the deuterium labeled Pentacosane[1]. Pentacosane is one of the major components in the acetone extract from Curcuma raktakanda and is also in the essential oil from the leaves of Malus domestica. Pentacosane exhibit anti-cancer activities[2].
Stable heavy isotopes of drogen, 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].
