Isoquinoline-d7 is the deuterium labeled Isoquinoline[1]. Isoquinoline is an analog of pyridine. Isoquinoline structural-based alkaloids, such as tropoloisoquinoline, phthalideisoquinoline, and naphtlisoquinoline has 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].
