Alectinib-d₈  (Synonyms: CH5424802-d₈; RO5424802-d₈; AF802-d₈)

Alectinib-d₈ is the deuterium labeled Alectinib. Alectinib (CH5424802) is a potent, selective, and orally available ALK inhibitor with an IC50 of 1.9 nM and a Kd value of 2.4 nM (in an ATP-competitive manner), and also inhibits ALK F1174L and ALK R1275Q with IC50s of 1 nM and 3.5 nM, respectively[1]. Alectinib demonstrates effective central nervous system (CNS) penetration[2].

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].
