Clarithromycin-d₃ 

Clarithromycin-d₃is the deuterium labeledClarithromycin(HY-17508)^[1]. Clarithromycin has a broad spectrum of antimicrobial activity. Clarithromycin inhibits the CYP3A4-catalyzed triazolam alpha-hydroxylation with the IC₅₀ (K_i) value of 56 (43) μM^[3]. Clarithromycin significantly inhibits the HERG potassium current^[4].Clarithromycin affects the autophagic flux by impairing the signaling pathway linking hERG1 and PI3K^[5].

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].
