Olsalazine-d₃ 

Olsalazine-d₃ is deuterated labeled Olsalazine (HY-B0174A). Olsalazine is a potent inhibitor of macrophages chemotaxis to LTB4 with an IC₅₀ value of 0.39 mM, also reduces the synthesis of 5-hydroxyeicosatetraenoic acid (5-HETE), 11-HETE, 12-HETE, and 15-HETE in polymorphonuclear leukocyte (PMNL) and mononuclear cells (MNL). Olsalazine can be used for researching ulcerative colitis. Anti-inflammatory activity^[1][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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
