Niclosamide-¹³C₆  (Synonyms: 氯硝柳胺-¹³C₆; BAY2353-¹³C₆)

Niclosamide-¹³C₆ is the ¹³C₆ labeled Niclosamide. Niclosamide (BAY2353) is an orally bioavailable chlorinated salicylanilide, with anthelmintic and potential antineoplastic activity. Niclosamide (BAY2353) inhibits STAT3 with IC50 of 0.25 μM in HeLa cells and inhibits DNA replication in a cell-free assay.

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].

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