(±)-Epicatechin-¹³C₃  (Synonyms: 表儿茶素-¹³C₃)

(±)-Epicatechin-¹³C₃ is the ¹³C labeled (±)-Epicatechin. (-)-Epicatechin (HY-N0001) inhibits cyclooxygenase-1 (COX-1) with an IC50 of 3.2 μM. (-)-Epicatechin inhibits the IL-1β-induced expression of iNOS by blocking the nuclear localization of the p65 subunit of NF-κB[1].

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.
