3-Methylquinoxaline-2-carboxylic acid-d4 (MQCA-d4) is the deuterium labeled 3-Methyl-2-quinoxalinecarboxylic acid. 3-Methyl-2-quinoxalinecarboxylic acid (MQCA), an important N-oxide reductive metabolite of Quinocetone or Olaquindox, potently inhibits the growth of Chang liver cells through S phase arrest of the cell cycle^[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].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
