2-Acetamidophenol-d 3

2-Acetamidophenol -d 3 (Orthocetamol-d 3 ) is the deuterium labeled 2-Acetamidophenol. 2-Acetamidophenol (Orthocetamol) is a regulator that targets ferroptosis and glutathione metabolic pathways, is the ortho-regioisomer of Paracetamol. 2-Acetamidophenol has anti-atherosclerotic activity, and inhibiting total cholesterol (TC) and triglyceride (TG) in a zebrafish hyperlipidemia model with IC50s for 30 μM and 40 μM, respectively. 2-Acetamidophenol upregulates the expression of glutathione synthesis-related genes (such as GCLC, GCLM, GSS) and iron ion transport genes (such as FPN1, FTH), reduces the accumulation of intracellular reactive oxygen species (ROS) and ferrous ions (Fe2+), and enhances the activity of glutathione peroxidase GPX4, thereby inhibiting macrophage phagocytosis of oxidized low-density lipoprotein (ox-LDL) and foam cell formation ^{[1] [2]}.

In Vitro, 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.
