4-Hydroperoxy Cyclophosphamide-d 4 is the deuterium labeled 4-Hydroperoxy cyclophosphamide. 4-Hydroperoxy cyclophosphamide is the active metabolite form of the proagent Cyclophosphamide. 4-Hydroperoxy cyclophosphamide crosslinks DNA and induces T cell apoptosis independent of death receptor activation, but activates mitochondrial death pathways through production of reactive oxygen species (ROS). 4-Hydroperoxy cyclophosphamide has the potential for lymphomas and autoimmune disorders. 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
