Pyridinium bisretinoid A2E-d4 TFA is the deuterium-labeled Pyridinium bisretinoid A2E . Pyridinium bisretinoid A2E (A2E)is an initiator of blue-light-induced apoptosis. Photoactivation of Pyridinium bisretinoid A2E mediates autophagy and the production of reactive oxygen species.
Stable heavy isotopes of drogen, 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].
