Tolcapone-d4 is the deuterium labeled Tolcapone. Tolcapone (Ro 40-7592) is a selective, orally active and powerful mixed (peripheral and central) COMT inhibitor with an IC50 of 773 nM in the liver[1]. Tolcapone is also a potent inhibitor of α-syn and Aβ42 oligomerization and fibrillogenesis[2]. Tolcapone induces oxidative stress leading to apoptosis and inhibition of tumor growth in neuroblastoma[3].
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].
