Phenytoin-15n2,13c

Phenytoin-15N2,13C is the 13C and 15N labeled Phenytoin[1]. Phenytoin (5,5-Diphenylhydantoin) is a potent Voltage-gated Na+ channels (VGSCs) blocker. Phenytoin has antiepileptic activity and reduces breast tumour growth and metastasis in mice[2][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].
