PLX-4720-d₇ 

PLX-4720-d₇ is the deuterium labeled PLX-4720. PLX-4720 is a potent and selective inhibitor of B-RafV600E with an IC50 of 13 nM in a cell-free assay, equally potent to c-Raf-1(Y340D and Y341D mutations), and 10-fold selectivity for B-RafV600E than wild-type B-Raf[1][2].

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].
