Isotope labelled Abemaciclib is a potent and selective inhibitor of cyclin-dependent kinases, CDK4 and CDK6, as a method to inhibit the proliferation of cancer cells. | [Biological Activity]
Abemaciclib-d8 (LY2835219-d8) is the deuterium labeled Abemaciclib. Abemaciclib (LY2835219) is a selective CDK4/6 inhibitor with IC50 values of 2 nM and 10 nM for CDK4 and CDK6, respectively.
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]. | [References]
