UMI-77-d₄ 

UMI-77-d₄ is the deuterium labeled UMI-77. UMI-77 is a selective Mcl-1 inhibitor, which shows high binding affinity to Mcl-1 (IC50=0.31 μM). UMI-77 binds to the BH3 binding groove of Mcl-1 with Ki of 490 nM, showing selectivity over other members of anti-apoptotic Bcl-2 members.

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].
