Pamapimod-d4 (Ro4402257-d4) is the deuterium labeled Pamapimod. Pamapimod (Ro4402257) is a potent, selective and orally active p38 MAPK inhibitor with IC₅₀s of 14 nM and 480 nM and K_is of 1.3 nM and 120 nM for p38α and p38β, respectively. Pamapimod has no activity against p38δ or p38γ isoforms. Pamapimod has the potential for rheumatoid arthritis and other autoimmune diseases treatment^[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].
