Deuruxolitinib phosphate

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into candidate compounds, largely as tracers for quantitation during the development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of candidate compounds^[2].
Potential advantages of deuterated compounds:
(1) Extend the half-life in vivo. Deuterated compounds may be able to prolong the pharmacokinetic characteristics of the compound, that is, prolong the half-life in vivo. This can improve compound safety, efficacy and tolerability, and increase ease of administration.
(2) Improve oral bioavailability. Deuterated compounds may reduce the degree of unwanted metabolism (first-pass metabolism) in the gut wall and liver, allowing a greater proportion of the unmetabolized candidate compound to reach its target site of action. High bioavailability determines its activity at low doses and better tolerance.
(3) Improve metabolic characteristics. Deuterated compounds may reduce the formation of toxic or reactive metabolites and improve compound metabolism.
(4) Improve compound safety. Deuterated compounds may reduce or eliminate adverse side effects of candidate compounds and are safe.
(5) Preserve the therapeutic properties. Deuterated compounds are expected to retain similar biochemical potency and selectivity to hydrogen analogs in previous studies.
