Deuruxolitinib phosphate

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into candidate compounds, primarily serving as quantitative tracers during the development process. Deuteration has attracted attention due to its potential to influence the pharmacokinetic and metabolic profiles of molecules^[1].
\nPotential advantages of deuterated compounds:
\n(1) Prolonged in vivo half-life. Deuterated compounds may improve the pharmacokinetic properties of the compound by extending its in vivo half-life. This can enhance the safety, efficacy, and tolerability of the compound, as well as increase the convenience of administration.
\n(2) Improved oral bioavailability. Deuterated compounds may reduce the extent of undesired metabolism (first-pass metabolism) in the intestinal wall and liver, allowing a larger proportion of unmetabolized drug to reach the target site of action. High bioavailability ensures activity at low doses and better tolerability.
