Sorafenib-d₃ tosylate  (Synonyms: Donafenib tosylate; Bay 43-9006-d3 tosylate)

Sorafenib-d₃ (Donafenib-d₃) tosylate is the deuterium labeled Sorafenib (HY-10201). Sorafenib is a potent and orally active Raf inhibitor with IC50s of 6 nM and 20 nM for Raf-1 and B-Raf, respectively. Sorafenib-d3tosylate is a multikinase inhibitor with IC50s of 90 nM, 15 nM, 20 nM, 57 nM and 58 nM for VEGFR2, VEGFR3, PDGFRβ, FLT3 and c-Kit, respectively. Sorafenib-d3tosylate induces autophagy and apoptosis. Sorafenib-d3tosylate has anti-tumor activity. Sorafenib is a ferroptosis activator^[1].

2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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.
