GtoPdb Ligand ID: 11830

Synonyms: CM-4307 | CM4307 | Sorafenib-d3 | Zepsun®
Compound class: Synthetic organic
Comment: Donafenib (CM-4307) is a deuterated derivative of the approved multikinase inhibitor sorafenib. Like sorafenib, it is orally active. Deuteration improves the stability of drug molecules thus extending half-life and increasing systemic exposure. This means that the effective drug dose may be shifted downward, with an associated improvement in tolerability. The medical formulation is donafenib tosylate.

Bioactivity Comments
We have been unable to find published potency data for donafenib at target kinases. However, its inhibitory activity is likely to be similar to that of sorafenib with IC50 values in the nM range against kinases including RAF1, BRAF, VEGFR2 and VEGFR3 [4].
