Mechanism of action

From the NCI Drug Dictionary: An orally available multikinase inhibitor that targets Raf kinase and various receptor tyrosine kinases (RTKs), with potential antineoplastic activity. Upon oral administration, donafenib binds to and blocks the activity of Raf kinase, and inhibits Raf-mediated signal transduction pathways. This inhibits cell proliferation in Raf-expressing tumor cells. In addition, this agent may inhibit unidentified RTKs, and thus may further block tumor cell proliferation in susceptible tumor cells.
