NCIt definition : An orally bioavailable inhibitor of the fibroblast growth factor receptor (FGFR) with
potential antineoplastic activity. Derazantinib binds to and potently inhibits the
activity of FGFR subtypes 1, 2 and 3. This may result in the inhibition of FGFR-mediated
signal transduction pathways, tumor cell proliferation, tumor angiogenesis and tumor
cell death in FGFR-overexpressing tumor cells. FGFR, a receptor tyrosine kinase, is
upregulated in many tumor cell types and plays a key role in tumor cellular proliferation,
differentiation, angiogenesis and survival.;
