Derazantinib

**Semantic type:** Pharmacologic Substance

**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.

**Synonyms:** - ARQ 087 - ARQ-087 - DERAZANTINIB
