Crenolanib

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** An orally bioavailable benzimidazole targeting the platelet-derived growth factor receptor (PDGFR) subtypes alpha and beta and FMS-related tyrosine kinase 3 (Flt3), with potential antineoplastic activity. Upon oral administration, crenolanib binds to and inhibits both wild-type and mutated forms of PDGFR and Flt3, which may result in the inhibition of PDGFR- and Flt3-related signal transduction pathways. This results in inhibition of tumor angiogenesis and tumor cell proliferation in PDGFR and/or Flt3 overexpressing tumor cells. PDGFR and Flt3, class III receptor tyrosine kinases, are upregulated or mutated in many tumor cell types.
