Description

Application

PD 173074 has been used:

• to treat epithelial-mesenchymal transition (EMT)-induced cell lines in order to study its therapeutic use for head and neck squamous cell carcinoma (HNSCC)[1]
• in combination with PD0325901 to test whether an alternative downstream pathway for (fibroblast growth factor) FGF signalling is adopted during human hypoblast induction[2]
• to study its potential role in acute lymphoblastic leukaemia (ALL)-derived cell lines (TOM-1 and NALM-20)[3]

Biochem/physiol Actions

PD 173074 inhibitor is specific for receptor tyrosine kinases.[4] It competes with adenosine triphosphate (ATP) for its inhibition. PD 173074 prevents the FGF/ vascular endothelial growth factor (VEGF) induced angiogenesis.[5]

PD 173074 is a fibroblast growth factor receptor 3 (FGFR3) inhibitor: IC₅₀ = 5 nM inhibition of FGFR3 autophosphorylation. PD 173074 arrests the G₀/G₁ phase of FGFR3-expressing cells. It is 100-fold more selective for FGFR3 than for VEGF receptors, IGF-1 receptors, and MAPKs.

PD 173074 is a fibroblast growth factor receptor 3 inhibitor.
