≥96% (HPLC), powder

Synonym: N-[2-[[4-(Diethylamino)butyl]amino-6-(3,5-dimethoxyphenyl)pyrido[2,3-d]pyrimidin-7-yl]-N′-(1,1-dimethylethyl)urea




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)
• in combination with PD0325901 to test whether an alternative downstream pathway for (fibroblast growth factor) FGF signalling is adopted during human hypoblast induction
• to study its potential role in acute lymphoblastic leukaemia (ALL)-derived cell lines (TOM-1 and NALM-20)

Biochem/physiol Actions

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

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.
