Linifanib (ABT-869) is a structurally novel potent inhibitor of receptor tyrosine kinases (RTK) vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) with IC50 of 0.2 2 4 and 7 nM for human endothelial cells PDGF receptor beta (PDGFR-β) KDR and colony stimulating factor 1 receptor (CSF-1R) respectively. It has much less activity (IC50s > 1 μM) against unrelated RTKs soluble tyrosine kinases or serine/threonine kinases.
