Linifanib (ABT-869) is a potent and orally active multi-target inhibitor of VEGFR and PDGFR family with IC50s of 4, 3, 66, and 4 nM for KDR, FLT1, PDGFRβ, and FLT3, respectively. Linifanib shows prominent antitumor activity. Linifanib has much less activity against unrelated RTKs, soluble tyrosine kinases, or serine/threonine kinases. Linifanib is a specific miR-10b inhibitor that blocks miR-10b biogenesis.
