Biological Activity

Linifanib (ABT-869) is a potent multi-RTKs inhibitor of members of VEGFR and PDGFR families with IC50 of 4/3/3/14/4/66/190/170 nM for KDR/FLT1/CSF1R/KIT/FLT3/PDGFRβ/FLT4/Tie2, respectively.
Linifanib (ABT-869) shows much less active (IC50>10 uM) against other nonrelated tyrosine kinases, such as steroid receptor coactivator and EGFR.
Linifanib (ABT-869) inhibits RTK phosphorylation (IC50=2, 4, and 7 nM for PDGFRβ, KDR, and CSF-1R, respectively) and VEGF-stimulated proliferation (IC50=0.2 nM for human endothelial cells).
Linifanib (ABT-869) exhibits efficacy in human fibrosarcoma and breast, colon, and small cell lung carcinoma xenograft models (ED50=1.5-5 mg/kg, twice daily).
Linifanib (ABT-869) also is a small molecule inhibitor of necroptosis by targeting RIPK1 kinase
