  • (B and C) KMCH-1 cells were plated alone (monoculture) or together with PDGF-BB-secreting LX-2 cells (co-culture) in a transwell insert co-culture system (KMCH-1 cells in the bottom wells and LX-2 cells in the inserts; 1:1 ratio) for 2 days. Cells were treated as indicated with vehicle, rhTRAIL (10 ng/ml for 6 h on day 2), rhTRAIL plus imatinib [rhTRAIL:10 ng/ml for 6 h on day 2; Imatinib: 5 μmol/L for 24 h (day2)], or rhTRAIL plus linifanib [rhTRAIL: 10 ng/ml for 6 h on day 2; Linifanib:0.5 μmol/L for 24 h (day2)]. After rhTRAIL treatment for 6 h,KMCH-1 cells were analysed for apoptotic nuclear morphology by DAPI-staining (B) and for DNA fragmentation by transferasemediated dUTP nick end labelling assay (C) with quantification of apoptotic nuclei by fluorescence microscopy.

Biological Activity

Description Linifanib (ABT-869, AL39324, RG3635) is a novel, potent ATP-competitive VEGFR/PDGFR inhibitor for KDR, CSF-1R, Flt-1/3 and PDGFRβ with IC50 of 4 nM, 3 nM, 3 nM/4 nM and 66 nM respectively, mostly effective in mutant kinase-dependent cancer cells (i.e. FLT3).

In vitro

Linifanib shows inhibitory to Kit, PDGFRβ and Flt4 with IC50 of 14 nM, 66 nM and 190 nM in kinases assay. Linifanib also inhibits ligand-induced KDR, PDGFRβ, Kit, and CSF-1R phosphorylation with IC50 of 2 nM, 2 nM, 31 nM and 10 nM at cellular level and this cellular potency could be affected by serum protein. Linifanib suppresses VEGF-stimulated HUAEC proliferation with IC50 of 0.2 nM. While Linifanib has weak activity against tumor cells which are not induced by VEGF or PDGF, except for MV4-11 leukemia cells (with constitutively active form of Flt3) with IC50 of 4 nM. Linifanib could cause a decrease in S and G2-M phases with a corresponding increase in the sub-G0-G1 apoptotic population in MV4-11 cells. [1] Linifanib binds to the ATP-binding site of CSF-1R with Ki of 3 nM. [2] Linifanib (10 nM) exhibits a reduced phosphorylation of Akt at Ser473 and decreased phosphorylation of GSK3βat Ser9 in Ba/F3 FLT3 ITD cell lines. [3]

In vivo Linifanib (0.3 mg/kg) results in complete inhibition of KDR phosphorylation in lung tissue. Linifanib also inhibits the edema response with ED50 of 0.5 mg/kg. Linifanib (7.5 and 15 mg/kg, bid) significantly inhibits both bFGF- and VEGF-induced angiogenesis in the cornea. Linifanib inhibits tumor growth in flank xenograft models including HT1080, H526, MX-1 and DLD-1 with ED75 from 4.5-12 mg/kg. Linifanib also shows efficacy in A431 and MV4-11 xenografts at low dose levels. Linifanib (12.5 mg/kg bid) reveals a decrease of microvasculure density in MDA-231 xenograft. Linifanib shows a Cmax and AUC24 hours with 0.4 μg/mL and 2.7 μg•hour/mL in HT1080 fibrosarcoma model. [1]


Kinase Assay:[1]
- Collapse

Kinase assays:

Potencies (IC50 values) are determined by assays of active kinase domains cloned and expressed in baculovirus using the FastBacbaculovirus expression system or obtained commercially. For tyrosine kinase assays, a biotinylated peptide substrate containing a single tyrosine is used with 1 mM ATP, anEu-cryptate–labeled anti-phosphotyrosine antibody (PT66), and Strepavidin-APC in a homogeneous time-resolved fluorescence assay. Serine/threonine kinases are assayed using 5 μM ATP, [33P]ATP, and a biotinylated peptide substrate with peptide capture and incorporation of 33P determined using a SA-Flashplate. Linifanib is assayed at multiple concentrations prepared by serial dilution of a DMSO stock solution of Linifanib. The concentration resulting in 50% inhibition of activity is calculated using nonlinear regression analysis of the concentration response data.
