Biological Activity

Description Tivozanib is a potent and selective VEGFR inhibitor for VEGFR1/2/3 with IC50 of 30 nM/6.5 nM/15 nM, and also inhibits PDGFR and c-Kit, low activity observed against FGFR-1, Flt3, c-Met, EGFR and IGF-1R. Phase 3.

In vitro AV-951 is a novel quinoline-urea derivative. AV-951 blocks VEGF-dependent activation of mitogen-activated protein kinases and proliferation of endothelial cells. [1]
In vivo In vivo studies show that AV-951 also decreases the micro vessel density and suppresses VEGFR2 phosphorylation levels in tumor xenografts, especially at a concentration of 1mg/kg (p.o. administration). AV-951 shows almost complete inhibition of tumor xenografts growth (TGI>85%) in athymic rats. [1] Another study in rat peritoneal disseminated tumor model shows that AV-951 could prolong the survival of the tumor-bearing rats with the MST of 53.5 days. AV-951 displays antitumor activity against many human tumor xenografts including lung, breast, colon, ovarian, pancreas and prostate cancer. [2]

Protocol (from reference)

Kinase Assay:[1]
  • Kinase Assays

    Cell-free kinase assays are done in quadruplicate with 1 μM ATP to determine the IC50 values of AV-951 against a variety of recombinant receptor and nonreceptor tyrosine kinases including VEGFR1, VEGFR2, VEGFR3, c-Kit, PDGFRβ, Flt-3 and FGFR1.
Cell Assay:[1]
  • Cell lines

    Human umbilical vein endothelial cells (HUVEC) and normal human dermal fibroblasts

  • Concentrations

    1 μM

  • Incubation Time

    15 minutes

  • Method

    Human umbilical vein endothelial cells (HUVEC) and normal human dermal fibroblasts-based assays are done to determine the ability of AV-951 to inhibit ligand-dependent phosphorylation of tyrosine kinase receptors. The cells are starved overnight in appropriate basic medium containing 0.5% fetal bovine serum (FBS). The cells are incubated for 1 hour following the addition of AV-951 or 0.1% DMSO, and then stimulated with the cognate ligand at 37 °C. Receptor phosphorylation is induced for 5 minutes except for VEGFR3 (10 minutes), c-Met (10 minutes), and c-Kit (15 minutes). All the ligands used in the assays are human recombinant proteins, except for VEGF-C, a rat recombinant protein. Following cell lysis, receptors are immunoprecipitated with appropriate antibodies and subjected to immunoblotting with phosphotyrosine. Quantification of the blots and calculation of IC50 values are carried ou
