Biological Activity

Description PF-8380 is a potent autotaxin (ATX) inhibitor with IC50 of 2.8 nM in an in vitro enzyme assay.
Targets
Autotaxin [1]
(Cell-free assay)
2.8 nM
In vitro PF-8380 inhibits rat autotaxin with an IC50 of 1.16 nM with FS-3 substrate. In human whole blood incubated with compound for 2 h autotaxin was inhibited with an IC50 of 101 nM[1].Inhibition of autotaxin by PF-8380 leads to decreased invasion, migtation and enhanced radiosensitization of GBM cells. Radiation-induced activation of Akt is abrogated by inhibition of ATX. Furthermore, inhibition of ATX leads to diminished tumor vascularity and delayed tumor growth[2].
In vivo Pre-treatment with PF-8380 prior to irradiation inhibited radiation-induced angiogenesis of tumor vascular endothelial cells and delayed progression of glioma tumor growth in vivo[2]. Oral administration of 30 mg/kg PF8380 reduces inflammatory hyperalgesia in a rat air pouch model, exhibiting >95% reduction of LPA levels in both plasma and inflammatory site tissue within 3 hours[1].

Protocol (from reference)

Cell Assay:[2]
  • Cell lines

    Mouse GL261 and Human U87-MG cells

  • Concentrations

    1 μM

  • Incubation Time

    45 min

  • Method

    GL261 or U87-MG cells are plated in triplicate onto 6 cm plates and allowed to grow to 70% confluence. The semi-confluent cell layer is scratched with a sterile 200 μL pipette tip to create a scratch devoid of cells and plates are washed once with PBS to remove non-adherent cells and debris. For radiosensitization drug studies, cells are treated with 1 μM PF-8380 or DMSO for 45 min prior to irradiation with 4 Gy, and then incubated at 37°C in 5% CO2. Control plates are monitored for cell migration (20–24 h). Cells are fixed with 70% ethanol and stained with 1% methylene blue. To quantify migration, cells in three randomly selected high power fields (HPFs) in the scratched area are counted and normalized for surrounding cell density.

Animal Study:[1]
  • Animal Models

    Male Lewis rats

  • Dosages

    1, 3, 10, 30, and 100 mg/kg

  • Administration

    by oral gavage
