Biological Activity

Description PF-8380 is a potent autotaxin (ATX) inhibitor with IC50 of 2.8 nM in an in vitro enzyme assay.
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 Research:[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 Research:[1]
  • Animal Models: Male Lewis rats
  • Dosages: 1, 3, 10, 30, and 100 mg/kg
  • Administration: by oral gavage

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
