PF8380

PF-8380 blocks inflammation-induced LPA synthesis. PF-8380 works both in vitro and in vivo through direct inhibition of autotaxin. In human whole blood PF-8380 inhibited autotaxin with an IC50 of 101 nM. Inhibition of ATX by PF-8380 led to decreased invasion and enhanced radiosensitization of GBM cells. Radiation-induced activation of Akt was abrogated by inhibition of ATX. Furthermore, inhibition of ATX led to diminished tumor vascularity and delayed tumor growth. PF-8380 can serve as a tool compound for elucidating LPA's role in inflammation.
