PF 8380 is a potent autotaxin inhibitor (IC50 = 2.8 nM in isolated enzyme assay; 101 nM in human whole blood). Modulates lysophosphatidic acid (LPA) levels in vivo and in vitro by directly inhibiting autotaxin; reduces LPA levels both in plasma and at site of inflammation. Decreases leptin-induced MMP13 expression, in vitro. Orally available.

PF8380 was used to inhibit autotaxin in BV2 microglia cells in order to study the effect of ATX-LPA axis on microglia proinflammatory phenotype. Cells were treated with LPS (20ng/mi) in the absence or presence of the inhibitor (10µM) for 24 hours and then collected for RNA isolation and subsequent analysis of iNOS and TNFa expression with qPCR.
During preliminary studies we investigated whether the ATX inhibitor PF-8380 crosses the BBB and impacts LPA levels in the brain. After oral gavage of 3mg/kg PF-8380 per mouse (PF-8380 was dissolved in hydroxyl methyl cellulose), mice were anesthetized and perfused with PBS at different time points and the whole brains were dissected and immediately snap frozen in liquid nitrogen. Lipids were extracted using the Bligh & Dyer HCl method and the levels of LPA and PF-8380 were quantitated by LC-MS/MS.
