A cyclic LPA analog that contains the 18:1 fatty acid, oleate, at the sn-1 position; at 25 μM, inhibits the transcellular migration of MM1 cells across mesothelial cell monolayers without affecting proliferation; at 0.1-1.0 μM, significantly inhibits autotaxin and antagonizes LPA1 (IC50 = 836 nM) and LPA3 (IC50 = 440 nM)
