Autotaxin Inhibitor II, HA130

A thiazolidinedione that is designed to target the ATX active site thr210 with a boronic moiety and shown to potently inhibit ATX lysoPLD activity (IC₅₀ ~28 nM using recombinant human ATX or human plasma) in a reversible manner with a mixed-type Lineweaver-Burk kinetics. Reported to exhibit low cytotoxicity (TD₅₀ = 83, 105, and 2056 µM in HEK293T, A2058, and HepG2 cultures) and no activity toward NPP1, PDE, AP, or proteasomal chymotryptic/tryptic/caspase-like activities even at concentrations as high as 10 µM. Although HA130 quickly and effectively reduces circulating LPA level when injected in mice (463 µg/kg, i.v.) in vivo, the effect appears short-lived as is the case with S32826 (Cat. No. 189510).
