PDB Ligand
Compound class: Synthetic organic
Comment: X-165 is a potent, selective, and bioavailable small molecule inhibitor of the LPA synthetic phosphodiesterase, autotaxin [1]. Autotaxin inhibitors are investigated for their anti-fibrotic potential, and X-165 was developed for potential to treat idiopathic pulmonary fibrosis (IPF). Analysis of autotaxin/X-165 complex crystals revealed that this compound binds to a site on the enzyme that is distinct from the binding site of exisiting inhibitors. Its binding pose shares some similarity with that of ziritaxestat (GLPG1690), but retains crucial differences.
