GLPG-1690, an imidazopyridine derivative, has been found to be a ENPP2 protein inhibitor that could probably be effective as an anti-inflammatory agent and is under Phase II trial against Idiopathic pulmonary fibrosis.

Autotaxin is a circulating enzyme with a major role in the production of
lysophosphatic acid (LPA) species in blood. A role for the autotaxin/LPA axis has
been suggested in many disease areas including pulmonary fibrosis. Structural
modifications of the known autotaxin inhibitor lead compound 1, to attenuate hERG
inhibition, remove CYP3A4 time-dependent inhibition, and improve pharmacokinetic
properties, led to the identification of clinical candidate GLPG1690 (11).
Compound 11 was able to cause a sustained reduction of LPA levels in plasma in
vivo and was shown to be efficacious in a bleomycin-induced pulmonary fibrosis
model in mice and in reducing extracellular matrix deposition in the lung while
also reducing LPA 18:2 content in bronchoalveolar lavage fluid. Compound 11 is
currently being evaluated in an exploratory phase 2a study in idiopathic
pulmonary fibrosis patients.
