EL244

EL244 is an inhibitor of Autotaxin (ATX) with an IC50 of 50 nM and an agonist of PPARγ with an IC50 of 1.3 μM and a Kd of 1.3 μM. In human HepG2 cells, EL244 exhibits low cytotoxicity with an EC50 of 81.2 μM and minimal inhibition of cardiac hERG potassium channels (12% at 25 μM). In vivo, EL244 significantly reduces pulmonary lysophosphatidic acid levels, alleviates fibrosis, restores respiratory function, and has limited systemic absorption. EL244 is suitable for research on idiopathic pulmonary fibrosis.
