BI-2545 is an autotaxin (ATX) inhibitor that significantly reduces LPA. For human ATX and rat ATX, the IC50s values are 2.2 nM and 3.4 nM , respectively.
PAT-347 is a potent inhibitor of Autotaxin (ATX), a secreted enzyme responsible for the hydrolysis of lysophosphatidylcholine (LPC) to the bioactive lysophosphatidic acid (LPA) and choline.
ATX inhibitor 15 (compound 30) is an indole-based carbamate derivative with a strong inhibitory effect on autotaxin (ATX), demonstrated by an IC50 of 2.17 nM. Additionally, ATX inhibitor 15 effectively inhibits ATX activity in vivo and suppresses the expression of pro-fibrotic genes. Furthermore, ATX inhibitor 15 exhibits protective effects in lung fibrosis induced by Bleomycin in mice [1].
