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].
Anatoxin-a (ATX-a), a neurotoxic alkaloid, functions as an agonist for the nicotinic acetylcholine receptor (nAChR) and as an inhibitor of Acetylcholinesterase (AChE) [1] [2].
