Abstract

Autotaxin (ATX) is a secreted enzyme with tissue levels associated with tissue injury, which increase during wound healing and chronic fibrotic diseases. We selected [18F]-(R,E)-3-(4-chloro-2-((5-methyl-2H-tetrazol-2-yl)methyl) phenyl)-1-(4-((5-(2-fluoroethoxy)pyridin-2-yl)methyl)-2-methylpiperazin-1-yl)prop-2-en-1-one ([18F]PRIMATX, [18F]2), a tracer for positron emission tomography, to image ATX expression in vivo. It successfully differentiates expression levels in lung tissue samples from idiopathic pulmonary fibrosis patients, and allows the detection of ATX-expressing tumours in living mice, confirming its potential for development as a clinical imaging agent.
