Click chemistry probes have improved the study of drug interactions in live cells and relevant disease models. Proper design of the probes, including the choice of the click moiety coupled to the drug, is crucial to ensure good performance and broad application. A newtrans-cyclooctene derivative, amTCO, was synthesisedviaa novel route using a phthalimide protecting group as a built-in photosensitiser for the cyclooctene isomerization. amTCO improved the physical chemical properties of click chemistry probes compared to standard TCO moieties. An amTCO probe targeting indoleamine 2,3-dioxygenase (IDO1) was a superior tool for visualizing IDO1 and measuring the binding affinities of small molecule inhibitors to IDO1 in cells.
