Dioxetane derivative containing carboxy group as a chemiluminophore‐introducing reagent

Some types of dioxetanes are called chemiluminophores because they produce luminescence light without the use of enzymes. Here, we designed and synthesized a novel carboxy group-containing chemiluminophore derivative, which enabled the simple introduction of such a chemiluminophore to the molecule of interest. Furthermore, we demonstrate that the in vivo imaging system (IVIS imaging system) can recognize tagged chemicals, indicating that such a chemiluminophore could be employed as a tracer molecule for biological studies.
