Synthesis, in vitro evaluation and in vivo imaging of a highly selective hydrazine bioluminescent probe based on luciferin-luciferase system

A highly sensitive and selective bioluminescent probe for hydrazine (BPH) was designed, synthe sized and evaluated for detection of hydrazine in vitro and in vivo. BPH was designed to include a specific recogni tion group (acetyl) of hydrazine at an appropriate modification site of the optical reporter hydroxyluciferin (Dluciferin), which showed excellent performance both in selectivity and sensitivity to hydrazine. The results showed that the bioluminescent probe BPH developed in this study is an innovative and widely applicable tool for detecting hydrazine in complex natural environment or in animals.
