In heat shock, various enzyme activities are clearly altered due to high body temperature. Evidence accumulated in the last few years indicates that endogenous carboxylesterase (CE) can be regarded as a biomarker of heat shock due to its close relationship to heat shock. To monitor CE activity, this study aims to develop excellent fluorescent probe for CE detection. Fluorescent probe DCM-Br-CE with a NIR turn-on signal at 660 nm and a large Stokes shift of 160 nm, as well as high sensitivity (0.117 x 10-4 U/mL) and good detection capability (30 min) for CE. DCM-Br-CE also has excellent subcell...
