摘要：

A novel chemiluminescent probe for detection of cysteine (Cys) from other biothiols has been reported by utilizing the excellent chemiluminescent Schaap's adamantylidene-dioxetane scaffold. After careful assessment, the probe CL-Cys could detect Cys with high sensitivity and total light photons increased by 28-fold after the probe was treated with Cys, with the detection limit of 7.5 X 10(-8) M. Finally, CL-Cys was further utilized for the chemiluminescent imaging of endogenous Cys in a living mouse. In general, this probe has a remarkable ability to detect Cys, which provides a valuable method for interrogation of the Cys roles in more biological and pathological processes.
