摘　　要：Epilepsy,as a chronic neurological disease of the brain,is closely related to oxidative stress,and the peroxynitrite(ONOO-)significantly rise up in this event.Therefore,ONOO-is considered as a potential biomarker for early prediction of epilepsy.However,some potential diagnostic reagents for epilepsy are hindered by the blood-brain barrier(BBB).Meanwhile,“drug repurposing”is attracting a growing interest.Edaravone(EDA),as a first-line drug in the clinical treatment of cerebral ischemia,plays antioxidant roles in scavenging free radicals,promising potential antiepileptic activity.Thus,it is imperative to develop fluorescent probes for monitoring ONOO-fluctuations in the epileptic brain.Hence,we proposed a novel fluorescent probe with the thiocarbonate as the promising recognition unit for ONOO-and dicyanoisophorone derivative as the fluorophore.Moreover,by the“three-in-one”strategy,the introduction of trifluoromethyl into DCI-ONOO-3 can extend the emission wavelength of the fluorophore,shorten the response and increase lipophilicity.Consequently,DCI-ONOO-3 was used for monitoring ONOO-fluxes in brain of epileptic mice and evaluating the antiepileptic efficacy of EDA.It opens up a new way for the design of BBB permeable fluorescent probes,and provides a convincing new method for the diagnosis and treatment of epilepsy.
