摘要
Anovelfluorescentprobe9-(4-(1,2-diamine)benzene-N1-phenyl)acridine(DABPA)wassynthesizedforthedetectionofnitricoxide(NO)andcharacterizedbyIR,1H-NMRandEI-MSspectroscopy.Basedonaphotoelectrontransfermechanism,thefluorescenceintensitiesofDABPAwereinvestigatedwiththedifferentconcentrationsofNO.Undertheoptimalexperimentalconditions,thefluorescenceintensityofDABPAhadagoodlinearrelationship(R2=0.9977)withNOconcentrationintherangefrom1×10-7to1.5×10-6mol/Lwithadetectionlimitof1×10-8mol/L.ThecytotoxicityinducedbyDABPAwasevaluatedbytheMTT(3-(4,5-dimethylthiazol-2-yl)-2,5diphenyltetrazoliumbromide)assayforbiologicalapplication.Furthermore,theprobeDABPAhadalsobeensuccessfullyappliedtoreal-timeimageNOproducedinPC12cellsinthepresenceofL-arginine.
