Nitroxyl (HNO), which is the one-electron reduced and further protonated form of nitric oxide, plays important biological functions. A lysosome-targeted dual-photon HNO fluorescent probe (Lyso-HNO), which contains 4-(2-amino-ethyl)morpholine as lysosomal-targetable groups, 1,8-naphthalimide as two-photon fluorophore and triphenylphosphine as HNO reaction site, was synthesized and characterized. The recognition behaviors of Lyso-HNO to HNO were investigated. The results showed that Lyso-HNO exhibited good selectivity and sensitivity to HNO with fast response,. and the detection limit of Lyso-HNO to HNO was estimated to be 202 nmol·L-1. The probe can be applied to bioimaging exogenous lysosomal HNO by two-photon fluorescence confocal microscopy.

Key words: lysosome, dual-photon, nitroxyl, bioimaging
