(A) Structure and response of probe 27. (B) Fluorescence spectra of probe 27 upon addition of NO (200 μM) and GSH (200 μM) for 1 h. (C) Fluorescence imaging of probe 27 (2 μM, 5 min) in HUVECs: (a1–a3) pretreated with NEM (1 mM, 30 min), (b1–b3) pretreated with DEA·NONOate (200 μM, 15 min), (c1–c3) non-pretreated, and (d1–d3) pretreated with NEM (1 mM, 30 min) and then DEA·NONOate (200 μM,15 min).
