dc.description.abstractThe abnormal location or generation of superoxide radical anion (O2 •-) are implicated in many diseases, including cancers; thus, development of an efficient method to detect O2 •- is of great importance. Inspired by the fluorophore-governed selective manner to O2 •- and peroxynitrite (ONOO-) of previously reported phosphinate-based fluorescence probes, in this contribution, a phosphinothioate-containing probe, TPP, was designed. The probe exhibited easy accessibility through a one-step sequence and good photostability and biocompatibility. Interestingly, TPP showed high specificity and sensitivity to O2 •- over other reactive oxygen species/nitrogen species including ONOO-. Furthermore, with the assistance of two-photon microscopy, TPP was successfully applied for imaging endogenous O2 •- in live cells and tissues.-
dc.description.sponsorshipThis study was supported financially by a National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP) (No. 2012R1A3A2048814 for J. Yoon and No. 2019R1A2B5B03100278 for H. M. Kim). The Korea Basic Science Institute (Western Seoul) is acknowledged for the LC/MS data. FAB mass spectral data were obtained from the Korea Basic Science Institute (Daegu) on a Jeol JMS 700 high-resolution mass spectrometer.-
