Electric Literature of 17261-28-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.17261-28-8, Name is 2-(Diphenylphosphino)benzoic acid, molecular formula is C19H15O2P. In a patent, introducing its new discovery.
Dual-Site Fluorescent Probe to Monitor Intracellular Nitroxyl and GSH-GSSG Oscillations
Nitroxyl (HNO), the one-electron-reduction product of NO has recently been revealed to have potentially beneficial pharmacological properties in cardiovascular health as a result of interactions with specific thiols such as glutathione (GSH). To disentangle the complicated inter-relationship between HNO and GSH in the signal transduction and oxidative pathways, we designed and synthesized a dual-site fluorescent probe NCF to indicate cellular HNO and GSH-GSSG balance. The sensitive and selective detection of HNO was achieved by incorporating an organophosphine group to naphthaldehyde-TCF. Then the resulted fluorescent product is able to monitor the conversion of GSH and GSSG reversibly. Additionally, outstanding biocompatibility make it capable of monitoring intracellular HNO and consequently GSH-GSSG oscillationsin living cells. We anticipate that NCF will be a unique molecular tool to investigate the interplaying roles of HNO and GSH.
