Developing fluorescent probes to image thiols in the living system may provide powerful tools to study the functions of thiol-containing biological molecules. In this study, we report the design and evaluation of a novel turn-on fluorescent probe NQNO for selective detection of thiols in living cells. By introducing an ortho-aldehyde group to NNO, a conventional compound representing a class of thiol-imaging...
Pi class glutathione S-transferase (GSTP1) is highly expressed in various cancerous cells and pre-neoplastic legions, where it is involved in apoptotic resistance or metabolism of several anti-tumour chemotherapeutics. Therefore, GSTP1 is a marker of malignant and pre-malignant cells and is a promising target for visualization and drug development. Here we demonstrate that fluorescein diacetate (FDA),...
