要旨

Nitroreductase and acidity are common features of a tumor, which is associated with serious disease with a high mortality rate. However, solo detection of nitroreductase or acidic environments may cause false-positive results. Thus, it is very meaningful to develop dual functional probes for detecting nitroreductase and acidity, as these could be used for accurate tumor imaging. Here we report on the first dual functional ratiometric fluorescent probe, NAFP, for acidity and nitroreductase detection. This probe enables the measurement of the acidic microenvironment and the concentration of nitroreductase at the same time and the same site. The probe can obviously distinguish acidity, nitroreductase, and nitroreductase in an acidic environment. Furthermore, confocal fluorescence imaging of A549 cells indicates that NAFP can detect acidity and expressed nitroreductase in living cells.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
