s Fluorescent Pyrazole Derivatives: An Attractive Scaffold for Biological Imaging Applications

Among the huge number of fluorescent compounds described recently, pyrazole derivatives could play a paramount role in the design of probes for bioimaging applications–an important and simple tool for modern biology because of their easy synthetic methodologies, remarkable optical properties and chelating points. In this mini-review, we highlighted some pyrazole derivatives that have shown remarkable performance in this area; from the detection of chromium (III) with limits of detection of 37 10-12 M to sensing glutathione in biological samples, as well as small molecule labeling of drugs and identifying unhealthy cells such as HeLa and labeling subcellular organelles. Evidently, this important class of N-heterocyclic compounds is part of interesting applications.
