A p-toluenesulfonamide-modified benzo[h]chromene hydrazone: Fluorescent turn-on detection of hypochlorite and its application to imaging the endoplasmic reticula of living cells and zebrafishes

Spectrochim Acta A Mol Biomol Spectrosc. 2023 Aug 5:296:122669. doi: 10.1016/j.saa.2023.122669. Epub 2023 Mar 27.

Abstract

Hypochlorite (ClO-) is a ROS that plays a crucial role in the immune system in the body. As the largest organelle in the cell, the endoplasmic reticulum (ER) manages various life activities. Thus, a simple hydrazone-based probe was designed, which provided a fast turn-on fluorescent response toward ClO-. With a terminal p-toluenesulfonamide group as the endoplasmic reticulum (ER)-specific site, probe 1 was mainly accumulated at ER of living cells, and could be used for imaging endogenous and exogenous HClO in cells and zebrafishes.

Keywords: Aggregation-induced emission; Biological imaging; Endoplasmic reticulum-targeting; Hydrazone; Hypochlorite.
