Abstract
A turn-on fluorescence probe PQP-1 with a pyrroloquinoline skeleton has been designed and synthesized. Probe PQP-1 showed high sensitivity to HSO3-, low detection limit (16.83 nM), and a wide linear range (50-3000 μM). More importantly, probe PQP-1 could distinguish between HSO3- and SO32-. Furthermore, cell imaging experiments of HSO3- in HeLa cells revealed that probe PQP-1 had potential application value in biological systems.

[PMID: 35447358 DOI: 10.1016/j.ymeth.2022.04.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/11/2022] [Accepted: 04/14/2022] [Indexed: 12/12/2022] Open
Abstract
Bisulfite (HSO3-) has been widely used as an important food additive in daily life. Furthermore, a normal amount of HSO3- plays a significant role in biological systems. However, excessive intake of HSO3- will lead to a variety of diseases. Therefore, it is of great significance to develop an efficient fluorescent probe that can be used for detection of HSO3- in biological systems and food samples. In this work, a near-infrared (NIR) emitted fluorescent probe (SZY) based on hemicyanine dye was successfully synthesized and applied to detect HSO3- in several food samples and live animals. The proposed nucleophilic addition sensing mechanism of SZY towards HSO3- has been confirmed by 1H NMR titration, high resolution mass spectrometry (HR-MS) and density functional theory (DFT) theoretical computation. The HSO3--induced nucleophilic reaction with α,β-unsaturated C=C binding of SZY results in the dramatic decline of the UV-vis absorption and remarkable quenching of the fluorescence emission. SZY features the advantages of near infrared emission (centered at 720 nm), high water solubility (in 98% aqueous solution), fast response time (50 s), large Stokes shift (244 nm) and low cytotoxicity. The probe SZY was successfully applied to image of HSO3- in live nude mouse and adult zebrafish. Semi-quantitatively analyzing the HSO3- level by "naked eye" in several food samples including canned fruit, white wine, white sugar and jasmine tea drinks has been realized by the colorimetric method.
