Design strategy of multifunctional and high efficient hydrogen sulfide NIR fluorescent probe and its application in vivo

With the improvement of organic synthesis technology and the development of fluorescent probe, more and more fluorescent probes with excellent performance and versatility are required, so as to better realize their application value. High sensitivity, high selectivity, targetable and fast response NIR fluorescence probes are still needed for hydrogen sulfide precise detection. In this study, phenol containing 2, 4-dinitro group was selected as a strong electrophilic group to promote the nucleophilic substitution reaction. After the nucleophilic addition reaction between probe and hydrogen sulfide with delicate structure, strong nucleophile, 2, 4-dinitrophenol departure quickly and the NIR fluorophore was released, which showed fluorescence emission at 741 nm, and the probe detection limit for hydrogen sulfide was calculated as 96 nM. Interestingly, because of the positive charge in the hemiocyanine, the probe can locate efficiently in the mitochondria. This fluorescent probe with excellent performance was used to detect the endogenous levels of hydrogen sulfide in vivo. This work provides guidance for the design of multifunctional and high-performance fluorescent probes.

Thiol-Chromene "Click" Reaction Triggered Self-Immolative for NIR Visualization of Thiol Flux in Physiology and Pathology of Living Cells and Mice

Understanding the pathological process of biological systems can greatly improve the prevention and treatment of diseases. The study of pathological processes has now reached the molecular level, and molecular fluorescent probes have become a powerful tool. Chromene, also known as benzo-pyran molecule, is a structural element of natural products with good biological compatibility and was developed as a fluorescent probe. The thiol-chromene "click" nucleophilic pyran ring-opening reaction allows the quick detection of thiol. In this work, the chromene alcohol can function as an efficient self-immolative spacer, which covalently links NIR fluorophore via a carbonyl ester. Due to its favorable characteristics and superior applicability, the self-immolative amplifier NIR-HMPC achieves the specific, rapid, sensitive, NIR fluorescent detection of thiols. Furthermore, the indoles iodized salt in the system can specifically target thiols in mitochondria. Thus, this probe was used to visualize the fluctuations of thiols during oxidative stress and cell apoptosis, cerebral ischemia reperfusion, demonstrating that it is valuable for elucidating pathophysiology process in living organism. This discovery provides an effective means for studying the pathological process of thiol related diseases.

Photophysical properties of near-IR cyanine dyes and their application as photosensitizers in dye sensitized solar cells

The photophysical properties of eight structurally diverse near-infrared cyanine dyes were investigated with respect to their structural features and potential use as light-harvesting sensitizers of dye sensitized solar cells. The absorption, emission, and lifetime characteristics of the dyes were assessed under a variety of conditions. The photophysical properties and sensitizing efficiency of three of the eight dyes, with an additional six-membered cyclic ring, were markedly different from the other five. The dyes absorbed light of wavelength within the range of 779–823 nm and emitted within the range of 832–876 nm.The dyes had fluorescence quantum yield in the range of 14–22%. The surface morphology and elemental analysis of the cyanine dye sensitized photoanodes were characterized via Field-Emission Scanning Microscopy Imaging (FESEM) and Transmission Electron Microscopy (TEM). The performance of the fabricated cyanine dye sensitized solar cells was assessed via current-voltage and electrochemical impedance spectroscopic measurements. The solar-to-electric power conversion efficiency ranged from 0.04% to 0.24%.

A New Method for the Synthesis of Heptamethine Cyanine Dyes: Synthesis of New Near-Infrared Fluorescent Labels

A new uncatalyzed synthesis of heptamethine cyanine dyes is described.The reaction involves heating a mixture of N-alkyl-substituted quaternary salts derived from 2,3,3-trimethylindole or 2,3,3-trimethylbenzindole and 2-chloro-1-formyl-3-(hydroxymethylene)cyclohex-1-ene to reflux in a mixture of 1-butanol and benzene (7:3) as solvent.No catalyst is used, and water is removed as an azeotrope.The resulting chloro compounds possess strong absorption and fluorescence properties in the near-infrared region and are converted to dyes bearing reactive functionalities such as hydroxy and isothiocyanate groups useful as fluorescent tags for nucleic acids and proteins.Several symmetric and nonsymmetric dyes have been synthesized in high yields.
