  Water-soluble 4-hydroxystyryl and 4-hydroxyphenyl-butadienyls dyes with switchable fluorescence

  摘要：

  Fluorescent 4-hydroxystyryl dyes are useful for many biomedical and pharmaceutical assays, and other analyte sensing applications. However, these dyes often suffer from limited applicability in analytical and bioanalytical utilization due to insufficient water-solubility, high acid-Ionization constants (pK(a)) and short-wavelength absorption and emission. To solve these issues, a series of new, water-soluble 4-hydroxystyryl and longer-wavelength 4-hydroxyphenyl-butadienyl dyes were synthesized and the spectral and protolytic properties were studied. These new dyes contain electron-withdrawing substituents ortho to the triggering 4-hydroxyl group. The introduction of the cyano and formyl groups was found to decrease the pK(a) and extend the pH-sensing region of these fluorophores. In respect of the molecular structure, these dyes exhibit either a "turn-on" activatable fluorescence, or a dual-fluorescence that enables ratiometric measurements. The 4-hydroxyphenyl-butadienyl dye was evaluated for fluorescence monitoring of drug delivery. These new dyes are promising fluorophores for acidity measurements and other sensing applications.

• Water solubility is essential for fluorescent probes to image hypochlorous acid in live cells

  We synthesised four probes and compared their HClO-detecting ability in different solvents. The data showed that only hydrophilic probes could sensitively and accurately detect HClO in live cells. Meanwhile, the addition of organic solvents, as is commonly practised, weakens the oxidising capacity of HClO and thus generates inaccurate outcomes.

  我们合成了四种探针，并比较了它们在不同溶剂中对HClO的检测能力。数据表明，只有亲水性探针才能灵敏，准确地检测活细胞中的HClO。同时，通常采用的添加有机溶剂会削弱HClO的氧化能力，从而产生不准确的结果。

  The development of highly sensitive fluorescent probes in combination with innovative optical techniques is a promising strategy for intravital noninvasive quantitative imaging. Cyanine fluorochromes belong to a superfamily of dyes that have attracted substantial attention in probe design for molecular imaging. We have developed a novel paradigm to introduce a Turn-ON mechanism in cyanine molecules, based on a distinctive change in their pi-electrons system. Our new cyanine fluorochrome is synthesized through a simple two-step procedure and has an unprecedented high fluorescence quantum yield of 16% and large extinction coefficient of 52 000 M(-1) cm(-1). The synthetic strategy allows one to prepare probes for various analytes by introducing a specific triggering group on the probe molecule. The probe was equipped with a corresponding trigger and demonstrated efficient imaging of endogenous hydrogen peroxide, produced in an acute lipopolysaccharide-induced inflammation model in mice. This approach provides, for the first time, an available methodology to prepare modular molecular Turn-ON probes that can release an active cyanine fluorophore upon reaction with specific analyte.
