Rational design of an HClO-specific triggered self-immolative fluorescent turn-on sensor and its bioimaging applications

The development of a rapid and intuitive method for the detection of a specific small molecule biomarker is important for understanding the pathogenesis of relevant diseases. Described here is the design and evaluation of an HClO-specific triggered self-immolative fluorescent sensor (RESClO) based on the structure of an N-protected Resorufin dye. Due to the interrupted π-conjugated structure of the Resorufin dye, the free sensor showed very weak absorption and fluorescence. It can quickly complete the response to HClO (within 10 s) with high selectivity and sensitivity (LOD = 16.8 nM) in aqueous solution. The sensor can be made into test strips to quickly detect HClO in the environment by obvious changes in color and fluorescence. It was successfully used for bioimaging of exogenous and endogenous HClO in cells and zebra fish. More importantly, it can also be used for visual imaging of mouse arthritis models. Thus, sensor RESClO can provide a simple and promising visual analytical tool for the detection of HClO in the environment and the early diagnosis of HClO-mediated related diseases. This journal is

A Mechanism-Based Approach to Screening Metagenomic Libraries for Discovery of Unconventional Glycosidases

Functional metagenomics has opened new opportunities for enzyme discovery. To exploit the full potential of this new tool, the design of selective screens is essential, especially when searching for rare enzymes. To identify novel glycosidases that employ cleavage strategies other than the conventional Koshland mechanisms, a suitable screen was needed. Focusing on the unsaturated glucuronidases (UGLs), it was found that use of simple aryl glycoside substrates did not allow sufficient discrimination against β-glucuronidases, which are widespread in bacteria. While conventional glycosidases cannot generally hydrolyze thioglycosides efficiently, UGLs follow a distinct mechanism that allows them to do so. Thus, fluorogenic thioglycoside substrates featuring thiol-based self-immolative linkers were synthesized and assessed as selective substrates. The generality of the approach was validated with another family of unconventional glycosidases, the GH4 enzymes. Finally, the utility of these substrates was tested by screening a small metagenomic library.

Porphyrin compound and preparation method and application thereof in surface enhanced Raman probe

The invention relates to a porphyrin compound and a preparation method and an application thereof in a surface enhanced Raman probe. The porphyrin compound is 5-[4-(N,N-dimethylamino formyl)phenyl]-15-(4-carboxyl phenyl)porphyrin, and has the structure represented by the formula (I). One end of the prepared porphyrin compound is a carboxyl group which can be firmly adsorbed on the surface of titanium dioxide, and the other end of the prepared porphyrin compound is thiol ester which is adsorbed on a silver surface to form an S-Ag bond. Titanium dioxide nanoparticles and silver nanoparticles form a stable and ordered composite material under connective action of the molecule, and a stable and ordered SERS substrate is formed. The mark molecule is not only a template agent for the substrate but also has a stable signal on the substrate, and has a broad application prospect.

A thiol-thiosulfonate reaction providing a novel strategy for turn-on thiol sensing

The first thiol-specific turn-on probe, BODIPY-TS, utilizing a thiosulfonate scaffold as the thiol recognition unit was reported. BODIPY-TS displays low toxicity, and features high sensitivity, fast response and quantitative reaction towards thiols. The structural novelty of BODIPY-TS would guide the development of novel thiol probes.
