Conjugated polyelectrolytes with aggregation-enhanced emission characteristics: Synthesis and their biological applications

Conjugated polyelectrolytes are promising candidates for the construction of fluorescent bioprobes. In this study, a series of water-soluble fluorescent polyelectrolytes have been designed and synthesized by means of the quaternization of their tetrapheny

ATP (adenosine triphosphate) fluorescent probe based on TPE (tetraphenyl ethylene) as well as preparation method and application of fluorescence probe

The invention relates to a fluorescence probe shown in general formula (I) and a preparation method of the fluorescence probe. The probe takes TPE (tetraphenyl ethylene) as a fluorescence parent, andwhen the probe is completely dissolved in an aqueous solution, the fluorescence signal is weak; when the probe gathers or forms a solid state, the fluorescence signal is significantly enhanced. The probe has good selectivity for ATP (adenosine triphosphate) and can be used as an ATP fluorescence probe. The probe can be used for detecting in-vitro ATP when prepared in an aqueous solution or a buffer solution. The compound can automatically permeate cell membranes to enter cells without any vectors and can be used for intracellular ATP imaging. The fluorescence probe has the advantages of high specifity, light stability, wide response range and the like.

Water-soluble AIE luminogens for monitoring and retardation of fibrillation of amyloid proteins

Compounds that exhibit aggregation induced emission (AIE), and more particularly to water-soluble conjugated polyene compounds that exhibit aggregation induced emission. The conjugated polyene compounds can be used as bioprobes for DNA detection, G-quadru

Design and synthesis of triarylacrylonitrile analogues of tamoxifen with improved binding selectivity to protein kinase C

The clinical selective estrogen receptor modulator tamoxifen is also a modest inhibitor of protein kinase C, a target implicated in several untreatable brain diseases such as amphetamine abuse. This inhibition and tamoxifen's ability to cross the blood br

Photochemical isomerization of norbornadiene-containing polytriazoles obtained by click chemistry polyaddition

Polyesters and polyethers containing norbornadiene (NBD) and 1,2,3-triazole units in the main chain are prepared by step growth polymerization of diester or diether NBD-based dialkynes with different aromatic diazides using copper-catalyzed azide-alkyne c

Investigating the effects of side chain length on the AIE properties of water-soluble TPE derivatives

The emissive properties of fluorophores in aggregated state are important for the development of bio-sensors or bio-imaging reagents. So three water-soluble TPE derivatives with different lengths of side chains have been synthesized and we investigated the effects of side chains on aggregation-induced emission (AIE) properties in the aggregated states. The results indicate that side chains on the fluorophores play a pivotal role in their emission in aggregated state mediated by heparin or solid state, because the coplanarity of these TPE derivatives was affected by side chains. The rates of radiative decay kf and non-radiative decay knr have been obtained through the quantum yields and lifetime, and a larger k f and smaller knr were present for compound TPE-C4N, suggesting that the aggregated TPE-C4N should posses the most remarkable fluorescent property.

The presently described water-soluble conjugated polyene compound are useful as bioprobes for the detection of biomacromolecules, in the manufacture of sensors, in monitoring and retarding formation of amyloid protein fibril in vitro and in vivo, and in developing anti-cancer drugs.

Synthesis and application of photoaffinity probe containing an intact isoprenoid chain

Two novel chemical probes each carrying an intact isoprenoid chain, a biotin tag and a benzophenone moiety were synthesized. Photoaffinity labeling of the Saccharomyces cerevisiae cell lysate revealed that these probes could selectively trap some proteins

Label-free fluorescent probing of G-quadruplex formation and real-time monitoring of DNA folding by a quaternized tetraphenylethene salt with aggregation-induced emission characteristics

Biosensing processes such as molecular beacons require non-trivial effort to covalently label or mark biomolecules. We report here a label-free DNA assay system with a simple dye with aggregation-induced emission (AIE) characteristics as the fluorescent bioprobe. 1,1,2,2-Tetrakis[4-(2-bromoethoxy)phenyl]ethene is nonemissive in solution but becomes highly emissive when aggregated. This AIE effect is caused by restriction of intramolecular rotation, as verified by a large increase in the emission intensity by increasing viscosity and decreasing temperature of the aqueous buffer solution of 1,1,2,2-tetrakis[4-(2- triethylammonioethoxy)phenyl]ethene tetrabromide (TTAPE). When TTAPE is bound to a guanine-rich DNA strand (G1) via electrostatic attraction, its intramolecular rotation is restricted and its emission is turned on. When a competitive cation is added to the G1 solution, TTAPE is detached and its emission is turned off. TTAPE works as a sensitive poststaining agent for Polyacrylamide) gel electrophoresis (PAGE) visualization of G1. The dye is highly affinitive to a secondary structure of G1 called the G-quadruplex. The bathochromic shift involved in the G1 folding process allows spectral discrimination of the G-quadruplex from other DNA structures. The strong affinity of TTAPE dye to the G-quadruplex structure is associated with a geometric fit aided by the electrostatic attraction. The distinct AIE feature of TTAPE enables real-time monitoring of folding process of G1 in the absence of any pre-attached fluorogenic labels on the DNA strand. TTAPE can be used as a K+ ion biosensor because of its specificity to K+-induced and -stabilized quadruplex structure.

Ionic liquid soluble photosensitizers

The preparation and investigation of triplet photosensitizers designed to be preferentially soluble in room-temperature ionic liquids are reported. Photosensitizers prepared by covalent attachment of 1-methylimidazole to aryl ketones are soluble in ionic liquids and remain in the ionic liquid layer when the solution is extracted with an organic solvent. The photosensitized isomerization of trans-β-ionol to cis-β-ionol was efficiently carried out in ionic liquid solution with the product ionol being extracted and the sensitizer/ionic liquid mixture being re-used in additional photosensitization reactions. The scope and utility of the sensitizers in sensitizing other reactions are discussed.
