Study of the Mechanism of Electron-Transfer Quenching by Boron−Nitrogen Adducts in Fluorescent Sensors
The mechanism of the change in fluorescence quenching by the amine in boronic acid-based carbohydrate sensor molecules has been explored using density functional theory (DFT). The geometricExpand

The first fluorescent diboronic acid sensor specific for hepatocellular carcinoma cells expressing sialyl Lewis X.
Carbohydrate antigens with subterminal fucosylation have been implicated in the development and progression of several cancers, including hepatocellular carcinoma (HCC). Fluorescent sensors targetingExpand

Regulating the fluorescence intensity of an anthracene boronic acid system: a B-N bond or a hydrolysis mechanism?
An anthracene-based fluorescent boronic acid system developed by the Shinkai group has been widely used for the preparation of fluorescent sensors for carbohydrates. Such application is based on theExpand

A glucose-selective fluorescence sensor based on boronic acid-diol recognition.
A glucose selective diphenylboronic acid fluorescent sensor (10a) with a K(a) of 1472M(-1) has been synthesized and evaluated. This sensor shows a 43- and 49-fold selectivity for glucose overExpand

On the regioselectivity of thioether formation by lacticin 481 synthetase.
Lantibiotic synthetases generate intramolecular thioether cross-links within peptides through the Michael-type addition of cysteines onto dehydroamino acids originating from Ser and Thr. PresentedExpand

The design of boronic acid spectroscopic reporter compounds by taking advantage of the pK(a)-lowering effect of diol binding: nitrophenol-based color reporters for diols.
The complex that forms between a boronic acid and a diol is often much more acidic than the starting boronic acid. In conditions where the solution pH is between the two pK(a) values, the boron atomExpand
