Solvent-free mechanochemical synthesis of aryl glycosides

Aryl glycosides have been prepared from a range of readily available glycosyl halides by a solvent-free mechanochemical procedure employing a planetary ball mill in excellent yields. Besides being a solvent-free reaction, the procedure has been successful in eliminating the need for employing any phase-transfer catalyst in the reaction. Copyright Taylor & Francis Group, LLC.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.10343-06-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10343-06-3, in my other articles.

Large-scale production of N-acetyllactosamine through bacterial coupling

A large-scale production system of N-acetyllactosamine, a core structure of various oligosaccharides, was established by a whole-cell reaction through the combination of recombinant Escherichia coli strains and Corynebacterium ammoniagenes. Two recombinant E. coli strains over-expressed the UDP-Gal biosynthetic genes and the beta-(1?4)-galactosyltransferase gene of Neisseria gonorrhoeae, respectively. C. ammoniagenes contributed the production of UTP from orotic acid. N-Acetyllactosamine was accumulated at 279 mM (107 g L-1) after a 38 h reaction (2.5 L in volume) starting from orotic acid, d-galactose, and 2-acetamido-2-deoxy-d-glucose.

Discovery of Potent and Selective Inhibitors for G9a-Like Protein (GLP) Lysine Methyltransferase

G9a-like protein (GLP) and G9a are highly homologous protein lysine methyltransferases (PKMTs) sharing approximately 80% sequence identity in their catalytic domains. GLP and G9a form a heterodimer complex and catalyze mono- and dimethylation of histone H3 lysine 9 and nonhistone substrates. Although they are closely related, GLP and G9a possess distinct physiological and pathophysiological functions. Thus, GLP or G9a selective small-molecule inhibitors are useful tools to dissect their distinct biological functions. We previously reported potent and selective G9a/GLP dual inhibitors including UNC0638 and UNC0642. Here we report the discovery of potent and selective GLP inhibitors including 4 (MS0124) and 18 (MS012), which are >30-fold and 140-fold selective for GLP over G9a and other methyltransferases, respectively. The cocrystal structures of GLP and G9a in the complex with either 4 or 18 displayed virtually identical binding modes and interactions, highlighting the challenges in structure-based design of selective inhibitors for either enzyme.

Probing the limitations of the fluorous content for tag-mediated microarray formation

The synthesis of a di-perfluorohexyl tag is reported for use in a fluorous-based carbohydrate microarray. A comparative microarray study with this di-perfluorohexyl tag and a mono-perfluorooctyl and mono-perfluorohexyl tag found the increased fluorous content conducive to better spot morphology and easier washing protocols without precluding reuse of the fluorous slide.
