Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 28244-94-2, Name is 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranoside, molecular formula is C21H26O9S. In a Article，once mentioned of 28244-94-2, SDS of cas: 28244-94-2

The chemoenzymatic synthesis of heparan sulfate tetrasaccharide (1) and hexasaccharide (2) with a fluorous tag attached at the reducing end is reported. The fluorous tert-butyl dicarbonate (FBoc) tag did not interfere with enzymatic recognition for both elongation and specific sulfation, and flash purification was performed by standard fluorous solid-phase extraction (FSPE). Based on an FBoc attached disaccharide as acceptor, a series of partial N-sulfated, 6-O-sulfated heparan sulfate oligosaccharides were successfully synthesized employing fluorous techniques.

Nucleotide sugars are activated sugar precursors used by glycosyltransferases to form glycans. Here we report the first examples of resin-bound nucleotide sugars: fluorinated UDP-galactose and UDP-galactose. They were conjugated to a polyethylene glycol resin through the C6 position with an SMCC linker in good to excellent yields. This synthesis represents an efficient method to access resin-bound nucleotide sugars in a modular approach that enables modifications of the sugar or nucleotide before conjugation. The system has been conceived as a new chemistry-based screening system for enzymes that use UDP-galactose.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view.28244-94-2, Name is 4-Methylphenyl 2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranoside, molecular formula is C21H26O9S. In a Article，once mentioned of 28244-94-2, Computed Properties of C21H26O9S

Inexpensive and readily available sulfonic acids, p-toluenesulfonic acid, and sulfuric acid are versatile and efficient catalysts for the peracetylation of a broad spectrum of carbohydrate substrates in good yield and in a practical time frame. Three appealing features in sulfonic acid-catalyzed acetylation of free sugars were explored including (1) suppression of furanosyl acetate formation for d-galactose and l-fucose; (2) high yielding chemoselective acetylation of sialic acid under appropriate conditions; and (3) peracetylation of amino sugars with different amino protecting functions. Simple one-pot two step acetylation-thioglycosidation methods for the expeditious synthesis of p-tolyl per-O-acetyl thioglycosides were also delineated.

A gram scale synthesis of the glucuronide metabolite of ABT-724 is reported. Glycosidic coupling between a trichloroacetimidate glucuronyl donor and a Cbz-protected hydroxypyridylpiperazine glycosyl acceptor is the key step in the synthesis, since attempts to directly glucuronicrossed d signate the aglycon, aglycon derivatives, and other truncated glycosyl acceptors were unsuccessful. The route was used to produce 2.1 g of metabolite in eight steps from 2-chloro-5-hydroxypyridine in 21% overall yield.

Carbohydrates are involved in many important pathological processes, such as bacterial and viral infections, by means of carbohydrate-protein interactions. Glycoconjugates with multiple carbohydrates are involved in multivalent interactions, thus increasing their binding strengths to proteins. In this work, we report the efficient synthesis of novel muramic and glucuronic acid glycodendrimers as potential Dengue virus antagonists. Aromatic scaffolds functionalized with a terminal ethynyl groups were coupled to muramic and glucuronic acid azides by click chemistry through optimized synthetic strategies to afford the desired glycodendrimers with high yields. Surface Plasmon Resonance studies have demonstrated that the compounds reported bind efficiently to the Dengue virus envelope protein. Molecular modelling studies were carried out to simulate and explain the binding observed. These studies confirm that efficient chemical synthesis of glycodendrimers can be brought about easily offering a versatile strategy to find new active compounds against Dengue virus.
