In a Article，once mentioned of 10343-06-3, category: Tetrahydropyrans

A method for the selective activation of thioglycosides that uses the N+-thiophilic reagent Omesitylenesulfonylhydroxylamine (MSH) as a promoter is presented. The reaction proceeds via anomeric mesitylensulfonate intermediates, which could be isolated and fully characterized by placing a fluorine atom at the C2 position. In the presence of a soft Lewis acid, glycosylation reaction proceeds at ambient temperature with good yields. It is further demonstrated that it is possible to orthogonally activate S-ethyl in the presence of S-phenyl donors, enabling the design of sequential glycosylation strategies.

A high-yielding stereoselective method for forming spiroketals from simple ketoallylic diols is reported. Employing catalytic [PdCl2(MeCN) 2] in THF at 0 C, these dehydrative cyclization reactions require only mild conditions to produce vinyl-substituted spiroketals in high yields after brief reaction times with water as the only byproduct. Using this method, the stereochemical information embedded at the nucleophile is transmitted “down-the-chain” and efficiently sets the stereochemistry at both the anomeric carbon atom and the newly formed allylic stereocenter. Down-the-chain: Rapid, high-yielding dehydrative spiroketalization of ketoallylic diols is achieved by efficient catalysis with [PdCl 2(MeCN)2]. The reactions are highly selective for most substrates, with the chiral information of a single stereocenter being communicated, and cyclization occurring, in a “down-the-chain” fashion. Further stereochemical control can be gained by the incorporation of a chiral allylic alcohol (see scheme). Copyright

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, molecular formula is C12H22O11. In a Article，once mentioned of 499-40-1, Formula: C12H22O11

Two platinum(IV) complexes, [Pt(4bt)Cl4] (4) and [Pt(dpyam)Cl4]·DMF (5) (where 4bt is 4,4?-bithiazole and dpyam is 2,2?-dipyridylamine) were prepared from the reaction of H 2PtCl6·6H2O with 4,4?-bithiazole and 2,2?-dipyridylamine, respectively, in methanol. Both complexes were fully characterized and their structures were determined by the X-ray diffraction method. These complexes have a bidentate nitrogenous ligand with four chloride anions attached to a Pt(IV) metal in a distorted octahedral environment. These complexes along with three previously reported analogous complexes were used for in vitro cytotoxicity evaluation against four cultures, NIH-3T3, Caco-2, HT-29 and T47D by MTT assay. The methyl group position in the ligand plays an important role in the cytotoxicity of relevant compounds in different cultures. Interestingly, in some cases, the IC50 values of the new complexes were higher for normal cells but lower against cancer cells in comparison with cisplatin, especially in T47D (breast ductal carcinoma).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C12H22O11, you can also check out more blogs about499-40-1

Glycosaminoglycans (GAGs) are important polysaccharides with various biological functions, but their structures in solution are affected in a complex manner by their component residues. We successfully measured the vacuum-ultraviolet circular dichroism (VUVCD) spectra of six GAGs (chondroitin, chondroitin sulfates, hyaluronic acid, and heparin) and their component sugars (N-acetylaminosugars and uronic acid) from 240 to 160nm by a synchrotron-radiation VUVCD spectrophotometer in aqueous solutions at 25 C. These comprehensive VUVCD spectra revealed the characteristic contribution of the constituent functional groups (sulfate, carboxyl, hydroxyl, hydroxymethyl, acetamido, etc.) and intersaccharide linkages to the higher energy transition of oxygen lone-pair electrons, giving basic information for understanding the detailed structures of GAGs in solution and for their theoretical assignment.

A wide variety of 2-substituted aminoadenosines were prepared for comparison with the moderately A2 receptor selective adenosine agonist 2-anilinoadenosine (CV-1808).High selectivity combined with significant affinity at the A2 receptor in rat membranes was observed for those amines bearing a two-carbon chain to which was attached an aryl, heteroaryl, or alicyclic moiety. 2-(2-Phenethylamino)adenosine (3d), a 14-fold A2 selective compound, was modified by introduction of a variety of substituents in the benzene ring and the side chain.Some of these changes led to improved A2 affinity and increased selectivity.Replacement of the phenyl moiety by cyclohexenyl produced a 210-fold selective agonist 3ag (CGS 22989) whereas the cyclohexanyl analogue 3af (CGS 22492) was 530-fold selective at the A2 site.These compounds showed hypotensive activity in rat models over a range of doses without the bradycardia observed with less selective agonists.

Chitin is one of the most abundant and cheaply available biopolymers in Nature. Chitin has become a valuable starting material for many biotechnological products through manipulation of its N-acetyl functionality, which can be cleaved under mild conditions using the enzyme family of de-N-acetylases. However, the chemoselective enzymatic re-acylation of glucosamine derivatives, which can introduce new stable functionalities into chitin derivatives, is much less explored. Herein we describe an acylase (CmCDA from Cyclobacterium marinum) that catalyzes the N-acylation of glycosamine with a range of carboxylic acids under physiological reaction conditions. This biocatalyst closes an important gap in allowing the conversion of chitin into complex glycosides, such as C5-modified sialosides, through the use of highly selective enzyme cascades.
