Efficient preparation of three building blocks for the synthesis of heparan sulfate fragments: Towards the combinatorial synthesis of oligosaccharides from hypervariable regions

New, multigram routes to suitably protected L-iduronyl monosaccharide donors 4 and 5 and 2-azidoglucose acceptors 6 and 7 are described. The L-iduronyl and D-glucuronyl disaccharides 1-3 were then prepared from these compounds, by means of efficient and regioselective protective group manipulations. These disaccharides form the basis of a combinatorial approach toward the synthesis of heparan sulfate fragments representative of the heterogeneous regions of this polysaccharide.

A divergent synthesis of 2-acyl derivatives of PUGNAc yields selective inhibitors of O-GlcNAcase

A divergent route facilitating the rapid synthesis of a series of O-(2-acetamido-2-deoxy-d-glucopyranosylidene)amino N-phenylcarbamate (PUGNAc)-based inhibitors, bearing different N-acyl groups has been developed. All compounds of this series are inhibitors of both human O-GlcNAcase and human beta-hexosaminidase, yet some effectively exploit differences between the active site architectures of these two human enzymes which render them selective for O-GlcNAcase. Such inhibitors may be valuable tools in dissecting the role of the O-GlcNAc post-translational modification at the cellular and organismal level since these compounds may have different pharmacokinetic properties when compared to other inhibitors of beta-N-acetyl-glucosaminidases.

COMBINATION PHARMACEUTICAL COMPOSITIONS AND USES THEREOF

The present invention provides for methods and pharmaceutical compositions for treating proliferative disorders. In one aspect, the method comprises administration of two cell-cycle suppressors having a synergistic effect. In another aspect, two cell-cycle suppressors having a synergistic effect are provided in a pharmaceutical composition.

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: C5H10O2, you can also check out more blogs about2081-44-9

Metal chelation by the common 2-amino-2-deoxy-, 2-N-acetylamino-2-deoxy-, and 2-deoxy-hexoses

The chelating properties of the common aldohexoses d-glucose, d-mannose, and d-galactose are characteristically modified in 2-substituted derivatives. The 2-amino-2-deoxy-aldohexoses provide mono- and bis-metallisable anionic ligands after their reaction with metal probes of the PdIIN 2 type (N2 = bidentate nitrogen ligand). The 2-amino function reliably participates in metal binding of the, mostly pyranoidic, carbohydrate chelators. Acetylation of the amino function yields the biologically important 2-N-acetylamino-2-deoxy-hexoses (GlcNAc, ManNAc, and GalNAc). On reaction with the palladium probe, the metal-binding properties of the deprotonated acetylamino function depends on the steric requirements introduced by the acetyl residue which is forced into a coplanar arrangement with the chelate ring. In the two 2-deoxy-aldohexoses, 2-deoxy-arabino-d-hexose (the 2-deoxy derivative of both d-glucose and d-mannose, ‘2-deoxy-glucose’) and 2-deoxy-lyxo-d-hexose (‘2-deoxy galactose’), the 2-position cannot contribute to metal binding. As a result, furanose-1,3 chelation becomes an important metal-binding mode. Due to the decreased acidity of the 2-deoxy-glycose’s 1-hydroxy function, monometallation also takes place at the pyranose’s 3,4-site.

Effective protection of the N-sulfate of glucosamine derivatives with the 2,2,2-trichloroethyl group

The 2,2,2-trichloroethyl (TCE) group was utilized as the first protecting group for N-sulfates (chlorosulfuric acid TCE ester, Et3N, DMAP, DMF). Glycosylation with 3,4,6-tri-O-acetyl-N-trichloroethylsulfuryl-alpha-d-glucosaminosyl trichloroacetimidate provided the corresponding beta-glucosaminosides stereoselectively and in excellent yields. The TCE protection stayed stable under a variety of conditions for the manipulation of other protecting groups, and was readily removable with zinc in the presence of ammonium chloride in methanol.
