Novel 1,3,4,6-tetra-O-acyl-N-acyl-d-glucosamine derivatives were synthesized from glucosamine hydrochloride (GlcN·HCl) by the acylation with pyridine as a catalyst. A derivative of tetra-O-acetyl glucosamine contained ketoprofen, a non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic effects, was first synthesized. In analysis of the NMR spectra, the ratio of alpha:beta-anomer showed that penta-acyl-d- glucosamine derivatives and N-acetylated glucosamines containing O-acyl groups have been only the alpha-anomer. Meanwhile, both the intermediates and the glucoconjugate compound of ketoprofen have only the beta-anomer.

Application of 10034-20-5. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride. In a document type is Article, introducing its new discovery.

2-Acetamido-2-deoxy-D-glucose hydrochloride (D-glucosamine hydrochloride) has been used for the preparation of 1,3,4,6-tetra-O-acetyl-2-deoxy-2-trifluoroacetamido-beta- (4) and 2-tetrachlorophthalimido-alpha,beta-D-glucopyranose (6), which have been transformed into the appropriate bromides and the chloride. Both bromo and chloro sugars were used as a glycosyl donors for the glycosylation of diosgenin [(25R)-spirost-5-en-3beta-ol]. These condensations were conducted under mild conditions, using silver triflate as a promoter, and gave diosgenyl glycosides 9 and 12. Each of them was converted into diosgenyl 2-amino-2-deoxy-beta-D-glucopyranoside hydrochloride (11) and N-acylamido derivatives. The structures of all new glycosides were established by 1H and 13C NMR spectroscopy. These diosgenyl glycosides are the first saponins containing the D-glucosamine residue that have been synthesized. These compounds show promising antitumor activities. The synthetic saponins increase the number of apoptotic B cells, in combination with cladribine (2-CdA), that are isolated from chronic lymphotic leukemia (B-CLL) patients.

Synthetic Route of 10034-20-5, An article , which mentions 10034-20-5, molecular formula is C14H22ClNO9. The compound – (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride played an important role in people’s production and life.

Prednisolone succinate-glucosamine (PSG) conjugate, a prodrug for prednisolone, was synthesized and confirmed by NMR and MS spectrum. The stabilities of the prodrug in PBS (pH 2.50, 5.00, 7.20, and 7.89) were studied. Cytotoxicity and uptake assay of the prodrug were perfomed on HK-2 and MDCK cell lines. The results showed that compared with prednisolone, the PSG not only did not increase the cytotoxicity but also improved the uptake to 2.2 times of prednisolone by the cells. Thus, it indicated that glucosamine might be a potential carrier for kidney-targeting delivery of prednisolone.

Synthesis of acylated tri- and tetra-saccharides with one thioureylene group

Monosaccharides joined by urea or thiourea groups, non-ionic isoteric bridges of phosphates, have been studied. These bridges are present in a few natural products such as glycocinnamoylspermidines, a family of broad spectrum antibiotics. Jochims and Seeliger described the first thiourea derivative in which both nitrogen atoms are joined to non-anomeric carbon atoms. In this paper the authors describe the preparation of the ethyl 2-deoxy-2-isothiocyanato-gentiobiosides 1 and 2, the p- methylphenacylthiourea 3, and the thioureylene-trisaccharides (4 anmd 5) and tetrasaccharides (6 abd 7) in which the thourea group joins non-anomeric carbon atoms of mono- or di-saccharides.

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.

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.

This invention relates to a unique process for the preparation of polymeric nanoparticles with target molecules bonded to the surface of the particles and having sizes of up to 1000nm, preferably Inm to 400nm, more preferably Inm to 200nm, that are dispersed homogeneously in aqueous solution. To accomplish the above objective, the polymeric nanoparticles of the subject invention are prepared using a novel technique of microemulsion polymerization. The resulting aqueous solution of polymeric nanoparticles is comprised of about 1 to 100 parts per weight of water or buffer, about 1 to 80 parts per weight of polymeric nanoparticles, which the bio-active molecules are conjugated, about 0.001 to 10 parts per weight of emulsifier, and about 0.00001 to 5 parts per weight of radical initiator based on the weight of the solution. In the method of this invention, the target drug/target substance is covalently bonded to the polymeric nanoparticles to secure them from outer intervention in vivo or cell culture in vitro until they are exposed at the target site within the cell.
