Potential HIV protease inhibitors: Preparation of di-N-alkylated 2-, 6-, and 2,6-aminodeoxy-derivatives of D-glucose by direct displacement and by a novel reductive-alkylation procedure

Glucose derivatives carrying branched lipophilic groups at the 2-, 6-, and 2,6-positions were required for biological testing as inhibitors of the protease produced by the human immunodeficiency virus. The synthesis of (N-benzyl-N-ethyl)-2-, 6- and 2,6-diaminodeoxy-D-glucose derivatives is described. The 2-tert-amino group was introduced by a two-step reductive alkylation procedure. The novel tertiary aminosugar, 2,6-di-(N-benzyl-N-ethyl)amino-2,6-dideoxy-D-glucose, was made via direct substitution of the sulphonate group in allyl 2-acetamido-2-deoxy-6-O-tosyl-D-glucopyranoside with N-benzylethylamine.

Metabolomic analysis of blood plasma after oral administration of N-acetyl-D-glucosamine in dogs

N-acetyl-D-glucosamine (GlcNAc) is a monosaccharide that polymerizes linearly through (1,4)-beta-linkages. GlcNAc is the monomeric unit of the polymer chitin. GlcNAc is a basic component of hyaluronic acid and keratin sulfate found on the cell surface. The aim of this study was to examine amino acid metabolism after oral GlcNAc administration in dogs. Results showed that plasma levels of ectoine were significantly higher after oral administration of GlcNAc than prior to administration (p < 0.001). To our knowledge, there have been no reports of increased ectoine concentrations in the plasma. The mechanism by which GlcNAc administration leads to increased ectoine plasma concentration remains unclear; future studies are required to clarify this mechanism. 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.HPLC of Formula: C8H15NO6, you can also check out more blogs about14215-68-0

Novel amide-functionalized chloramphenicol base bifunctional organocatalysts for enantioselective alcoholysis of meso-cyclic anhydrides

A family of novel chloramphenicol base-amide organocatalysts possessing a NH functionality at C-1 position as monodentate hydrogen bond donor were developed and evaluated for enantioselective organocatalytic alcoholysis of meso-cyclic anhydrides. These structural diversified organocatalysts were found to induce high enantioselectivity in alcoholysis of anhydrides and was successfully applied to the asymmetric synthesis of (S)-GABOB.

Highly enantioselective thiolysis of prochiral cyclic anhydrides catalyzed by amino alcohol bifunctional organocatalysts and its application to the synthesis of pregabalin

Asymmetric thiolysis of prochiral cyclic anhydrides was achieved with our developed chiral sulfonamide and squaramide bifunctional organocatalysts based on amino alcohol scaffolds.

The synthesis and evaluation of new benzophenone derivatives as tubulin polymerization inhibitors

Inspired by the potent inhibition activity of phenstatin and millepachine against cancer cell growth, a series of new benzophenone derivatives were synthesized and evaluated as tubulin polymerization inhibitors. Among them, compound 10a exhibited 0.029-0.062 muM of IC50 for five human cancer cell lines, which is much better than that of the two leading compounds. Flow cytometric analysis showed that 10a induces G2/M phase arrest and apoptosis in A549 cells. Cellular studies revealed that the induction of apoptosis by 10a was associated with the collapse of the mitochondrial membrane potential (MMP). Overall, the current study demonstrates that the benzophenone derivatives are promising anticancer agents by targeting tubulin.

Synthesis of N-(fluoren-9-ylmethoxycarbonyl)glycopyranosylamine uronic acids

The synthesis of 10 N-(fluoren-9-ylmethoxycarbonyl)glycopyranosylamine uronic acids that are amenable to solid-phase synthesis is described. The general synthetic strategy involves initial incorporation of the protected amine, followed by selective TEMPO oxidation of C-6 hydroxyl groups to give the corresponding Fmoc-protected sugar amino acids. Amine incorporation may be accomplished from aminolysis of the free sugar or from glycosyl azide reduction. The reactions can be carried out on multigram scale, providing access to unique monomer units for future incorporation into combinatorial library syntheses.

N-acetylglucosamine, the building block of chitin, inhibits growth of Neurospora crassa

N-acetylglucosamine (GlcNAc) is the monomer of the polysaccharide chitin, an essential structural component of the fungal cell wall and the arthropod exoskeleton. We recently showed that the genes encoding the enzymes for GlcNAc catabolism are clustered in several ascomycetes. In the present study we tested these fungi for growth on GlcNAc and chitin. All fungi, containing the GlcNAc gene cluster, could grow on GlcNAc with the exception of four independent Neurospora crassa wild-type isolates, which were however able to grow on chitin. GlcNAc even inhibited their growth in the presence of other carbon sources. Genes involved in GlcNAc catabolism were strongly upregulated in the presence of GlcNAc, but during growth on chitin their expression was not increased. Deletion of hxk-3 (encoding the first catabolic enzyme, GlcNAc-hexokinase) and ngt-1 (encoding the GlcNAc transporter) improved growth of N. crassa on GlcNAc in the presence of glycerol. A crucial step in GlcNAc catabolism is enzymatic conversion from glucosamine-6-phosphate to fructose-6-phosphate, catalyzed by the glucosamine-6-phosphate deaminase, DAM-1. To assess, if DAM-1 is compromised in N. crassa, the orthologue from Trichoderma reesei, Trdam1, was expressed in N. crassa. Trdam1 expression partially alleviated the negative effects of GlcNAc in the presence of a second carbon source, but did not fully restore growth on GlcNAc. Our results indicate that the GlcNAc-catabolism pathway is bypassed during growth of N. crassa on chitin by use of an alternative pathway, emphasizing the different strategies that have evolved in the fungal kingdom for chitin utilization.
