Regioselective glycosylation of glucosamine and galactosamine derivates using O-pivaloyl galactosyl donors

Penta-O-pivaloyl-galactopyranose and tetra-O-pivaloyl-galactopyranosyl bromide after electrophilic activation reacted with 6-O-protected 2-azido-galactosides to give the precursor structures of the Thomsen-Friedenreich antigen disaccharide with high regioselectivity, but low yield. With 4,6-O-benzylidene protected 2-azidogalactosides and 2-O-pivaloyl phenylthio galactosides, T-antigen disaccharides of this type were obtained in good yields. Glycosylation reactions of 4,6-O-benzylidene protected glucosamine derivatives with O-pivaloyl protected galactosyl bromide efficiently gave lactolactosamine disaccharides. Even a thioglycoside was efficiently galactosylated by this method resulting in the formation of a disaccharide thioglycoside useful itself as a potential glycosyl donor.

Discovery and Characterization of CD12681, a Potent RORgamma Inverse Agonist, Preclinical Candidate for the Topical Treatment of Psoriasis

With possible implications in multiple autoimmune diseases, the retinoic acid receptor-related orphan receptor RORgamma has become a sought-after target in the pharmaceutical industry. Herein are described the efforts to identify a potent RORgamma inverse agonist compatible with topical application for the treatment of skin diseases. These efforts culminated in the discovery of N-(2,4-dimethylphenyl)-N-isobutyl-2-oxo-1-[(tetrahydro-2H-pyran-4-yl)methyl]-2,3-dihydro-1H-benzo[d]imidazole-5-sulfonamide (CD12681), a potent inverse agonist with in vivo activity in an IL-23-induced mouse skin inflammation model.

Hydroxyphenstatin and the prodrugs thereof

The benzophenone derivative of combretastatin A-1, designated ?hydroxyphenstatin?, was synthesized by compiling a protected bromobenzene and a benzaldehyde to form a benzhydrol which was subsequently oxidized to the ketone. Hydroxyphenstatin was converted to a sodium phosphate prodrug by dibenzyl phosphite phosphorylation and subsequent benzyl cleavage: Hydroxyphenstatin and the prodrugs thereof were found to be a potent inhibitor of tubulin polymerization and to demonstrate surprisingly effective anti neoplastic activity against a series of human cancer cells and murine P388 lymphocytic leukemia cells.

Fungal beta-N-acetylhexosaminidases with high beta-N-acetylgalactosaminidase activity and their use for synthesis of beta-GalNAc-containing oligosaccharides

About 60 fungal strains were tested for production of extracellular beta-N-acetylhexosaminidases. A unique beta-N-acetylhexosaminidase with the beta-GalNAc-ase/beta-GlcNAc-ase ratio of 2.3-2.8 was found in the culture filtrates of some strains of Penicillium oxalicum. Addition of 20% (w/v) MgSO4 increased the beta-GalNAc-ase/beta-GlcNAc-ase ratio to the value of 3.35. Cultivation conditions influence this ratio as well. beta-N-Acetylhexosaminidases from P. oxalicum CCF 2430 and Aspergillus oryzae CCF 1066 considerably differing in the GalNAc-ase activity were used for the synthesis of the following structures beta-D-GalpNAc-(1?4)-D-GlcpNAc, beta-D-GalpNAc-(1?6)-D-GlcpNAc, beta-D-GalpNAc-(1?6)-D-GalpNAc, beta-D-GalpNAc-(1?4)-alpha-D-GlcpNAcOAll and beta-D-GalpNAc-(1?6)-beta-D-Galp-(1?4)-alpha-D-GlcpNAcOAll to demonstrate the application of these new enzymes.

A new class of herbicides that are derivatives of 8-oxabicyclo[3.2.1]oct-6-en-3-one

Treatment of 8-oxabicyclo[3.2.1]oct-6-en-3-one with a catalytic amount of osmium tetraoxide and excess hydrogen peroxide resulted in the formation of the acetonide exo-6,exo-7-isopropylidenedioxy-8-oxabicyclo[3.2.1]oct-3-one (2), in 96% yield. This acetonide was converted into several aromatic alcohols (4a-k) through a Grignard reaction. The alcohols were treated with aqueous HCl in acetone, and the corresponding alkenes (5a-c,e-g,j,k) were obtained in 26-46% overall yield, from the ketone (2). The herbicidal activity of the alkenes was evaluated at a concentra-tion of 6.6 mug g-1. All compounds showed an inhibitory effect (21-66%) on the Sorghum bicolor radicle growth. The inhibition of the accumulation of fresh and dried weight of the aerial parts of Cucumis sativus, after 14 days, varied from 7.1 to 60.7% and from 0.0 to 41.6%, respectively. Compounds (5a,e-g) caused 100% mortality of C. sativus, after 20 days. Compound (5g) (exo-6,exo-7-isopropylidenedioxy-3-(3-methylphenyl)-8-oxabicy-clo[3.2.1]oct-2- ene) was evaluated against several weeds, and it caused 100% mortality of Desmodium tortuosum and Pennisetum setosum.

Inhibition of Mucin-type O-glycosylation through metabolic processing and incorporation of N-thioglycolyl-d-galactosamine peracetate (Ac 5GalNTGc)

Mucin-type O-glycans form one of the most abundant and complex post-translational modifications (PTM) on cell surface proteins that govern adhesion, migration, and trafficking of hematopoietic cells. Development of targeted approaches to probe functions of O-glycans is at an early stage. Among several approaches, small molecules with unique chemical functional groups that could modulate glycan biosynthesis form a critical tool. Herein, we show that metabolism of peracetyl N-acyl-d-galactosamine derivatives carrying an N-thioglycolyl (Ac5GalNTGc, 1) moiety – but not N-glycolyl (Ac 5GalNGc, 2) and N-acetyl (Ac4GalNAc, 3) – through the N-acetyl-d-galactosamine (GalNAc) salvage pathway induced abrogation of MAL-II and PNA epitopes in Jurkat cells. Mass spectrometry of permethylated O-glycans from Jurkat cells confirmed the presence of significant amounts of elaborated O-glycans (sialyl-T and disialyl-T) which were inhibited upon treatment with 1. O-Glycosylation of CD43, a cell surface antigen rich in O-glycans, was drastically reduced by 1 in a thiol-dependent manner. By contrast, only mild effects were observed for CD45 glycoforms. Direct metabolic incorporation of 1 was confirmed by thiol-selective Michael addition reaction of immunoprecipitated CD43-myc/FLAG. Mechanistically, CD43 glycoforms were unperturbed by peracetylated N-(3-acetylthiopropanoyl) (4), N-(4-acetylthiobutanoyl) (5), and N-methylthioacetyl (6) galactosamine derivatives, N-thioglycolyl-d-glucosamine (7, C-4 epimer of 1), and alpha-O-benzyl 2-acetamido-2-deoxy-d- galactopyranoside (8), confirming the critical requirement of both free sulfhydryl and galactosamine moieties for inhibition of mucin-type O-glycans. Similar, yet differential, effects of 1 were observed for CD43 glycoforms in multiple hematopoietic cells. Development of small molecules that could alter glycan patterns in an antigen-selective and cell-type selective manner might provide avenues for understanding biological functions of glycans.

Synthesis, crystal structure, and catalytic properties of a one-dimensional nickel(II) polymer

The title complex [Ni2(C10H9N 3)2(C14H8O5) 2] n, which has an inversion center, midway between two Ni(II) atoms forms a one-dimensional polymer bridged by 4,4?-oxydibenzoate ligands with a NiNi separation of 14.4705(11) A. The Ni(II) atom is six-coordinated by two N atoms of a bis(2-pyridyl)amine ligand and four O atoms from two 4,4?-oxydibenzoate ligands, to form a distorted octahedron coordination geometry and then are linked via N-HO and C-HO hydrogen bonding into a polymeric ribbon structure. The activity and selectivity profiles of the polymer indicate that the optimization temperature and time span are 175C and 30-40 min for the dehydration of cyclohexanol, respectively.

Zinc supplementation of dairy cows: Effects on chemical composition, nutritional quality and volatile profile of Giuncata cheese

The effects of dietary zinc supplementation on chemical composition, nutritional quality and volatile profile of Giuncata cheese were investigated. Dietary zinc addition did not influence milk yield and composition, but induced a marked reduction of somatic cell count. Both in milk and cheese the experimental samples were characterised by a lower concentration of saturated fatty acids and an increase in oleic, vaccenic and rumenic acids. The volatile profile of Giuncata cheese samples was also affected by dietary zinc intake, with an increase in concentration of butanoic acid, hexanoic acid and hexanal. The present results suggest a positive role of zinc in improving animal health and nutraceutical properties of milk and corresponding cheese. Such findings could contribute to the production of cheeses with interesting properties, although further evaluations should be performed to confirm the consumer acceptability of these changes.
