Investigations of scope and mechanism of nickel-catalyzed transformations of glycosyl trichloroacetimidates to glycosyl trichloroacetamides and subsequent, atom-economical, one-step conversion to alpha-urea-glycosides

The development and mechanistic investigation of a highly stereoselective methodology for preparing alpha-linked-urea neo-glycoconjugates and pseudo-oligosaccharides is described. This two-step procedure begins with the selective nickel-catalyzed conversion of glycosyl trichloroacetimidates to the corresponding alpha-trichloroacetamides. The alpha-selective nature of the conversion is controlled with a cationic nickel(II) catalyst, [Ni(dppe)(OTf)2] (dppe=1,2-bis(diphenylphosphino)ethane, OTf=triflate). Mechanistic studies have identified the coordination of the nickel catalyst with the equatorial C2-ether functionality of the alpha-glycosyl trichloroacetimidate to be paramount for achieving an alpha-stereoselective transformation. A cross-over experiment has indicated that the reaction does not proceed in an exclusively intramolecular fashion. The second step in this sequence is the direct conversion of alpha-glycosyl trichloroacetamide products into the corresponding alpha-urea glycosides by reacting them with a wide variety of amine nucleophiles in presence of cesium carbonate. Only alpha-urea-product formation is observed, as the reaction proceeds with complete retention of stereochemical integrity at the anomeric C-N bond.

Nanaomycin K, a new epithelial?mesenchymal transition inhibitor produced by the actinomycete ?Streptomyces rosa subsp. notoensis? OS-3966

A new nanaomycin analog, nanaomycin K, was isolated from a cultured broth of actinomycete strain ?Streptomyces rosa subsp. notoensis? OS-3966. Nuclear magnetic resonance (NMR) analyses revealed that the planar structure of nanaomycin K had an ergothioneine moiety. To determine the absolute configuration, nanaomycin K was semisynthesized using standards of nanaomycin E and L-ergothioneine. The natural and semisynthetic nanaomycin K were identified as the same compounds based on retention time, mass spectrometry, 1H NMR, and optical rotation data. Nanaomycin K showed cytotoxicity against Madin?Darby canine kidney (MDCK) cells undergoing transforming growth factor (TGF) beta1-induced epithelial?mesenchymal transition.

MUC1 DECOY PEPTIDES FOR TREATMENT AND PREVENTION OF BACTERIAL INFECTIONS

Pseudomonas aeruginosa flagellin protein recruits the mammalian host sialidase enzyme neuraminidase- 1 (NEU1) to remove sialic acid residues from the extracellular domain of the mammalian cell-surface protein MUC l (MUC l -ED), thereby exposing a cryptic binding site on the MUC l -ED protein backbone for flagellin binding. NEU1 -driven MUC l -ED desialylation rapidly increases P. aeruginosa adhesion to the airway epithelium. MUCl -ED desialylation also increases MUC l -ED cleavage and shedding from the cell surface, where desialylated, shed MUCl -ED competitively blocks P. aeruginosa adhesion to cell-associated MUCl -ED. Presented herein are data showing that exogenously-administered, deglycosylated MUCl -ED peptides reduced adhesion of P. aeruginosa to airway epithelial cells. Also presented are data showing that administration of P. aeruginosa to mice in combination with deglycosylated MUC 1 -ED decreased P. aeruginosa recovered from the lungs at 48 hr and 72 hr post-infection. Such findings are extended to the methods of treatment and prevention of bacterial infections defined herein.

Synthesis, characterization, thermal and DNA-binding properties of new zinc complexes with 2-hydroxyphenones

The neutral mononuclear zinc complexes with 2-hydroxyphenones (ketoH) having the formula [Zn(keto)2(H2O)2] and [Zn(keto)2(enR)], where enR stands for a N,N’-donor heterocyclic ligand such as 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2?-dipyridylamine (dpamH), have been synthesized and characterized by IR, UV and 1H NMR spectroscopies. The 2-hydroxyphenones are chelated to the metal ion through the phenolate and carbonyl oxygen atoms. The crystal structures of [bis(2-hydroxy-4-methoxy-benzophenone)(2,2?-bipyridine) zinc(II)] dimethanol solvate and [bis(2-hydroxy-benzophenone)(2,2?- bipyridine)zinc(II)] dimethanol solvate have been determined by X-ray crystallography. The thermal stability of the zinc complexes has been investigated by simultaneous TG/DTG-DTA technique. The ability of the complexes to bind to calf-thymus DNA (CT DNA) has been studied by UV-absorption and fluorescence emission spectroscopy as well as viscosity measurements. UV studies of the interaction of the complexes with DNA have shown that they can bind to CT DNA and the corresponding binding constants to DNA have been calculated and evaluated. The complexes most probably bind to CT DNA via intercalation as concluded by studying the viscosity of a DNA solution in the presence of the complexes. Competitive studies with ethidium bromide (EB) have shown that the reported complexes can displace the DNA-bound EB, suggesting strong competition with EB for the intercalation site.

Synthesis and antimicrobial activity of 6-sulfo-6-deoxy-D-glucosamine and its derivatives

6-Sulfo-6-deoxy-D-glucosamine (GlcN6S), 6-sulfo-6-deoxy-D-glucosaminitol (ADGS) and their N-acetyl and methyl ester derivatives have been synthesized and tested as inhibitors of enzymes catalyzing reactions of the UDP-GlcNAc pathway in bacteria and yeasts. GlcN6S and ADGS at micromolar concentrations inhibited glucosamine-6-phosphate (GlcN6P) synthase of microbial origin. The former was also inhibitory towards fungal GlcN6P N-acetyl transferase, but at millimolar concentrations. Both compounds and their N-acetyl derivatives exhibited antimicrobial in vitro activity, with MICs in the 0.125?2.0 mg mL?1 range. Antibacterial but not antifungal activity of GlcN6S was potentiated by D-glucosamine and a synergistic antibacterial effect was observed for combination of ADGP and a dipeptide Nva-FMDP.
