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.

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.

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.

Facile synthesis of the fused 6-6-5 ring system containing chroman ring from 2-(1-hydroxy-5-alkenyl)phenol derivatives via intramolecular inverse- electron-demand diels-alder reaction

A simple and facile synthesis of the fused 6-6-5 ring system, i.e., 1,2,3,3a,4,9b-hexahydrocyclopenta[c][1]benzopyrans, was achieved through the intramolecular [4+2] cycloaddition of o-quinonemethides generated from 2-(1- hydroxy-5-alkenyl)phenol derivatives under acidic conditions. In general, cis-fused tricyclic compounds of 6-6-5 ring system were obtained as the major products. Reactivity and selectivity of the cycloaddition reaction depended on the substituents on the aromatic ring and in the dienophilic olefin moiety.

On the effect of the aglycon structure of three aryl beta-D-galactosides on the yield and the regioselecttvity of the transglycolytic synthesis of N-acetyllactosamine

We examined the effect as donors of three aryl beta-D-galactosides (i.e. p-nitrophenyl beta-D-galactopyranoside, o-nitrophenyl beta-D-galactopyranoside and phenyl beta-D-galactopyranoside) on the regioselectivity and the yield of the synthesis of N-acetyllactosamine obtained from the transglycosylation reaction catalyzed by a crude preparation of beta-D-galactosidase from Bacillus circulans at 25C, 37C and 55C, respectively. Using p-nitrophenyl beta-D-galactopyranoside the reaction results were fully regiospecific at all the temperatures considered: the maximum molar yield (74%) was obtained at an incubation temperature of 55C Using o-nitrophenyl beta-D-galactopyranoside as the donor the reaction was still highly regioselective and the maximum molar yield (50%) was achieved at an incubation temperature also of 55C. Using phenyl beta-D-galactopyranoside transglycolytic products appear only at an incubation temperature of 55C but at very low molar yield (about 14%) and lower regioselectivity.
