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 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.

Total Synthesis of Dansylated Park’s Nucleotide for High-Throughput MraY Assays

The membrane protein translocase I (MraY) is a key enzyme in bacterial peptidoglycan biosynthesis. It is therefore frequently discussed as a target for the development of novel antibiotics. The screening of compound libraries for the identification of MraY inhibitors is enabled by an established fluorescence-based MraY assay. However, this assay requires a dansylated derivative of the bacterial biosynthetic intermediate Park’s nucleotide as the MraY substrate. Isolation of Park’s nucleotide from bacteria and subsequent dansylation only furnishes limited amounts of this substrate, thus hampering the high-throughput screening for MraY inhibitors. Accordingly, the efficient provision of dansylated Park’s nucleotide is a major bottleneck in the exploration of this promising drug target. In this work, we present the first total synthesis of dansylated Park’s nucleotide, affording an unprecedented amount of the target compound for high-throughput MraY assays.

Synthesis of two oligosaccharides, the GPI anchor glycans from S. cerevesiae and A. fumigatus

Two oligosaccharides, alpha-D-Manp-(1?2)-alpha-D-Manp-(1?2)- alpha-D-Manp-(1?6)-alpha-D-Manp-(1?4)-alpha-D-GlcpNAc (I) and alpha-D-Manp-(1?3)-alpha-D-Manp-(1?2)-alpha-D-Manp-(1?2) -alpha-D-Manp-(1?6)-alpha-D-Manp-(1?4)-alpha-D-GlcpNAc (II), the glycosylphosphatidylinositol (GPI) anchor glycans from S. cerevesiae and A. fumigatus were synthesized as their methyl glycosides in a regio- and stereoselective manner.

An expeditious route to N-Acetyl-D-galactosamine from N-Acetyl-D- glucosamine based on the selective protection of hydroxy groups

GalNAc (1) was straightforwardly prepared from GlcNAc (2a) in six steps. Selective protection of the hydroxy groups on the C-1, C-3, and C-6 positions at the same time was performed by the treatment of TBDPS chloride (5.5 eq.) in DMF in 70% yield. The nucleophilic attack with CsOAc or KOBz on the chloromethylsulfonyloxy group at C-4 worked well (69-77% yield), accompanied by an unexpected rearrangement, to give the furanose products (6). The deprotection of all silyl and acyl groups under acidic conditions and the re-acetylation provided GalNAc (1) in 51% yield.
