Stereoselective synthesis of a C-linked neuraminic acid disaccharide: potential building block for the synthesis of C-analogues of polysialic acids.

ABSTRACT: C-linked neuraminic acid disaccharide was synthesized in a diastereoselective manner from a sulfone donor and aldehyde acceptor, which was protected as a propargyl ether, through a samarium-mediated coupling reaction. The resulting disaccharide has acetal and phenyl sulfide functional groups that can be easily converted into aldehyde and phenyl sulfone groups by photolysis and oxidation reactions to serve as disaccharide acceptor and donor, respectively.

Synthesis of nor-C-linked neuraminic acid disaccharide: a versatile precursor of C-analogs of oligosialic acids and gangliosides.

Project description:The Neu5Acalpha(2,8)Neu5Ac disaccharide is an important constituent of tumor related antigen, however, the O-linkage is catabolically unstable. Vaccination with a catabolically stable sialic acid C-glycoside analog might enhance immunogenicity. The synthesis of Neu5Ac nor-C-disaccharide 20R/S, corresponding to versatile precursors of C-analogs of oligosialic acid and gangliosides, is reported. The synthesis of the protected acceptor was not straightforward, as ester, silyl ether, and isopropylidene protection failed to afford desired C-linked disaccharide. Allyl ether protection of hydroxyl groups and acetyl protection of the acetamido facilitated the successful synthesis of the 8-aldehyde neuraminyl acceptor. Samarium mediated C-glycosylation afforded the desired nor-C-disaccharide as a mixture of two separable diastereomers.

Total synthesis of TMG-chitotriomycin based on an automated electrochemical assembly of a disaccharide building block.

Project description:The total synthesis of TMG-chitotriomycin using an automated electrochemical synthesizer for the assembly of carbohydrate building blocks is demonstrated. We have successfully prepared a precursor of TMG-chitotriomycin, which is a structurally-pure tetrasaccharide with typical protecting groups, through the methodology of automated electrochemical solution-phase synthesis developed by us. The synthesis of structurally well-defined TMG-chitotriomycin has been accomplished in 10-steps from a disaccharide building block.

Solution phase conformation and proteolytic stability of amide-linked neuraminic acid analogues.

Project description:Amide-linked homopolymers of sialic acid offer the advantages of stable secondary structure and increased bioavailability making them useful constructs for pharmaceutical design and drug delivery. Defining the structural characteristics that give rise to secondary structure in aqueous solution is challenging in homopolymeric material due to spectral overlap in NMR spectra. Having previously developed computational tools for heteroologomers with resolved spectra, we now report that application of these methods in combination with circular dichroism, NH/ND NMR exchange rates and nOe data has enabled the structural determination of a neutral, δ-amide-linked homopolymer of a sialic acid analogue called Neu2en. The results show that the inherent planarity of the pyranose ring in Neu2en brought about by the α,δ-conjugated amide bond serves as the primary driving force of the overall conformation of the homooligomer. This peptide surrogate has an excellent bioavailability profile, with half-life of ∼12 h in human blood serum, which offers a viable peptide scaffold that is resistant to proteolytic degradation. Furthermore, a proof-of-principle study illustrates that Neu2en oligomers are functionalizable with small molecule ligands using 1,3-dipolar cycloaddition chemistry.

Diversity-oriented synthesis of peptide-boronic acids by a versatile building-block approach.

Project description:A new strategy for the synthesis of peptide-boronic acids (PBAs) is presented. 20 Fmoc-protected natural amino acids with orthogonal side-chain protection were straightforwardly converted into their corresponding boron analogues in three simple steps. Subsequent immobilisation on commercially available 1-glycerol polystyrene resin and on-resin transformations yielded a diversity of sequences in high purity. The strategy eliminates various synthetic obstacles such as multi-step routes, low yields, and inseparable impurities. The described method comprises great potential to be implemented in automated combinatorial approaches by markedly facilitating the access to a variety of PBAs. The coupling of amino acids or other building blocks with α-aminoboronates allows the creation of hybrid molecules with significant potential in various scientific disciplines, such as medicinal chemistry, structural biology, and materials science.

First and stereoselective synthesis of an ?-(2?5)-linked disaccharide of 3-deoxy-D-manno-oct-2-ulosonic acid (Kdo).

Project description:Resistance of bacterial pathogens toward antibiotics has revived interest in lipopolysaccharide (LPS) motifs as potential therapeutic targets. The LPS of several pathogenic Acinetobacter strains comprises a 4,5-branched Kdo trisaccharide containing an uncommon (2?5)-linkage. In this contribution the first stereoselective glycosylation method for obtaining an ?-Kdo-(2?5)-?-Kdo disaccharide in good yield is highlighted. The synthetic approach used for accessing this linkage type will allow for future studies of the immunoreactivity associated with this unique bacterial Kdo inner core structure.

Synthesis of a C-linked hyaluronic acid disaccharide mimetic.

Project description:The synthesis of a C-disaccharide that is designed as a mimetic for the repeating unit disaccharide of hyaluronic acid is described. The target compound was obtained via the SmI2-promoted coupling reaction of the sulfone, 2-acetamido-4,6-O-benzylidene-3-O-tert-butyldimethylsilyl-1,2-dideoxy-1-pyridinylsulfonyl-beta-D-glucopyranose (6), and the aldehyde, p-methoxyphenyl 2,3-di-O-benzyl-4-deoxy-4-C-formyl-6-O-p-methoxybenzyl-beta-D-glucopyranoside (14).

Synthesis of LewisX-O-Core-1 threonine: A building block for O-linked LewisX glycopeptides.

Project description:LewisX (LeX) is a branched trisaccharide Gal?1?4(Fuc?1?3)GlcNAc that is expressed on many cell surface glycoproteins and plays critical roles in innate and adaptive immune responses. However, efficient synthesis of glycopeptides bearing LeX remains a major limitation for structure-function studies of the LeX determinant. Here we report a total synthesis of a LeX pentasaccharide 1 using a regioselective 1-benzenesulfinyl piperidine/triflic anhydride promoted [3 + 2] glycosylation. The presence of an Fmoc-threonine amino acid facilitates incorporation of the pentasaccharide in solid phase peptide synthesis, providing a route to diverse O-linked LeX glycopeptides. The described approach is broadly applicable to the synthesis of a variety of complex glycopeptides containing O-linked LeX or sialyl LewisX (sLeX).

(-)-Shikimic Acid as a Chiral Building Block for the Synthesis of New Cytotoxic 6-Aza-Analogues of Angucyclinones.

Project description:We describe the syntheses of nine new angucyclinone 6-aza-analogues, achieved through a hetero Diels-Alder reaction between the shikimic acid derivative-azadiene 13, with different naphthoquinones. The cytotoxic activity of the new synthesized compounds and five angucyclinones, previously reported, was evaluated in vitro against three cancer cell lines: PC-3 (prostate cancer), HT-29 (colon cancer), MCF-7 (breast cancer), and one non-tumoral cell line, human colon epithelial cells (CCD841 CoN). Our results showed that most 6-azadiene derivatives exhibited significant cytotoxic activities, which was demonstrated by their IC50 values (less than 10 μM), especially for the most sensitive cells, PC-3 and HT-29. From a chemical point of view, depending on the protected group of ring A and the pattern of substitution on ring D, cytotoxicity elicited these compounds, in terms of their potency and selectivity. Therefore, according to these chemical features, the most promising agents for every cancer cell line were 7a, 17, and 19c for PC-3 cells; 7a, 17, and 20 for HT-29 cells, and 19a for MCF-7 cells.
