Lanthanum trifluoromethane-sulfonate-catalyzed facile synthesis of per-O-acetylated sugars and their one-pot conversion to S-aryl and O-alkyl/aryl glycosides

Lanthanum trifluoromethanesulfonate-catalyzed solvent-free per-O-acetylation with stoichiometric acetic anhydride proceeds in high yield (95%-99%) to afford exclusively pyranose products as anomeric mixtures. Subsequent anomeric substitution employing borontrifluoride etherate and thiols or alcohols furnished the corresponding 1,2-trans-linked thioglycosides and O-glycosides, respectively, in good to excellent overall yield (75%-85%). Alternatively, reaction of free sugars in neat alcohol employing the same catalyst at elevated temperature gives the corresponding 1,2-cis-linked O-glycosides (along with 1,2-trans-linked glycosides as minor product) in good yield (73%-80%). Anomeric mixtures of compounds thus produced were characterized as their per-O-acetylated derivatives.

Synthesis of multivalent neoglyconjugates of MUC1 by the conjugation of carbohydrate-centered, triazole-linked glycoclusters to MUC1 peptides using click chemistry

The efficient synthesis of multivalent neoglycoconjugates of MUC1 is reported, which utilizes Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuACC) of azide-functionalized GlcNAc-centered neoglycotetrasaccharide clusters to the MUC1 peptide sequence that was equipped with a propargylglycine residue for “click chemistry”?. In turn the azido-GlcNAc-centered neoglycoclusters were assembled by reaction of a GlcNAc core containing peripheral propargyl functionalities with an appropriate azido-functionalized monosaccharide. The resulting suitably substituted tetrasaccharyl triazole cluster can be easily appended to a range of acetylene-functionalized peptides to produce neoglycoconjugates of biologically important glycopeptides. As proof of principle, the click neoglycoclusters prepared herein were ligated to the MUC1 peptide sequence.

Tetrahydro-isoquinoline-based factor Xa inhibitors

Derivatives of (2-amidino-1,2,3,4-tetrahydro-isoquinolin-7- yloxy)phenylacetic acid (TIPAC) were developed as inhibitors of factor Xa (fXa). The compounds are prepared using 15 synthetic steps on average. The most potent compounds (14, 17, 22-26) display inhibition constants of K(i) = 21-55 nM but do not inhibit thrombin (K(i) = 5-> 100 muM) and only weakly inhibit trypsin (K(i) = 0.08-5 muM). They bear a second basic moiety, e.g., substituted 1-(iminomethyl)piperidines, which is linked to C-4 of the phenyl group of TIPAC via an oxygen atom. The inhibition constants of these compounds are almost independent of the size of the (iminomethyl)piperidine substituent. Due to the fact that fXa displays two cation binding sites, namely, the S1 and S4 sites, in principle two binding modes are conceivable for the novel dibasic fXa inhibitors. Molecular modeling experiments based on the X-ray structures of uninhibited fXa and the DX-9065a/fXa complex were carried out. The results taken together with the inhibition constants clearly favor one binding mode: the tetrahydro-isoquinoline fills the S1 pocket even better than the naphthalene moiety of DX-9065a, and the (iminomethyl)piperidine residues occupy the S4 site.

LC-MS-based metabolomics reveals metabolic signatures related to glioma stem-like cell self-renewal and differentiation

Gliomas are the most common and lethal primary malignant brain tumors. Recent studies implicate an important role for a rare population of glioma stem cells (GSCs) in glioma maintenance and recurrence. New therapeutic strategies are desperately needed requiring insights into the biological and molecular mechanisms underlying the self-renewal and differentiation of GSCs. We now investigate the metabolic signatures of three glioma cell lines with different stemness using a liquid chromatography-mass spectrometry (LC-MS)-based metabolomics approach. Cellular metabolites differentially expressed in U87MG stem-like cells (SLCs) relative to U87 malignant glioma cells (GCs) and U87MG stem-like cell differentiation cells (SLCDCs) were identified. The specific and significant alterations including nucleotide metabolism, glycerophospholipid metabolism, glutathione metabolism, carnitine metabolism and tryptophan metabolism were characterized. Cell function assays were further used to evaluate the self-renewal ability of SLCs treated with differential metabolites, indicating that these metabolites are involved in the maintenance of stemness. The results provide valuable information on the association of the significantly altered metabolites and metabolic pathways with SLC self-renewal and differentiation.
