Structural characterization of carbohydrates by mass spectrometry necessitates a detailed understanding of their gas phase behavior, particularly for protonated carbohydrates that can undergo complex structural rearrangements during fragmentation. Here we utilize tandem mass spectrometry, isotopic labeling, gas-phase hydrogen/deuterium exchange, and ion mobility measurements to characterize structures of the various product ions of protonated N-acetylhexosamines. Following the facile loss of the reducing end hydroxyl group, we identify two primary fragmentation pathways. Detailed mapping of each step in the fragmentation pathway provides new insight into the mechanisms that drive collision-induced dissociation of protonated carbohydrates. Several of the smaller fragment ions are mixtures of structural isomers, and the relative distributions of these structures reveals information about the stereochemistry of the precursor molecule.

Lectin from the seeds of Dioclea lasiophylla (DlyL) was purified in a single step by affinity chromatography on a Sephadex G-50 column. DlyL strongly agglutinated rabbit erythrocytes and was inhibited by monosaccharides (D-mannose and alpha-methyl-Dmannoside) and glycoproteins (ovalbumin and fetuin). Similar to other Diocleinae lectins, DlyL has three chains, alpha, beta and gamma, with mass of 25,569 ± 2, 12,998 ± 1 and 12,588 ± 1 Da, respectively, and has no disulfide bonds. The hemagglutinating activity of DlyL was optimal in pH 8.0, stable at a temperature of 70 C and decreased in EDTA solution, indicating that lectin activity is dependent on divalent metals. DlyL exhibited low toxicity on Artemia sp. nauplii, but this effect was dependent on the concentration of lectin in solution. DlyL immobilized on cyanogen bromide-activated Sepharose 4B bound 0.917 mg of ovalbumin per cycle, showing the ability to become a tool for glycoproteomics studies.

Galactokinases (GalKs) have attracted significant research attention for their potential applications in the enzymatic synthesis of unique sugar phosphates. The galactokinase (GalKSpe4) cloned from Streptococcus pneumoniae TIGR4 presents a remarkably broad substrate range including 14 diverse natural and unnatural sugars. TLC and MS studies revealed that GalKSpe4 had relaxed activity towards galactose derivatives with modifications on the C-6, 4- or 2-positions. Additionally, GalKSpe4 can also tolerate glucose while glucose derivatives with modifications on the C-6, 4- or 2-positions were unacceptable. More interestingly, GalKSpe4 can phosphorylate l-mannose in moderate yield (43%), while other l-sugars such as l-Gal cannot be recognized by this enzyme. These results are very significant because there is rarely enzyme reported that can phosphorylate such uncommon substrates as l-mannose.

Analogues of a bipartite compound, dequalinium (DECA) (quinolinium, 1,1′-(1,10-decanediyl)bis(4-amino-2-methyl diiodide)), were tested for inhibition of protein kinase Calpha (PKCalpha). In vitro assays of monomeric and dimeric analogues support a model in which DECA inhibits PKCalpha by an obligatory two-point contact, a unique mechanism among PKC inhibitors. The presence of unsaturation in the center of the C10-alkyl linker produced geometric isomers with different inhibitory potencies: cis IC50 = 52 ± 12 muM and trans IC50 = 12 ± 3 muM, where the trans isomer was equipotent to that of the saturated C10-DECA. DECA analogues with longer, saturated linkers (C12, C14, or C16) exhibited enhanced inhibitory potencies which reached a plateau with the C14-linker (IC50 = 2.6 ± 0.2 muM). Metastatic melanoma cells treated with 250 nM C12-, C14-, or C16-DECA and irradiated with long-wave UV light (which causes irreversible inhibition of PKCalpha by DECA) confirmed the linker-dependent inhibition of intracellular PKCalpha activity.

Insect chitinolytic beta-N-acetylhexosaminidase OfHex1, from the agricultural pest Ostrinia furnacalis (Guenee), is considered as a potential target for green pesticide design. In this study, rational molecular design and optimization led to the synthesis of compounds 15r (Ki = 5.3 muM) and 15y (Ki = 2.7 muM) that had superior activity against OfHex1 than previously reported lead compounds. Both compounds 15r and 15y had high selectivity toward OfHex1 over human beta-N-acetylhexosaminidase B (HsHexB) and human O-GlcNAcase (hOGA). In addition, to investigate the basis for the potency of glycosylated naphthalimides against OfHex1, molecular docking and molecular dynamics simulations were performed to study possible binding modes. Furthermore, the in vivo biological activity of target compounds with efficient OfHex1 inhibitory potency was assayed against Myzus persicae, Plutella xylostella, and O. furnacalis. This present work indicates that glycosylated naphthalimides can be further developed as potential pest control and management agents targeting OfHex1.

In this paper, we report the synthesis of carbohydrate-derived 1,7-enynes and subsequent metathesis to yield polyhydroxylated 1-vinylcyclohexenes. For example, we converted D-glucose 2 to the (6,7)-dideoxy-D-gluco-hept-6-ene-pyranose 7, which led to the desired 1,7-enyne 16. The ring-closing metathesis of this 1,7-enyne 16 with the second generation Grubbs catalyst, under Mori’s conditions, gave the corresponding polyhydroxylated 1-vinylcyclohexene 25 in 76% yield. The conversion of several aldohexoses into polyhydroxylated 1-vinylcyclohexenes was carried out with satisfying yields. We report also the synthesis of two carbohydrate-derived ethyl 8-yn-2-enoates from D-glucose derivatives.

Condensation of 1,3-diketones with unprotected aldoses in water, under mildly alkaline conditions, provides a convenient and effective route to C-glycosidic ketones in high yields. Reactions usually proceed with high beta-‘anomeric’ stereoselectivity because product composition is determined by thermodynamic control. Mechanistically, the condensation follows a typical Knoevenagel scheme, after which an intramolecular oxa-Michael cyclization determines C-glycoside configuration by following an exo- or endo-trig pathway. With open-chain 1,3-diketones, an ensuing retro-Claisen fragmentation occurs to furnish simple glycosyl monoketones. The C-glycosides then slowly further dehydrate under the reaction conditions to give 2,5-disubstituted furans.
