Synthesis and cholera toxin binding properties of multivalent GM1 mimics

Dendrimers based on the 3,5-di-(2-aminoethoxy)-benzoic acid branching unit were used to attach multiple copies of a GM1 mimic for inhibition of cholera toxin binding. Systems up to octavalent were synthesized along with relevant reference compounds that contained in one case the ligand in a monovalent format and in another case the scaffold but not the ligand. Using a surface plasmon resonance inhibition assay the prepared inhibitors showed good inhibition. While the monovalent GM1 mimic showed the expected inhibition in the 200 muM range the multivalent scaffolds led to increased binding. The tetravalent compound was shown to be 440-fold more potent than its monovalent counterpart. The octavalent analog, however, was the most potent compound as determined using an ELISA assay.

Elastic-Plastic Transformation of Polyelectrolyte Complex Hydrogels from Chitosan and Sodium Hyaluronate

Hydrogels formed by polyelectrolyte complexation (PEC) of oppositely charged biopolymers, free of any chemical additives, are promising biomaterials. In this work, the mechanical behavior of hydrogels consisting of positively charged chitosan and negatively charged sodium hyaluronate (HA) at balanced charge composition is investigated. These hydrogels exhibit strong tensile strain and strain rate dependence. They are elastic-like, independent of the strain rate at small strain, but exhibit plastic-like behavior above the yield point by showing a monotonous decrease of the stress. The cyclic tensile test demonstrates that these hydrogels exhibit small and quickly recoverable hysteresis in the elastic-like region but large and partially recoverable hysteresis above the yield point. The stress relaxation experiment shows a plateau in the reduced stress followed by an abrupt fracture, and the time to failure decreases exponentially with increasing applied step strain. Such elastic-to-plastic-like transformation of the biopolymer PEC gels is quite different from the behaviors of PEC hydrogels formed by oppositely charged vinyl-type synthetic polyelectrolytes due to the difference in flexibility, charge density, and ionic bond strength of these polymers.

Biotechnological value of Moringa oleifera seed cake as source of insecticidal lectin against Aedes aegypti

Moringa oleifera seed cake, which is the coproduct of oil extraction, may be a source of lectin. This study reports the purification of a lectin from M. oleifera cake (WSMoLC) and the determination of its effect on larvae, eggs and oviposition of Aedes aegypti. WSMoLC was isolated (purification fold: 3573) by treatment of water extract with ammonium sulphate (60%) and chromatography of lectin-rich fraction on chitin column. In gel trypsin, digestion followed by mass spectrometry revealed the similarity of WSMoLC peptides with other M. oleifera seed proteins. WSMoLC exerted deleterious effects on larvae (LC50: 0.89?mg/mL) and eggs (EC50: 0.14?mg/mL) and served as an oviposition-stimulant at the concentration of 0.1?mg/mL. Larvicidal activity may be linked to lectin resistance to digestion and stimulatory effect on the activities of protease and alpha-amylase at larvae gut. Furthermore, the larvae did not start to express different enzymes in response to lectin effect. This study adds value to M. oleifera seed cake as a source of insecticidal lectin with high potential to be used in control of A. aegypti because, at the same time that it stimulates the oviposition by females, it could kill the eggs or larvae that may arise from them.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C8H15NO6, you can also check out more blogs about14215-68-0

Glycosylation analysis of interleukin-23 receptor: Elucidation of glycosylation sites and characterization of attached glycan structures

Interleukin-23 (IL-23) is a heterodimeric cytokine, a central factor in chronic/autoimmune inflammation. It signals through a heterodimeric receptor consisting of IL-23r, which is heavily glycosylated. The structural characterization of IL-23r has not been reported. In this work, glycosylation profiles of soluble recombinant human IL-23r (rhIL-23r) were established using mass spectrometry (MS), which included defining glycosylation sites, degree of glycosylation occupancy of each site and structure of attached oligosaccharides. Specifically, precursor ion scan of oxonium ion protonated N-acetylglucosamine (GlcNAc+) (m/z 204) was performed using a triple quadrupole MS instrument to locate the retention time of glycopeptides. Both the glycopeptides and their corresponding deglycosylated forms in each collected HPLC fraction were studied by liquid chromatography-tandem mass spectrometry (LC-MS/MS) (LTQ-Orbitrap) for glycosylation site profiling. The attached glycan structures were elucidated by collision-induced dissociation (CID) fragmentation of target glycopeptides in combination with accurate mass measurement. Eight glycosylation sites were identified on IL-23r (Asn24, Asn209, Asn239, Asn157, Asn118, Asn250, Asn58 and Asn6). Most of the glycosylation sites were > 95% occupied except Asn250 and Asn6. Those two sites were 88% and 45% occupied by estimation from trypsin digestion and were 55% and 42% occupied from LysC digestion. Multiple glycoforms were observed in IL-23r. Most of them were bi-, tri- or tetra-antennary complex type structures with fucose and sialic acid. High mannose and hybrid type glycans were only observed on Asn157. The structural characterization on IL-23r glycosylation provides useful information for better understanding of the biological function of IL-23r. Copyright

Non-enzymatic reaction of glycosyl oxazoline with peptides

Recently, a number of chemoenzymatic strategies have been explored for achieving preparation of homogeneous glycopeptides and glycoproteins, especially by using endoglycanases and glycosyl oxazolines. However, concomitant occurrence of non-enzymatic reactions has been reported, but no further characterization of the byproducts was conducted. In this work, we made an attempt to identify the side product by using model substrates. Analysis of the product allowed us to propose that the oxazoline ring was attacked by the amino group of lysine, leading to the formation of disubstituted acetamidine.

Artificial Cysteine S-Glycosylation Induced by Per-O-Acetylated Unnatural Monosaccharides during Metabolic Glycan Labeling

The unexpected, non-enzymatic S-glycosylation of cysteine residues in various proteins by per-O-acetylated monosaccharides is described. This artificial S-glycosylation greatly compromises the specificity and validity of metabolic glycan labeling in living cells by per-O-acetylated azido and alkynyl sugars, which has been overlooked in the field for decades. It is demonstrated that the use of unacetylated unnatural sugars can avoid the artifact formation and a corrected list of O-GlcNAcylated proteins and O-GlcNAc sites in HeLa cells has been assembled by using N-azidoacetylgalactosamine (GalNAz).
