Owing to the expression of more than one type of galectin in animal tissues, the delineation of the functions of individual members of this lectin family requires the precise definition of their carbohydrate specificities. Thus, the binding properties of chicken liver galectin (CG-16) to glycoproteins (gps) and Streptococcus pneumoniae type 14 polysaccharide were studied by the biotin/avidin-mediated microtitre-plate lectin-binding assay and by the inhibition of lectin-glycan interactions with sugar ligands. Among 33 glycans tested for lectin binding, CG-16 reacted best with human blood group ABO (H) precursor gps and their equivalent gps, which contain a high density of D- galactopyranose(beta1-4)2-acetamido-2-deoxy-D-glucopyranose [Gal(beta1-4)GlcNAc] and Gal(beta1-3)GlcNAc residues at the non-reducing end, but this lectin reacted weakly or not at all with A-, H-type and sialylated gps. Among the oligosaccharides tested by the inhibition assay, the tri-antennary Gal(beta1-4)GlcNAc (Tri-II) was the best. It was 2.1 × 103 nM and 3.0 times more potent than Gal and Gal(beta1-4)GlcNAc (II)/Gal(beta1-3) GlcNAc(beta1-3)Gal(beta1-4)Glc (lacto-N-tetraose) respectively. CG-16 has a preference for the beta-anomer of Gal at the non-reducing end of oligosaccharides with a Gal(beta1-4) linkage > Gal(beta1-3) ? Gal(beta1-6). From the results, it can be concluded that the combining site of this agglutinin should be a cavity type, and that a hydrophobic interaction in the vicinity of the binding site for sugar accommodation increases the affinity. The binding site of CG-16 is as large as a tetrasaccharide of the beta-anomer of Gal, and is most complementary to lacto-N-tetraose and Gal(beta1-4)GlcNAc related sequences.

The enantioselective enzymatic desymmetrization (EED) of various 3-arylglutaric anhydrides 1 with alcohols in organic media has been studied. The effect of the solvent on the stereochemical outcome of the reaction was investigated in detail. The amount of biocatalyst was optimized, and the possibility of its re-use was tested. The first example of the EED of 3-substituted glutaric anhydrides with esters as nucleophiles is reported.

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.category: Tetrahydropyrans, you can also check out more blogs about53911-68-5

Control of stem rust disease of wheat was investigated using different combinations of Trichoderma spp. and arbuscular mycorrhizal (AM) fungi. Impact of the application of T. harzianum HL1 and T. viride HL5, singly or in combination, on the uredospores germination of Puccinia graminis Pers. f. sp. tritici was assessed in vitro. The combined spore suspension of both isolates showed the superiority over the others in this regard. Observations of the scanning electron microscopy confirmed this result. Using a GC-MS system, the chemical constitution of the culture filtrates of T. harzianum HL1 and T. viride HL5 was identified. Under the greenhouse conditions, application of AM fungi and Trichoderma spp. significantly reduced the disease measures, induced the peroxidase and polyphenol oxidase enzymes, increased the total phenol content and improved the tested growth and yield parameters. Based on their efficiency and eco-safety, we can recommend the use of this combination in controlling stem rust disease of wheat.

An efficient and practical one-pot method for the synthesis of novel diversified sugar derived dihydro-quinazolino[4,3-b]quinazolin-8-ones has been reported. Various protected sugar hemiacetals were used to synthesize the hybrid tetracyclic ring system. The one-step reductive transformation of 2-(2-nitrophenyl)-3H-quinazolin-4-one with different sugar hemiacetals furnished the desired tetracyclic product in good yields and with high purity.

In this study, a white-brined cheese made from goat milk (from the Greek native breed Capra prisca) was manufactured using the technology based on Feta cheese-making. The composition, proteolysis, volatiles and sensory properties of this cheese were studied at different ripening days. No significant differences were found for the main physicochemical parameters of the cheese during ripening and storage. Retinol and alpha-tocopherol, the fat-soluble vitamins decreased after 60 d of ripening. Proteolysis, as assessed by measuring the levels of soluble nitrogen, increased with time. Free fatty acids were the most abundant group of chemical compounds found in the cheese. Most of the volatiles (apart from free fatty acids) reached their highest levels after 60 days of ripening. The cheese received satisfactory scores during organoleptic evaluation.
