The glycosylation reactions with glycosyl phosphites in the presence of catalytic amounts of TMSOTf at low temperature have been studied with different donors and acceptors for the synthesis of several glycosides, including O-glycosides, S-glycosides, C-glycosides, and glycopeptides.Mechanistic investigations of the reactions indicate that the glycosyl phosphite is activated by either TfOH or TMSOTf, depending on how the substrates are mixed.When the acceptor is treated with TMSOTf first, the glycosyl phosphite is activated by the resulting TfOH.The glycosyl phosphite can also be activated by TMSOTf directly.The best result is, however, to mix the acceptor and TMSOTf first, followed by addition of the glycosyl phosphite.

Clanis bilineata larvae are widely consumed in China. In this study, chitooligosaccharides were prepared from C. bilineata larvae skin by demineralisation, deproteination, washing, drying, deacetylation, hydrolysis using commercial alpha-amylase, filtration, setting the preparation at approximately 15% (w/v), precipitation with 6 volumes of ethanol, and drying at 60 C for 2 h. The optimal hydrolysis conditions were determined as follows: pH 5.5; temperature, 55 C; enzyme amount, 40. mg/(g chitosan); reaction time, 4 h. The Fourier transform infrared spectra revealed that chitooligosaccharides with a degree of polymerisation in the range of 2-8 were the main component of the resulting product, with the chitooligosaccharide content and yield being 95.8% and 96.2% (w/w), respectively. The resulting product showed high antibacterial activity compared with the original chitosan.

The carbohydrate-binding properties of Castanea crenata agglutinin (CCA) were investigated by an enzyme-linked lectin absorbent assay. The binding ability of each carbohydrate was compared using IC50 values. CCA exhibited mannose/glucose specificity, as observed with many mannose-binding jacalin-related lectins. For oligosaccharides containing glucose, it has been shown that the degree of polymerization and the linkage mode of glucose residues have no effect on CCA-carbohydrate interaction; thus, only the non-reducing end glucose unit in glucooligosaccharides may be involved in the interaction with CCA. Among mannooligosaccharides, CCA strongly recognized alpha-(1?3)-d- Man-[alpha-d-Man-(1?6)]-d-Man, which is a core in N-linked carbohydrate chains. By considering the results with glycoproteins, it is likely that CCA binds preferentially to mono- or non-sialylated biantennary carbohydrate chains. We also obtained Kd values by analysis of the dependency of the IC50 on CCA concentration, based on the hypothesis that CCA has a single binding site or two equivalent binding sites. The estimated Kd values for mannose, glucose and alpha-(1?3)-d-Man-[alpha-d-Man- (1?6)]-d-Man were 2.39, 7.19 and 0.483 mM, respectively. The relative binding abilities showed good agreement with the relative inhibition intensities. Isothermal calorimetric titration was carried out to directly estimate the dissociation constants of CCA for mannose and for alpha-d-Man-(1?3)-d-Man. The values were 2.34 mM for mannose and 0.507 mM alpha-d-Man-(1?3)-d-Man. These results suggest that the relative inhibition intensity represents the ratio of Kd values and that CCA has a single or two equivalent binding sites.

The lack of efficacy of current antibacterials to treat multidrug resistant bacteria poses a life-threatening alarm. In order to develop enhancers of the antibacterial activity, we carried out a medicinal chemistry campaign aiming to develop inhibitors of enzymes that synthesise cysteine and belong to the reductive sulphur assimilation pathway, absent in mammals. Previous studies have provided a novel series of inhibitors for O-acetylsulfhydrylase?a key enzyme involved in cysteine biosynthesis. Despite displaying nanomolar affinity, the most active representative of the series was not able to interfere with bacterial growth, likely due to poor permeability. Therefore, we rationally modified the structure of the hit compound with the aim of promoting their passage through the outer cell membrane porins. The new series was evaluated on the recombinant enzyme from Salmonella enterica serovar Typhimurium, with several compounds able to keep nanomolar binding affinity despite the extent of chemical manipulation.

Since palladium-catalysts have strong abilities for both hydrogenation of nitro-group and hydrogenolysis of benzylamine, they have a much lower chemoselectivity for the hydrogenation of (N,N-disubstituted aminomethyl)nitrobenzenes. In this article, component stable Pd-Ni bimetallic nanoparticles were prepared by simply heating RANEY-Ni and Na2PdCl4 together in water. They demonstrated novel synergistic effects when they were used as a bimetallic catalyst, by which a highly efficient and chemoselective hydrogenation of (N,N-disubstituted aminomethyl)nitrobenzenes to (N,N-disubstituted aminomethyl)anilines was achieved.
