A green synthesis for beta-(1?3) galactosyldisaccharides that combines the use of a biodegradable biocatalyst, aqueous solutions, and solvent recycling (renewable and derived from biomass) has been developed. The use of biomass-derived solvents allows good catalytic activity in the synthesis of Gal-beta-d-(1?3)GlcNAc and Gal-beta-d-(1?)3GalNAc (99% and 95% yields respectively) with beta-Gal-3-NTag beta-galactosidase, preventing hydrolytic activity and with full regioselectivity. This represents a considerable improvement over the use of an aqueous buffer or conventional organic solvents. Furthermore, reaction scaling up and biosolvent recycling are feasible without losing catalytic action. In order to understand the role of these green solvents in the enzyme’s synthetic behaviour, different structural studies were performed (fluorescence and molecular modelling) in the presence of some selected biosolvents to conclude that the presence of green biosolvents in the reaction media modifies the enzyme’s tertiary structure allowing better substrate disposition in the active site, most probably due to solvation effects, explaining the behaviour observed.

Electric Literature of 31608-22-7, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran, molecular formula is C9H17BrO2. In a patent, introducing its new discovery.

A concise route for construction of the ACDE ring skeleton in calyciphylline A type alkaloids was developed using an intramolecular [5+2] cycloaddition reaction of an oxidopyrylium species bearing a tetrasubstituted olefin. Key to the success of this reaction was the combination of acid and base, which accelerated the construction of this skeleton containing a spiro ring and vicinal quaternary carbon centers. The resultant tricyclic ADE ring compound was converted to an ACDE ring model through C?H oxidation and an aza-Wittig reaction.

beta-N-Acetylhexosaminidase (EC 3.2.1.52) was purified from the culture filtrate of Pycnoporus cinnabarinus to homogeneity by polyacrylamide disc gel electrophoresis.The ratio of beta-GlcNAcase activity to beta-GalNAcase activity remained constant during the purification process.The molecular weight of this enzyme was estimated to be about 120,000 by gel filtration, and the isoelectric point was at about pH 5.4.The optimum pH was at 2.2 for pNPGlcNAc and around 3.7 for pNPGalNAc.The enzyme was relatively stable at acid pH range of 2-4 (for 45 hr at 5 deg C) and below 45 deg C (for 10 min at pH 2.8).The enzyme hydrolysed chito-oligosaccharides, such as N,N-diacetylchitobiose, N,N,N-triacetylchitotriose and N,N,N,N-tetraacetylchitotetraose.

A simple, rapid and highly regioselective green protocol has been developed for the halogenation of aromatic systems with N-halosuccinimides using room temperature ionic liquids (ILs) as novel and recyclable reaction media to produce the corresponding halogenated aromatic compounds in high to quantitative yields. N-Halosuccinimides show enhanced reactivity in ionic liquids thereby reducing the reaction times dramatically and improving the yields substantially.

A highly convergent strategy for the synthesis of several derivatives of the lipid A of Rhizobium sin-1 has been developed. The synthetic derivatives are 2-aminogluconate 3 and 2-aminogluconolactone 4, both of which lack C-3 acylation. These derivatives were obtained by the preparation of disaccharides in which the two amino groups and the C-3? hydroxy group could be modified individually with acyl or beta-hydroxy fatty acyl groups. Detailed NMR spectroscopy and MS analysis of 3 and 4 revealed that, even under neutral conditions, the two compounds equilibrate. The synthetic compounds lack the proinflammatory effects of Escherichia coli lipopolysaccharide (LPS), as indicated by an absence of tumor necrosis factor production. Although 3 and 4 were able to antagonize E. coli LPS, they were significantly less potent than the synthetic compound 2, which is acylated at C-3, and R. sin-1 LPS; these results indicate that the beta-hydroxy fatty acyl group at C-3 contributes to the antagonistic properties of R. sin-1 LPS. Based on a comparison of the biological responses of the synthetic lipid A derivatives with those of the R. sin-1 LPS and lipid A, the 3-deoxy-D-manno-octulosonic moieties appear to be important for the optimal antagonization of enteric LPS-induced cytokine production.

A versatile green gelator suitable for multiple applications is reported. Gelation of organic solvents in a significantly low gelation time (<5 s) is achieved. The effect of cooling and sonication on gelation time is investigated. Apart from organic solvents, the gelator is capable of forming gels with fuel oils such as diesel and petrol also; therefore, it has been utilized for the separation of oil from an oil/water mixture through selective gelation of the oil. The gelator was also found to be capable of forming hydrogels through rational control of the reaction conditions. Hydrogel prepared using the gelator was further explored as reaction medium for the growth of gold nanoparticles. In the case of nanoparticle synthesis, the gelator served not only as a capping agent but also as a reducing agent. By taking advantage of the dual functionality of the gelator (capping and reducing agent), nanoparticles of both gold and silver were prepared in fluid medium also. The organogel, prepared using toluene and gelator, was utilized for the removal of the waterborne synthetic dye rhodamine B.
