The syntheses of two 1,4-anhydro-D-xylitol heteroanalogues (8 and 9) of the naturally occurring sulfonium ion, salacinol (3), containing a sulfur or nitrogen atom in the ring are described. Salacinol (3) is one of the active principles in the aqueous extracts of Salacia reticulata that are traditionally used in Sri Lanka and India for the treatment of Type 2 diabetes. The synthetic strategy relies on the nucleophilic attack of sulfur or nitrogen analogues of 1,4-anhydro-D-xylitol at the least-hindered carbon of 2,4-O-benzylidene-L-erythritol-1,3-cyclic sulfate.

Abstract:
Praseodymium(III) NMR shift reagent, which is an upfield shift reagent, is focused on for assessment of enantiomeric excess and resolution of methyl sulfonium ions. A series of alkylmethylphenylsulfonium ions were analyzed, where alkyl is ethyl (I), butyl(H), octyl (III), and benzyl(IY). The praseodymium agent gives base-lined resolution of the ortho hydrogens resonance for I and IH. All spectra are strongly temperature-dependent. I is shifted more than ED, consistent with a steric effect. Assignments for I were made by gradually increasing the concentration of the shift reagent and by analyzi

Hur elektrolytlösningar interagerar med laddade ytor är viktigt för många fenomen. I detta arbete undersöktes samspelet mellan flera joner med en negativt laddad yta som exponerade sulfonat funktionella grupper mot lösning. Särskild vikt lades på deprotoneringsbeteendet vid ytan. Samspelet mellan olika joner och sulfonatgruppen hade inte tidigare beaktats ur ett molekylärt perspektiv. Här användes ett Langmuir-monolager bestående av dokosan-1-sulfonsyra deponerat på olika elektrolytlösningar som modellsystem.

Tuberculosis (TB) is the disease arising from infection by Mycobacterial tuberculosis and kills millions of people every year. Difficulties in the treatment of TB and the emergence of multiple-drug resistant and extreme-drug resistant M. tuberculosis strains have increased interest in finding new antimycobacterial agents. The cell wall of mycobacteria is essential for the survival of these bacteria and enzymes involved in its assembly are key targets for anti-mycobacterial chemotherapy. One of the largest components of the cell wall is the arabinogalactan, which is composed of arabinofurano

The porous structure of chitosan matrices could make the copper ion solution flowing though the matrices. The copper ions would be easily caught by the amino groups of chitosan matrices or sulfonic groups of ion exchange resins. The specific surface area of chitosan mixed matrices are 72.2
