Co-crystallised alpha- and beta-anomers of 2,3,4,6-tetra-acetyl-D- glucopyranose, in which the alpha- and beta-anomers are randomly distributed in the hydrogen-bonded chains of molecules

A co-crystallised sample of alpha- and beta-2,3,4,6-tetra-O-acetyl-d- glucopyranose [alpha:beta = 1:2.86(8)], (alpha,beta-1), has been isolated from a solution of 2,3,4,6-tetra-O-acetyl-d-glucopyranose in moist ethyl acetate/diethyl ether. In contrast, pure beta-2,3,4,6-tetra-O-acetyl-d- glucopyranose, (beta-1) was isolated on crystallisation from diethyl ethyl/petroleum ether. Species (alpha,beta-1) is a solid solution in which approximately one in four of the molecules in the beta-form is randomly substituted by a molecule of the alpha-anomer. The hydrogen bonded zig-zag chain connectivity of the pure beta-anomer is maintained in the solid solution along the b direction. Since the parent d-glucopyranose compounds differ in their molecular packing and, therefore in structure, the solid solution phenonmenon in the case of their tetraacetyl derivatives is unexpected. Compound (beta-1) and the (alpha,beta-1) solid solution crystallize in the orthorhombic space group P212121: a = 7.8612(4) A, b = 10.2045(5) A, c = 20.7362(11) A, and Z = 4 for (beta-1) at 120(2)K; and a = 7.9674(5) A, b = 10.2547(4) A, c = 21.1565(10) A, and Z = 4 for (alpha,beta-1) at 291(2) K.

Abberant immunoglobulin g glycosylation in rheumatoid arthritis by LTQ-ESI-MS

Aberrant glycosylation has been observed in many autoimmune diseases. For example, aberrant glycosylation of immunoglobulin G (IgG) has been implicated in rheumatoid arthritis (RA) pathogenesis. The aim of this study is to investigate IgG glycosylation and whether there is an association with rheumatoid factor levels in the serum of RA patients. We detected permethylated N-glycans of the IgG obtained in serum from 44 RA patients and 30 healthy controls using linear ion-trap electrospray ionization mass spectrometry (LTQ-ESI-MS), a highly sensitive and efficient approach in the detection and identification of N-glycans profiles. IgG N-glycosylation and rheumatoid factor levels were compared in healthy controls and RA patients. Our results suggested that total IgG purified from serum of RA patients shows significantly lower galactosylation (p = 0.0012), lower sialylation (p < 0.0001) and higher fucosylation (p = 0.0063) levels compared with healthy controls. We observed a positive correlation between aberrant N-glycosylation and rheumatoid factor level in the RA patients. In conclusion, we identified aberrant glycosylation of IgG in the serum of RA patients and its association with elevated levels of rheumatoid factor. Do you like my blog?

Selective N-deacetylation of p-nitrophenyl N,N’-diacetyl-beta-chitobioside and its use to differentiate the action of two types of chitinases

We report the synthesis of a novel compound for chitinase assays, p-nitrophenyl 2-acetamido-4-O-(2-amino-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-beta-D-glucopyranoside [GlcNGlcNAc-pNP] by selective N-deacetylation of p-nitrophenyl 2-acetamido-4-O-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-beta-D-glucopyranoside [(GlcNAc)2-pNP] using a purified chitin deacetylase isolated from Colletotrichum lindemuthianum ATCC 56676. FABMS, 1H NMR, and 13C NMR analyses confirmed the structure of this new compound. This disaccharide derivative can be used to distinguish special chitinases that effectively remove partially deacetylated parts of substrates within a mixture of chitinases which degrades (GlcNAc)2-pNP.

Catalytic Carbonylative Spirolactonization of Hydroxycyclopropanols

A palladium-catalyzed cascade carbonylative spirolactonization of hydroxycyclopropanols has been developed to efficiently synthesize oxaspirolactones common to many complex natural products of important therapeutic value. The mild reaction conditions, high atom economy, broad substrate scope, and scalability of this new method were highlighted in expedient total syntheses of the Turkish tobacco natural products alpha-levantanolide and alpha-levantenolide in two and four steps, respectively. The hydroxycyclopropanol substrates are readily available in one step via a Kulinkovich reaction of the corresponding lactones. Mechanistic studies utilizing high-resolution electrospray ionization mass spectrometry (ESI-MS) identified several key intermediates in the catalytic cycle, as well as those related to catalyst decomposition and competitive pathways.

SYNTHESIS AND REACTIONS OF D-GLUCOPYRANOSYL ESTERS OF PHENYLALANINE AND TYROSINE: A STUDY OF THE DIAZOMETHANE-CATALYSED 1->2 ACYL MIGRATION OF THE N-ACYLATED alpha-D ANOMERS

The fully benzylated alpha- and beta-D-glucopyranosyl esters of N-benzyloxycarbonyl- and N-tert-butoxycarbonyl-L-phenylalanine (1 and 5, respectively) have been converted into 1-O-(L-phenylalanyl)-alpha- and -beta-D-glucopyranose, which were isolated as trifluoroacetate salts (2alpha and 2beta).On dissolution in water, 1-O--alpha-D-glucopyranose (6a) gave the anomerised C-2 isomer 8 and hydrolysis products of 6alpha.Treatment of 6alpha with N,N-dimethylformamide-ethereal diazomethane gave the 2-O-acyl derivative 8alpha (>80percent). 1-O-(L-Tyrosyl)-alpha-(12alpha) and -beta-D-glucopyranose (12beta), isolated as the trifluoroacetate salts, were prepared from 2,3,4,6-tetra-O-benzyl-1-O--alpha- and -beta-D-glucopyranose (10) and characterised as the N-acetyl- (13) and tetra-acetate derivatives (14).Treatment of 13alpha with diazomethane caused extensive hydrolysis, but some rearrangement into the 2-O-acyl derivative 15alpha, which was characterised as crystalline 1,3,4,6-tetra-O-acetyl-2-O-(N-acetyl-O-acetyl-L-tyrosyl)-alpha-D-glucopyranose (16alpha).The foregoing 1->2 acyl migrations and hydrolyses are competitive reactions, the relative rates of which are strongly affected by reaction temperature and the nature of the acyl group.
