SPINOSIDES A AND B. TWO CYTOTOXIC CUCURBITACIN GLYCOSIDES FROM DESFONTAINIA SPINOSA

Fractionation of the active ethanol extract of Desfontainia spinosa based on cytotoxicity has led to the discovery of three new derivatives of the parent compound, 11-deoxocucurbitacin I.The structures of 23,24-dihydro-11-deoxocucurbitacin I and the glycosides, spinosides A and B were elucidated on the basis of extensive analysis of their high field 1H NMR, 13C NMR, high resolution mass spectra (fast atom bombardment, field desorption, chemical ionization, electron impact) and chemical interconversions.Spinosides A and B were cytotoxic in the KB cell culture assay.

Cleavage of 2-Phenyl-1,3-dioxolanes and Benzyl Ethers by Catalytic Transfer Hydrogenation

The selective deprotection of 2-phenyl-1,3-dioxolane derivatives and benzyl ethers of carbohydrates can be accomplished by catalytic transfer hydrogenation using hydrazine hydrate as hydrogen donor and 10percent palladium on carbon as catalyst.Under these conditions, 2-phenyl-1,3-dioxan and 2-alkyl substituted 1,3-dioxolane moieties remain unaffected.The proposed method is effective and the deprotected compounds are obtained in high yields.

New lignan glycosides with potent antiinflammatory effect, isolated from Justicia ciliata

Two new lignan glycosides, 4-O-[α-L-arabinopyranosyl-(1'''→2'')-β-D-xylopyranosyl-(1'''→5'')-β-D-ap iofuranosyl] diphyllin (1), named ciliatoside A (1), and 4-O-{[β-D-apiofuranosyl-(1''''→3''')-α-L-arabinopyranosyl-(1''''→2'')] [β-D-xylopyranosyl-(1''''→5'')]-β-D-apiofuranosyl}diphyllin (2), named ciliatoside B (2), were isolated from the whole plant of Justicia ciliata. The structures of 1 and 2 were determined by spectral and chemical methods. Compounds 1 and 2 strongly inhibited the accumulation of NO2- in lipopolysaccharide-stimulated RAW 264.7 cells in a concentration-dependent manner with IC50 values of 27.1 ± 1.6 and 29.4 ± 1.4 μM, respectively.

Methyl glycosides via Fischer glycosylation: translation from batch microwave to continuous flow processing

Abstract: A continuous flow procedure for the synthesis of methyl glycosides (Fischer glycosylation) of various monosaccharides using a heterogenous catalyst has been developed. In-depth analysis of the isomeric composition was undertaken and high consistency with corresponding results observed under microwave heating was obtained. Even in cases where addition of water was needed to achieve homogeneity—a prerequisite for the flow experiments—no detrimental effect on the conversion was found. The scalability was demonstrated on a model case (mannose) and as part of the target-oriented synthesis of d-glycero-d-manno heptose, both performed on multigram scale.
