  1. Synthesis of and molecular dynamics simulations on a tetrasaccharide corresponding to the repeating unit of the capsular polysaccharide from...
    Johan D M Olsson, Jens Landström, ... Göran Widmalm

    Org Biomol Chem 7(8):1612 (2009) PMID 19343247

    Syntheses of two oligosaccharides as methyl glycosides related to the repeating unit of S. enteritidis capsular polysaccharide (CPS) are presented. The trisaccharide corresponds to the backbone of the CPS whereas the tetrasaccharide is a model for the repeating unit which has a branched structure. M...
  2. Molecular specification and patterning of progenitor cells in the lateral and medial ganglionic eminences.
    Eric S ES Tucker, Samantha S Segall, ... Anthony-Samuel AS Lamantia

    J Neurosci 28(38):9504-18 (2008) PMID 18799682

    We characterized intrinsic and extrinsic specification of progenitors in the lateral and medial ganglionic eminences (LGE and MGE). We identified seven genes whose expression is enriched or restricted in either the LGE [biregional cell adhesion molecule-related/downregulated by oncogenes binding pro...
  3. DFT and NMR studies of 2JCOH, 3JHCOH, and 3JCCOH spin-couplings in saccharides: C-O torsional bias and H-bonding in aqueous solution.
    Hongqiu Zhao, Qingfeng Pan, ... Anthony S Serianni

    J Org Chem 72(19):7071-82 (2007) PMID 17316047

    These results suggest that H-bonding between adjacent and/or remote residues may play a role in dictating preferred glycosidic bond conformation in simple and complex oligosaccharides in aqueous solution....
  4. Conformational analysis of methyl 5-O-methyl septanosides: effect of glycosylation on conformer populations
    Matthew P MP DeMatteo, Song S Mei, ... Mark W MW Peczuh

    Carbohydr Res 341(18):19 (2006) PMID 17056019

    We report the synthesis of 3 and 4 and describe their preferred solution conformations through a combination of ab initio/DFT calculations and (1)H (3)J(H,H) NMR coupling constant analysis. The conformations of 3 and 4 observed in this study are discussed in comparison to those of the parent (C5 hyd...
  5. Synthesis of a di- and a trisaccharide related to the O-antigen of Escherichia coli O83:K24:H31
    Geetanjali G Agnihotri and Anup Kumar AK Misra

    Carbohydr Res 341(14):6 (2006) PMID 16884704

    Di- and trisaccharide fragments related to the repeating unit of the O-antigen of Escherichia coli O83:K24:H31 have been synthesized as their methyl glycoside analogs starting from readily available monosaccharides.
  6. Alkylalanes and methyl furanosides: regioselective O-debenzylation or acetal cleavage
    Cai C Jia, Yongmin Y Zhang, ... Matthieu M Sollogoub

    Carbohydr Res 341(12):10 (2006) PMID 16730681

    Perbenzylated methyl pentofuranosides were submitted to the action of three alkylalanes and regioselective debenzylation at O-2 of the four pentoses was observed when choosing the right match between anomeric configuration and aluminium reagent. Diisobutylalane (DIBAL-H) allowed an easy access to re...
  7. Methyl 4-O-benzoyl-2,3-O-isopropylidene-alpha-L-rhamnopyranoside.
    K Hanna M KH Jonsson, Lars L Eriksson, and Göran G Widmalm

    Acta Crystallogr C 62(Pt 8):o447-9 (2006) PMID 16891715

  8. [Preliminary pharmaphylogenetic study on Ranunculaceae].
    Yong Y Peng, Si-bao SB Chen, ... Pei-gen PG Xiao

    Zhongguo Zhong Yao Za Zhi 31(13):1124-8 (2006) PMID 17048618

    OBJECTIVE: To deal with the correlation between phylogeny, chemical constituents and pharmaceutical aspects of Ranunculaceae, namely a pharmaphylogenic study of this taxon. METHOD: Based on chemical, pharmaceutical (both ethnopharmacologic and pharmacological) information, linking with different pla...
  9. Stereocontrolled synthesis of the D- and L-glycero-beta-D-manno-heptopyranosides and their 6-deoxy analogues. Synthesis of methyl alpha-l-rh...
    David D Crich and Abhisek A Banerjee

    J Am Chem Soc 128(24):8078-86 (2006) PMID 16771524 PMCID 2617734

    The synthesis of d- and l-glycero-alpha-manno-thioheptopyranosides, protected with 4,6-O-alkylidene-type acetals is described. In glycosylations carried out with preactivation with the 1-benzenesulfinylpiperidine/trifluoromethanesulfonic anhydride couple, both the D- and L-glycero series exhibit exc...

  10. Methyl 4-O-beta-L-galactopyranosyl-beta-D-glucopyranoside (methyl beta-L-lactoside).
    Qingfeng Q Pan, Bruce C BC Noll, and Anthony S AS Serianni

    Acta Crystallogr C 62(Pt 2):o82-5 (2006) PMID 16456293

    Methyl beta-L-lactoside, C13H24O11, (II), is described by glycosidic torsion angles phi (O5Gal-C1Gal-O4Glc-C4Glc) and psi (C1Gal-O1Gal-C4Glc-C5Glc) of 93.89 (13) and -127.43 (13) degrees , respectively, where the ring atom numbering conforms to the convention in which C1 is the anomeric C atom and C...
