  • Synthesis and evaluation of iminocoumaryl and coumaryl derivatized glycosides as galectin antagonists
    作者:Vishal Kumar Rajput、Hakon Leffler、Ulf J. Nilsson、Balaram Mukhopadhyay
    DOI:10.1016/j.bmcl.2014.05.063
    日期:2014.8
    A collection of iminocoumarylmethyl glycoside derivatives have been prepared by copper-catalyzed multi-component reaction of carbohydrate propargyl derivatives, sulfonyl azides, and salicylaldehyde or o-hydroxy acetophenone. The method is simple, versatile to all three components, and exceptionally high yielding. The carbohydrate N-sulfonyl iminocoumarine hybrid molecules were evaluated for binding galectin-1, -2, -3, -4 N, -4C, -7, -8 N, -9 N, and 9C using a competitive fluorescence polarization assay. Selective compounds were identified against galectin-3, 7, 8 N, and 9 N with up to 40-fold affinity enhancements relative to methyl alpha-D-galactopyranoside due to the coumarylmethyl moieties.

  • Synthetic 1,2,3-triazole-linked glycoconjugates bind with high affinity to human galectin-3
    作者:Marcelo Fiori Marchiori、Dênio Emanuel Pires Souto、Leandro Oliveira Bortot、João Francisco Pereira、Lauro Tatsuo Kubota、Richard D. Cummings、Marcelo Dias-Baruffi、Ivone Carvalho、Vanessa Leiria Campo

    This work describes the synthesis of the 1,2,3-triazole amino acid-derived-3-O-galactosides 1-6 and the 1,2,3-triazole di-lactose-derived glycoconjugate 7 as potential galectin-3 inhibitors. The target compounds were synthesized by Cu(I)-catalyzed azide-alkyne cycloaddition reaction ('click chemistry') between the azido-derived amino acids N-3-ThrOBn, N-3-PheOBn, N-3-N-Boc-TrpOBn, N-3-N-Boc-LysOBn, N-3-O-tBu-AspOBn and N-3-L-TyrOH, and the corresponding alkyne-based sugar 3-O-propynyl-GalOMe, as well as by click chemistry reaction between the azido-lactose and 2-propynyl lactose. Surface plasmon resonance (SPR) assays showed that all synthetic glycoconjugates 1-7 bound to galectin-3 with high affinity, but the highest binders were the amino acids-derived glycoconjugates 2 (K-D 7.96 mu M) and 4 (KD 4.56 mu M), and the divalent lactoside 7 (K-D1 0.15 mu M/K-D2 19 mu M). Molecular modeling results were in agreement with SPR assays, since more stable interactions with galectin-3 were identified for glycoconjugates 2, 4 and 7. Regarding compounds 2 and 4, they established specific cation-pi (Arg144) and ionic (Asp148) interactions, whereas glycoconjugate 7 was capable to bridge two independent galectin-3 CRDs, creating a non-covalent cross-link between two monomers and, thus, reaching a submicromolar affinity towards galectin-3.
