Synthesis of: N -acetylglucosamine and N -acetylallosamine resorcinarene-based multivalent β-thio-glycoclusters: Unexpected affinity of N -acetylallosamine ligands towards Wheat Germ Agglutinin
(Royal Society of Chemistry, 2020-09)
Herein, we report the synthesis of calix[4]resorcinarene-based multivalent ligands bearing β-S-GlcNAc and β-S-AllNAc recognition elements. A clickable β-S-AllNAc derivative was successfully prepared from a β-thioalkynyl ...
Clinanthus microstephium, an Amaryllidaceae species with Cholinesterase Inhibitor Alkaloids: Structure−Activity analysis of Haemanthamine skeleton derivatives
(Wiley VCH Verlag, 2019-05)
Plants of the Amaryllidaceae family are well-known (not only) for their ornamental value but also for the alkaloids that they produce. In this report, the first phytochemical study of Clinanthus genus was carried out. The ...
Structural basis for ligand recognition in a mushroom lectin: Solvent structure as specificity predictor
(Elsevier, 2011-05)
Lectins are able to recognize specific carbohydrate structures through their carbohydrate recognition domain (CRD). The lectin from the mushroom Agaricus bisporus (ABL) has the remarkable ability of selectively recognizing ...
Chlorogenic acid, anthocyanin and flavan-3-ol biosynthesis in flesh and skin of Andean potato tubers (Solanum tuberosum subsp. andigena)
(Elsevier, 2017-08-15)
Natural variation of Andean potato was used to study the biosynthesis of phenolic compounds. Levels of phenolic compounds and corresponding structural gene transcripts were examined in flesh and skin of tubers. Phenolic ...

The elaborate route for UDP-arabinose delivery into the Golgi of plants
(National Academy of Sciences, 2017-04)
In plants, L-Arabinose (Ara) is a key component of cell wall polymers, glycoproteins, as well as flavonoids, and signaling peptides. Whereas the majority of Ara found in plant glycans occurs as a furanose ring (Araf), the ...
