Bi- to tetravalent glycoclusters presenting GlcNAc/GalNAc as inhibitors: from plant agglutinins to human macrophage galactose-type lectin (CD301) and galectins
Sabine André, Sabine; O'Sullivan, Shane; Koller, Christiane; Murphy, Paul V.; Gabius, Hans-Joachim (Royal Society of Chemistry, 2015-02-17)Emerging insights into the functional spectrum of tissue lectins leads to identification of new targets for the custom-made design of potent inhibitors, providing a challenge for synthetic chemistry. The affinity and ... -
Combining glycocluster synthesis with protein engineering: an approach to probe into the significance of linker length in a tandem-repeat-type lectin (galectin-4)
Andre, Sabine; Wang, Guan-Nan; Gabius, Hans-Joachim; Murphy, Paul V. (Elsevier, 2014-05-07)Complementarity in lectin-glycan interactions in situ is assumed to involve spatial features in both the lectin and the glycan, giving a functional meaning to structural aspects of the lectin beyond its carbohydrate-binding ... -
Glycoclusters as lectin inhibitors: comparative analysis on two plant agglutinins with different folding as a step towards rules for selectivity
O'Sullivan, Shane; Murphy, Paul V.; Gabius, Hans-Joachim; Sabine, Sabine (Elsevier, 2015-09-23)The emerging physiological significance of carbohydrate (glycan) protein (lectin) recognition engenders the interest to design synthetic inhibitors with a high level of selectivity among natural sugar receptors. Plant ... -
Influence of protein (human galectin-3) design on aspects of lectin activity
Caballero, Gabriel Garcia; Beckwith, Donella; Shilova, Nadezhda, V.; Gabba, Adele; Kutzner, Tanja J.; Ludwig, Anna-Kristin; Manning, Joachim C.; Kaltner, Herbert; Sinowatz, Fred; Cudic, Mare; Bovin, Nicolai, V.; Murphy, Paul V.; Gabius, Hans-Joachim (Springer, 2020-04-25)The concept of biomedical significance of the functional pairing between tissue lectins and their glycoconjugate counterreceptors has reached the mainstream of research on the flow of biological information. A major challenge ... -
Merging carbohydrate chemistry with lectin histochemistry to study inhibition of lectin binding by glycoclusters in the natural tissue context
André, Sabine; Kaltner, Herbert; Kayser, Klaus; Murphy, Paul V.; Gabius, Hans-Joachim (Springer, 2015-11-09)Recognition of glycans by lectins leads to cell adhesion and growth regulation. The specificity and selectivity of this process are determined by carbohydrate structure (sequence and shape) and topology of its presentation. ... -
Probing sulfatide-tissue lectin recognition with functionalized glycodendrimersomes
Murphy, Paul V.; Romero, Antonio; Xiao, Qi; Ludwig, Anna-Kristin; Jogula, Srinivas; Shilova, Nadezhda V.; Singh, Tanuja; Gabba, Adele; Javed, Bilal; Zhang, Dapeng; Medrano, Francisco J.; Kaltner, Herbert; Kopitz, Jürgen; Bovin, Nicolai V.; Wu, Albert M.; Klein, Michael L.; Percec, Virgil; Gabius, Hans-Joachim (Cell Press, 2021-01-22)The small 3-O-sulfated galactose head group of sulfatides, an abundant glycosphingolipid class, poses the (sphinx-like) riddle on involvement of glycan bridging by tissue lectins (sugar code). First, synthesis of head group ... -
Revealing biomedically relevant cell and lectin type-dependent structure–activity profiles for glycoclusters by using tissue sections as an assay platform
Kaltner, Herbert; Manning, Joachim C.; García Caballero, Gabriel; Di Salvo, Claudia; Gabba, Adele; Romero-Hernández, Laura L.; Knospe, Clemens; Wu, Dan; Daly, Harrison C.; O'Shea, Donal F.; Gabius, Hans-Joachim; Murphy, Paul V. (Royal Society of Chemistry, 2018-08-14)The increasing realization of the involvement of lectin-glycan recognition in (patho)physiological processes inspires envisioning therapeutic intervention by high-avidity/specificity blocking reagents. Synthetic glycoclusters ... -
Teaming up synthetic chemistry and histochemistry for activity screening in galectin-directed inhibitor design
Roy, René; Cao, Yihong; Kaltner, Herbert; Kottari, Naresh; Shiao, Tze Chieh; Belkhadem, Karima; André, Sabine; Manning, Joachim C.; Murphy, Paul V.; Gabius, Hans-Joachim (Springer, 2016-06-24)A hallmark of endogenous lectins is their ability to select a few distinct glycoconjugates as counterreceptors for functional pairing from the natural abundance of cellular glycoproteins and glycolipids. As a consequence, ...
