Allosterische, Wirkstoff‐zugängliche Bindestellen in β‐Propeller‐Lektinen

Abstract: Lektine sind vielversprechende Zielproteine bei der Entdeckung von Wirkstoffen zur Bekämpfung antibiotikaresistenter Keime. Noch sind aber keine nicht‐kohlenhydratbasierten Therapeutika gegen diese Proteinklasse entwickelt worden. Hier präsentieren wir eine Wirkstoff‐zugängliche Bindestelle im β‐Propeller‐Lektin BambL aus Burkholderia ambifaria als mögliches Ziel für allosterische Wirkstoffentwicklung. Diese Bindestelle wurde durch 19F‐NMR‐basiertes Fragmentscreening und einen Computer‐gestützten Algorithmus z… Show more

“…Recent experimental data suggest existence of such druggable secondary sites, especially in mammalian C-type lectins and galectins. [124][125][126][127][128] Examples of allosteric inhibitors include 4-quinolones 129 as DC-SIGN inhibitors (e.g. 19), thiazolopyrimidines (e.g.…”

“…In contrast, coming from a fragmentbased screening approach, several sub-millimolar inhibitors of BambL have been recently identified. 548 BambL is a lectin of B. ambifaria, causing chronic infections. 501 Evidence from biophysical analysis and single point mutations introduced into the protein suggest an allosteric mode of action.…”

“…The use of 19 F-NMR-based experiments in fragment-based screening has been employed also in the search for druggable pockets in multimeric lectins, as in β-propeller lectins. 123 The hits identified by 19 F-NMR were further validated by orthogonal methods, such as SPR and TROSY NMR experiments. In that sense, the NMR approach identified druggable pockets in a bacterial b-propeller lectin, which could be used in the design of allosteric inhibitors.…”
