Neue Wirkstoffklasse zur reversiblen Blockierung des Proteasoms

Wissenschaftler entdecken neuen Ansatzpunkt für Krebstherapie

(PresseBox) (München, )
Als "Recyclinghof" der Zelle steuert das Proteasom lebenswichtige Funktionen. Wird es blockiert, erstickt die Zelle am eigenen Müll. Vor allem Krebszellen reagieren empfindlich, denn sie benötigen das Proteasom für ihr unkontrolliertes Wachstum. Nun charakterisierten Biochemiker der Technischen Universität München (TUM) die Grundstruktur einer neuen Wirkstoffklasse, die das Proteasom in besonderer Weise angreift. Auf der Grundlage dieses bislang unbekannten Bindungsmechanismus könnten neue Medikamente entwickelt werden. Über ihre Ergebnisse berichten die Forscher in der Fachzeitschrift "Angewandte Chemie".

Das Proteasom, ein großer Eiweißkomplex, erfüllt in den Zellen des Körpers eine lebenswichtige Aufgabe: Ähnlich einer Recyclinganlage zerlegt es nicht mehr benötigte Proteine in kurze Iwvnlo yom mvbai sjh eehsd Skhmcmbymaxjuuyi.
