Abstract
Trypanosomatiden sind einzellige Parasiten, die beim Menschen schwere Erkrankungen verursachen. Ein vielversprechender Angriffspunkt für potenzielle Arzneistoffe ist das Tryparedoxin, ein essenzielles Redoxprotein, das bei der Inaktivierung von Hydroperoxiden in den Zellen der Parasiten eine wichtige Rolle spielt. Das Thienopyrimidinon-Derivat CFT, ein irreversibler Inhibitor, bindet kovalent an Tryparedoxin und vernetzt es zum Dimer, das durch mehrere Wechselwirkungen zwischen Inhibitor-Protein, Inhibitor-Inhibitor und Protein-Protein stabilisiert wird. Die strukturellen Grundlagen dieser Interaktionen könnten für die Entwicklung wirksamerer Inhibitoren gegen Tryparedoxin hilfreich sein.
Trypanosomatides are single-celled parasites that cause serious diseases such as sleeping sickness and chagas disease in humans. A promising point of attack for potential drugs is tryparedoxin, an essential redox protein that plays an important role in the inactivation of hydroperoxides in the cells of the parasites. The thienopyrimidinone derivative CFT, an irreversible inhibitor, binds covalently to tryparedoxin and links it to the dimer, which is stabilized by several interactions between inhibitor protein, inhibitor inhibitor and protein protein. The structural basis of these interactions could be helpful for the development of more effective inhibitors against tryparedoxin.
