Projektbeschreibung
Wirkstoffsuche in Tumorsphäroiden
Die Entwicklung von Arzneimitteln zur Krebsbehandlung muss der dreidimensionalen und hypoxischen Natur von Tumoren Rechnung tragen. Das im Rahmen der Marie-Skłodowska-Curie-Maßnahmen finanzierte Projekt ImageTumor wird mithilfe von Tumorzell-Sphäroiden die Bedingungen des parentalen Tumors nachbilden und die Wirksamkeit und Permeabilität der Arzneimittelkandidaten testen. Die Arbeit wird sich auf metallbasierte antitumorale Verbindungen konzentrieren und ihre zelluläre Lokalisation mittels Röntgenfluoreszenz-Bildgebung untersuchen. Die Wechselwirkung mit verschiedenen Proteinen wird ebenfalls erforscht. Die Ergebnisse werden den Weg für einen repräsentativeren Prozess für die Wirkstoffsuche ebnen, der zur Entwicklung von marktreifen Krebsbehandlungen der nächsten Generation beitragen kann.
Ziel
According to estimates from the World Health Organization (WHO) in 2019, cancer is the second leading cause of death after heart failure before the age of 70. The field of metal-based anticancer drugs has been on the rise ever since the discovery of the anticancer properties of cisplatin in 1965, which is in daily clinical use against various types of cancer. Many compounds failed to enter clinical studies since their anti cancer activity is mainly studied in two dimensional (2D) monolayer cells which does not mimic the complex tumor micro environment in humans. In the human body the cancer tumors grow in 3-dimensional structure, hence it is vital to study the anticancer activity of a drug molecules in the 3D tumors rather in 2D mono layer cells. Next, tumor hypoxia (1% Oxygen), a situation where tumor cells are deprived of oxygen, is a major challenge for oncology. In this project we propose the synthesis of N-Heterocyclic Carbene/1,8-naphthalicanhydride conjugated series of metal complexes (Gold, Rhodium, Iridium) to study the anticancer activity and penetration depths in 3D tumor spheroids under hypoxia. We also investigate the activation by reduction mechanism in presence of cellular thiols and cytotoxicity in vitro (3D cell spheroids) and compare the results among the three metal centers. The metal protein interactions play key role in many biological processes; hence we also investigate the metal-protein interaction studies using capillary electrophoresis inductively-coupled mass spectrometry (at secondment). We will investigate the structure activity relationship between metals and of related coordinating ligands in 3D spheroid under hypoxic conditions. We mainly utilize X-Ray Fluorescence (XRF) imaging and synchrotron radiation to test the cellular localizations and penetration depth for the proposed metal complexes. This project is expected to yield unique insights towards optimization of next-generation anti-tumor drugs.
