Even though many potent chemotherapeutic agents are now available, their delivery to the site of action within the tumor is hampered by a host of barriers. Thus, design of strategies for safe and effective delivery of drugs to brain tumors remains an ongoing challenge of chemotherapy. The aim of this project is to design a novel multi-component platform for selective delivery of drugs into brain tumor cells. The system is based on a clinically used MRI contrast agent MION (magnetic iron oxide nanoparticles) and combines targeting and prodrug features with MRI observability. The accumulation of the inactive system at the tumor site is induced by ''magnetic targeting'' approach and monitored by non-invasive MR imaging. Once the system reaches the target site, it is activated by an externally applied trigger. The platform is not limited to delivery of small hydrophobic drugs and can also be applied to deliver hydrophilic macromolecules, insusc! eptible to the mechanisms of multidrug resistance. If proves feasible, the proposed system could offer the effective, selective, safe and yet minimally invasive treatment for brain tumors.
