| Description |
Treatment of hypoxic tumors is complicated due to higher radio/chemo resistance resulting in the subsequently lower clinical outcome of the treatment. We propose to explore a new concept of self-assembled polymer radiosensitizers to overcome the problem low hypoxic tumor radiosensitivity. The proposed approach is based on restoration of radiosensitivity of hypoxic cancer tissue by actively hypoxia-targeted delivery of reactive oxygen species (ROS)-precursors as well as on selective decomposition of hydrogen peroxide in hypoxic tissue influencing the HIF-1 alpha system. The proposed concept utilizes hydrophilic biocompatible polymer-based carriers with hypoxia-targeting nitroaromatics systems. The doctoral thesis will be based on synthesis, chemical and/or physicochemical characterization and study of self-assembly properties of such multi-stimuli-responsive nanoparticles with external environment; the exact topic will take into account the student´s interests. The studied nanoparticles and injectable depot systems will be designed for diagnostics and personalized immunoradiotherapy and immunochemotherapy of cancer and autoimmune diseases. Optimized nanoparticles will be then provided to collaborating biological workplaces for in vivo testing. |
