1. Tumor Cell Targeting of Stabilized Liposome Conjugates : Experimental studies using boronated DNA-binding agents
Sammanfattning : To further develop cancer therapy, targeted delivery of cell killing agents directly to tumor cells is an interesting approach. This thesis describes the development of PEG-stabilized liposome conjugates targeting either epidermal growth factor receptor (EGFR) using its natural ligand EGF, or human epidermal growth factor receptor 2 (HER-2) using the antibody trastuzumab. LÄS MER
2. EGFR- and HER2-Binding Affibody Molecules : Cellular studies of monomeric, dimeric and bispecific ligands
Sammanfattning : Abnormal expression and signaling of the ErbB receptors is associated with the development and progression of several forms of cancer. In this thesis, new ErbB-targeting affibody molecules are evaluated regarding their cellular effects in vitro. LÄS MER
3. Two-Step Targeting for Effective Radionuclide Therapy : Preclinical Evaluation of 125I-labelled Anthracycline Delivered by Tumour Targeting Liposomes
Sammanfattning : For the treatment of cancer, Auger-electron emitting radionuclides are strongly dependent on their close proximity to DNA to utilize the local therapeutic potential of the Auger electrons. This thesis investigates a two-step targeting approach that uses targeting liposomes for the delivery of an Auger-electron emitter, 125I, coupled to a DNA-binding compound, Comp1, to the tumour-cell DNA. LÄS MER
4. Indirect Radiohalogenation of Targeting Proteins : Labelling Chemistry and Biological Characterisation
Sammanfattning : In about half of all newly diagnosed cancer cases, conventional treatment is not adequately curative, mainly due to the failure of conventional techniques to find and kill residual cells and metastases, which might consist of only a few malignant cells, without causing unacceptable complications to healthy tissue. To solve the problem a more selective delivery of cytotoxic substances to tumour cells is needed. LÄS MER
Sammanfattning : Tumour targeted radiotherapy is an appealing approach for treatment of disseminated tumour cells. A targeting agent that specifically binds to a structure on tumour cells is then used to transport therapeutically relevant radionuclides. The epidermal growth factor receptor, EGFR, is overexpressed on tumour cells in several malignancies, e.g. LÄS MER
