This thesis is concerned with the synthesis, characterisation and evaluation of novel metal complexes for their application as anti-cancer agents. It contains the in vitro cell results, along with a range of other techniques to determine their biological relevance and their potential as anti-cancer agents.
Chapter 1 contains an introduction to the project including a literature search, previously synthesised complexes and project aims
Chapter 2 presents the synthesis and characterisation of novel β-diketonate and β-ketoiminate ligands. X-ray crystallographic data are analysed for some of the ligands.
Chapter 3 discusses the synthesis and characterisation of novel β-ketoiminate ruthenium chloride complexes. X-ray crystallographic data are analysed for all of the complexes.
Chapter 4 introduces the MTT technique for assessing cytotoxicity, and presents in vitro activities for the library of complexes synthesised in Chapter 3.
Chapter 5 looks at modifications of the previous ruthenium (II) complexes, introducing new ligands and iridum metal centres. X-ray crystallographic data for all of these complexes has been discussed, along with in vitro activity against a range of cell lines.
Chapter 6 introduces hypoxia and states the cytotoxicities of a range of complexes under 1.0% and 0.1% oxygen concentrations.
Chapter 7 discusses mechanistic studies on the complexes, including hydrolysis, hydrophobicity, Comet assay, apoptosis and thioredoxin reductase inhibition.
Chapter 8 introduces the previous group IV work within the group and an extension of the library by synthesis of β-ketoiminate titanium complexes. X-ray crystallographic analysis is discussed where applicable.
Chapter 9 contains experimental details and characterisation data for all compounds described in Chapters 2, 3, 5 and 8. Also protocols for all the biological studies.
Appendix presents a summary of X-ray crystallographic structure analysis for any crystals obtained within this wor
