Inositol phosphates play a fundamental role in many intracellular processes. Of particular importance is the role of phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P3] in the protein kinase B (PKB/Akt) signalling pathway. PtdIns(3,4,5)P3 recruits PKB to the cell membrane through binding interactions with its pleckstrin homology (PH) domain. In several human cancers, this signalling pathway is upregulated, resulting in increased cell growth and proliferation. In order to investigate the therapeutic potential of the PtdIns(3,4,5)P3–PH domain binding interaction, it is necessary to develop inositol phosphate-based probes. This DPhil dissertation highlights the synthesis of a number of derivatives of the PtdIns(3,4,5)P3 head group – inositol 1,3,4,5-tetrakisphosphate [Ins(1,3,4,5)P4]. These derivatives incorporated phosphate isosteres at both the 3- and 5-positions of Ins(1,3,4,5)P4, through the utilisation of novel protection and deprotection strategies. In addition, this dissertation highlights the efficient synthesis of the natural product inositol 1,3-bisphosphate [Ins(1,3)P2] and our work towards the synthesis of inositol pyrophosphate derivatives.
