The synthesis of the complete family of phosphatidylinositol phosphate analogues (PIPs) from five key core intermediates A-E is described. These core compounds were obtained from myo-inositol orthoformate 1 via regioselective DIBAL-H and trimethylaluminium-mediated cleavages and a resolution-protection process using camphor acetals 10. Coupling of cores A-E with phosphoramidites 34 and 38, derived from the requisite protected lipid side chains, afforded the fully-protected PIPs. Removal of the remaining protecting groups was achieved via hydrogenolysis using palladium black or palladium hydroxide on carbon in the presence of sodium bicarbonate to afford the complete family of dipalmitoyl- and amino-PIP analogues 42, 45, 50, 51, 58, 59, 67, 68, 76, 77, 82, 83, 92, 93, 99 and 100. Investigations using affinity probes incorporating these compounds have identified novel proteins involved in the PI3K intracellular signalling network and have allowed a comprehensive proteomic analysis of phosphoinositide interacting proteins.

Cardiolipin (1) is a dimeric phospholipid found in the mitochondrial membranes of both plants and animals. In order to understand better its role, we report the preparation of an immobilised analogue (2) using phosphoramidite chemistry; the probe has been used successfully to bind a recombinant protein containing a cardiolipin-binding domain.

The full synthesis of phosphatidic acid (PA) and phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2)-coupled beads was reported. They were used as affinity matrices to identify PA-interacting proteins. A number of known proteins were identifi

New PtdIns(3,4,5)P3 binding proteins have been identified utilising PtdIns(3,4,5)P3 modified affinity matrix 1 which was synthesised from myo-inositol derivative 2, phosphoramidite 9 and an agarose based solid support.
