The total asymmetric synthesis of a novel hybrid lipid possessing a 2,3-diacylthreitol backbone, rather than a 1,2-diacylglycerol backbone, is described. The title compound, Pea-PIP2, possesses a phosphatidylethanolamine (PE) headgroup at the 1-position and a phosphatidylinositol 4,5- bisphosphate (PtdIns(4,5)P2) headgroup at the 4-position. Reporters (biotin, fluorophores, spin label) were covalently attached to the free amino group of the PE, such that these reporters were targeted to the lipid-water interface. The diacyl moieties allow incorporation of Pea-PIP2 into a lipid bilayer, while the PtdIns(4,5)P2 moiety in the aqueous layer was specifically recognized by PtdIns(4,5)P2-specific binding proteins.
