Phospholipid synthesis using tetrahydropyranyl glycerol was investigated to produce chiral diglycerides, phosphorylated, and target phospholipid compounds. The synthetic compounds were used for the establishment of structure activity relationships with respect to phospholipid-phospholipid and phospholipid-protein interactions. The synthesis involves regioselective incorporation of three different substituents at the three glycerol positions that normally requires the use of multiple protecting groups. An efficient general route to phosphatidylcholine and phosphatidic acid is applicable to the preparation of a wide range of structurally related glycerophospholipid derivatives. The investigation resulted a facile and efficient method for the preparation of a wide range of diacylglycerols and phospholipids, including phospholipid acid, symmetric and mixed chain phosphatidylcholines.

Synthetic phosphatidylinositol phosphate (PtdInsPn) derivatives play a pivotal role in broadening our understanding of PtdInsPnmetabolism. However, the development of such tools is reliant on efficient enantioselective and regioselective synthetic strategies. Here we report the development of a divergent synthetic route applicable to the synthesis of deuterated PtdIns4Pand PtdIns5Pderivatives. The synthetic strategy developed involves a key enzymatic desymmetrisation step using Lipozyme TL-IM. In addition, we optimised the large-scale synthesis of deuteratedmyo-inositol, allowing for the preparation of a series of saturated and unsaturated deuterated PtdIns4Pand PtdIns5Pderivatives. Experiments in MCF7 cells demonstrated that these deuterated probes enable quantification of the corresponding endogenous phospholipids in a cellular setting. Overall, these deuterated probes will be powerful tools to help improve our understanding of the role played by PtdInsPnin physiology and disease.

Ac1PIM1is a potential biosynthetic intermediate for phosphatidylinositol mannosides (PIMs) fromMycobacterium tuberculosis. We achieved the first synthesis of Ac1PIM1by utilizing an allyl-type protecting group strategy and regioselective phosphorylation of inositol. A very potent agonist of an innate immune receptor DCAR, which is better than previously known agonists, is demonstrated.

The stereospecific structure of triacylglycerols (TAGs) affects the bioavailability of fatty acids. Lack of enantiopure reference compounds and effective enantiospecific methods have hindered the stereospecific analysis of individual TAGs. Twelve novel enantiostructured AAB-type TAGs were synthesized containing one of the three n-3 polyunsaturated fatty acid: α-linolenic acid (ALA), eicosapentaenoic acid (EPA), or docosahexaenoic acid (DHA) in sn-1 or sn-3 position. These compounds formed six enantiomer pairs, which were separated with recycling high-performance liquid chromatography using chiral columns and UV detection. The chromatographic retention behavior of the enantiomers and the stereospecific elution order were studied. The enantiomer with an n-3 PUFA in the sn-1 position eluted faster than the enantiomer with the n-3 PUFA in the sn-3 position, regardless of the carbon chain length and number of double bonds of the PUFA. TAG enantiomers containing DHA exhibited highly different retention on the chiral column and were separated after the first column, whereas recycling was needed to separate the enantiomer pairs containing ALA or EPA. The system using two identical columns and one mobile phase, without sample derivatization, proved to be very effective also for peak purity assessment, confirming the enantiopurity of the synthesized structured TAGs being higher than 98 percent (96 percent ee).
