Phosphatidylglycerophosphate methyl ester (PGP-Me), a major constituent of the archaeal purple membrane, is essential for the proper proton-pump activity of bacteriorhodopsin (bR).
A novel 48-membered cyclic lipid, in which two ether and two amide groups serve as a linker between its hydrophilic and hydrophobic moiety, was synthesized starting from d-1,2-O-isopropylidene-sn-glycerol. The synthetic scheme is featured by the selective removal of protecting groups, followed by the introduction of mesylate and carboxylic acid, which sequentially leads to the formation of ether and amide bonds, respectively. Transmission electron microscopic observation confirmed that this lipid forms submicrosized helical ribbons.
Abstract An efficient method of synthesizing fluorine-containinganalogues of 1-lysoglycerophospholipids (1-LPLs) by introducing a palmitoyl moiety starting from bis(2,2,2-trifluoroethyl)phosphonoacetate (Still–Gennari reagent) is described. The method effectively employs Horner–Wadsworth–Emmons reagents as masked 1-LPL derivatives to prepare a series of analogues of 1-lysophosphatidic acid (1-LPA), 1-l

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.
Chiral 48-membered antiparallel cyclobolaphiles and their diastereomer having two diacetylenes were convergently synthesized utilizing both cross-coupling method (CuI, pyrrolidine) and Glaser intramolecular cyclization, starting from commercially available d- and l-1,2-O-isopropylidene-sn-glycerol as chiral sources.
