Vesicles and other supramolecular systems made from double-tailed synthetic glycolipids derived from galactosylated tris(hydroxymethyl)aminomethane
摘要:
A series of double-tailed hydrocarbon glycolipids derived from tris(hydroxymethyl)aminomethane (Tris) have been prepared. These amphiphiles consist of three parts: a hydrophilic head derived from mono- or polygalactosylated Tris, a linking arm of peptidic nature and a hydrophobic double tail composed of 12 or 18 carbon atom chains. The ability of the new glycolipids to disperse in water, the morphology of the self-assemblies they form and the stability of the latter were shown to depend largely on the volumetric ratio between hydrophilic head and hydrophobic tails. Comparative studies of such substrates allowed a better understanding of the relative role of the various parameters that govern the formation of tubular systems relative to vesicular organizations. In all cases, the introduction of oligomeric galactosylated heads favoured stable vesicular systems over tubules.
