Abstract
A series of glycolipids have been prepared which contain a cluster galactoside moiety with high affinity for the hepatic asialoglycoprotein receptor and a bile acid ester moiety which mediates stable incorporation into liposomes. Loading of liposomes with these glycolipids at a ratio of 5% (w/w) resulted in efficient recognition and uptake of the liposomes by the liver. Preinjection with asialofetuin almost completely inhibited the uptake, establishing that the liposomes were selectively recognized and processed by the asialoglycoprotein receptor on liver parenchymal cells. In contrast, a glycolipid content of 50% (w/w) led to a liver uptake that could not be inhibited by preinjection with asialofetuin, indicating that the liposomes were now processed by the Gal/Fuc-recognizing receptor on liver macrophages. The results presented in this study are important for future targeting of water-soluble and amphiphilic drugs, enveloped in these glycolipid-laden liposomes, to parenchymal liver cells.

Abstract
The binding affinity of synthetic bi- and triantennary galactose ligands (Kichler, A. and Schuber, F. (1995) Glycoconj. Chem., 12, 275 281) has been determined for the Gal/GalNAc receptors of rat hepatocytes and macrophages. The highest affinities were observed with the triantennary structures, in agreement with the clustering effect known to occur with more complex oligosaccharide structures. However, these ligands present very similar affinities for the receptors of both cell types and thus lack the necessary selectivity for specific hepatocyte targeting.

Abstract
Phospholipid conjugates of mono- and disaccharides tethered with an n-decanyl spacer were efficiently synthesized via an improved reductive amination of deprotected omega-oxodecanyl beta-glycosides and phosphatidylethanolamines with or without alkenyl groups. The omega-oxodecanyl beta-glycosides were prepared by stereoselective glycosidation of glycosyl halides with 1, 10-decanediol followed by pyridinium dichromate oxidation. The acetyl groups of the omega-oxodecanyl beta-glycosides were removed with sodium methoxide prior to their conjugation with phosphatidylethanolamines.

Abstract
An efficient synthesis of neoglycophospholipids with variable length alkyl spacer chains is described. Neoglycophospholipids tethered by alkyl chains of 3, 5, 7, 10, and 16 methylene units were synthesized in good overall yields in four steps. The key intermediates, omega-oxoalkyl glycopyranosides, were synthesized in two steps by glycosidation of chloro (or ethylthio) glycosides with a diol followed by oxidation of the remaining hydroxy group to an aldehyde functionality. Conjugation of the omega-glycoalkyl aldehyde with distearoylphosphatidylethanolamine via an improved reductive amination procedure significantly enhanced efficiency and yields with respect to those from traditional procedures. The amphiphilic properties of the neoglycophospholipids were characterized at the air-water interface. While the carbohydrate head group had relatively little effect, the length of the alkyl spacer profoundly influenced surface area-pressure isotherms.

Abstract
We have synthesized bi- and tri-antennary galactose ligands by coupling 1-thio-beta-D-galactose derivatives to the alpha- and epsilon-amino groups of L-lysine and L-lysyl-L-lysine via highly flexible hydrophilic spacer arms that allow variation of their intergalactose distances. The interaction of these ligands with the Gal/GalNAc receptor of HepG2 cells showed a binding affinity that was: (i) in agreement with the clustering effect known to occur with more complex oligomeric structures, i.e. tri- > bi-antennary; ii) dependent on the intergalactose distances (optimal interactions were observed for the tri-antennary structures with distances > 2 nm). These ligands, that can be easily conjugated to bioactive (macro) molecule carrier systems, could be useful for their targeting to hepatocytes.

Abstract
Optimal in vitro gene delivery with cationic lipids requires an excess of cationic charges with respect to DNA phosphates. In these conditions, in vivo delivery will be hampered by interference from cationic lipid-binding macromolecules either circulating or in the extracellular matrix. To overcome this problem, we are developing a modular transfection system based on lipid-coated DNA particles reminiscent of enveloped viruses. The particle core consists of the lipopolyamine-condensed nucleic acid in an electrically neutral ratio to which other synthetic lipids with key viral properties are hydrophobically adsorbed. As a first result, we have found that a good transfection level can be achieved simply with the neutral core particle, provided a zwitterionic lipid (dioleoyl phosphatidylethanolamine) is added to completely coat the DNA. Addition of lipids bearing a fusogenic or a nuclear localization peptide head group to the particles does not significantly improve an already efficient system, in contrast to polylysine-based gene transfer methods that rely on lysosomotropic or fusogenic agents to be effective. This emphasizes the distinctive properties of the lipopolyamines, including cell membrane destabilization, endosome buffering capacity, and possibly nuclear tropism. Most importantly, addition of lipids with a triantennary galactosyl residue drives the neutral nucleolipidic particles to the asialoglycoprotein receptor of human hepatoma HepG2 cells: Transfection increases approximately 1000-fold with 25% galactolipid. This receptor-mediated process is saturable and slightly less efficient than receptor-independent transfection obtained in vitro with a large excess of cationic lipid alone. Yet, electrically silent particles may provide an attractive solution for gene transfer in vivo where their external saccharide coat should allow them to diffuse within the organism and reach their target cells.

Abstract
Vesicles are being investigated as drug carriers, especially for enhancing the therapeutic effectiveness of the drug while minimizing its side effects. Drug targeting can be achieved if there is a specific recognition of the vesicle's outer wall by specific cells. With these objectives in mind new glycolipids fitted with fluorinated, hydrogenated or mixed, single and double-tails, containing either a gluco- or a galactopyranose residue in their hydrophilic head, were synthesized and their ability to achieve self-organized supramolecular systems was assessed. Replacement of hydrogen by fluorine in these glycolipids was found to enhance biological tolerance. Thus, a fluorinated single-tailed glycolipid displayed no action on red blood cells at concentrations as high as 50 g/l while its hydrogenated analog was hemolytic at 5 g/l. 100% of survival was obtained one month after intravenous or intraperitoneal injection into mice of isotonic dispersions of single and double-tailed glycolipids at a dose of 500 mg/kg. These glycolipids were innocuous on Namalva cell cultures at a concentration of 0.1 g/l.

Abstract
We have assessed the potential of reconstituted Sendai viral envelopes containing only the fusion protein (F-virosomes) as biological carriers for the delivery of drugs and macromolecules. [125I]lysozyme entrapped in F-virosome is used to study its distribution in various organs of Balb/c mouse in vivo as a function of dose and time. F-virosomes injected intravenously are rapidly cleared from circulation. A major percentage (55-60%) of vesicle contents is delivered to liver at 15 min after injection, showing thereby the liver to be the major site for the accumulation of vesicles. Uptake of virosomes by liver is found to reach a near saturation level at a dose of 0.5 mg F-protein associated with virosomes. In competition studies, the inhibitory effect of asialofetuin on the uptake of F-virosomes suggests the involvement of asialoglycoprotein receptor in its recognition by hepatic parenchymal cells. Incorporation of asialoganglioside-GM1 in the F-virosomes enhanced the uptake by about 1.6-fold. The observed specific interaction of hepatic receptor with F-protein containing a terminal galactose moiety is further supported by degalactosylation of F-virosomes with hard-shelled clam exoglycosidase. The uptake of degalactosylated F-virosomes by liver is found to be significantly reduced. The subcellular radioactivity profile in liver cells exhibits a considerable decrease in cytosolic localisation of the degalactosylated F-virosomal contents with a concomitant increase in their accumulation in lysosomal/mitochondrial fraction as compared to the untreated virosomes. Trypsinized and heat-treated F-virosomes also reflect similar subcellular distribution profile as that of degalactosylated virosomes. Moreover, F-virosomes are able to interact and deliver [125I]lysozyme to the HepG2 cells in culture in the presence of a potent inhibitor of endocytotic process. These results indicate the involvement of specific binding of F-proteins with hepatic receptors followed by their fusion with the membrane of liver cells in the delivery of [125I]lysozyme. The findings reported here open up the possibility of using F-virosomes with defined specificity as fusogenic vehicles for efficient delivery of drugs and biologically active macromolecules both in vivo and in vitro.

Abstract
Many recent reports have demonstrated that rapid uptake of liposomes in vivo by cells of the mononuclear phagocytic system (MPS), which has restricted their therapeutic utility, can be overcome by incorporation of lipids derivatized with the hydrophilic polymer polyethylene glycol (PEG). The structure-function relationship of PEG-derivatized phosphatidylethanolamine (PEG-PE) has been examined by measurement of blood lifetime and tissue distribution in both mice and rats. The results are reviewed and contrasted with those from liposomes without PEG-PE or other surface modifications. With a PEG molecular weight in the range of 1000 to 5000, prolonged circulation and reduced MPS uptake is achieved. After 24 h, up to 35% of the injected dose remains in the blood and less than 10% is taken up by the two major organs of the MPS, liver and spleen, compared with 1% and up to 50%, respectively, for liposomes without PEG-PE. Other important advantages of PEG-PE have been identified: prolonged circulation is independent of liposome cholesterol content, degree of hydrocarbon chain saturation in either the PC or the PE lipid anchor, lipid dose, or addition of most other negatively charged lipids. This versatility in lipid composition and dose is important for controlling drug release in a liposome-based therapeutic agent. Steric stabilization has been proposed as a theoretical basis for the results and some initial results testing this hypothesis have been reported. A description of a theoretical model is presented here and evaluated with the data available. The results are compared with other particulate drug carriers and the range of potential applications are considered.
