Liposomes functionalized on their surface with carbohydrates (glycoliposomes) represent an optimal approach for targeting of drugs to diseased tissues in vivo, thanks to biocompatibility, low toxicity and easy manufacturing of these lipid nanoparticles. Here we report on the study of liposomes including a novel glycosylated amphiphile and on the comparison of their features with those of glycosylated analogues described previously. Further, the capability of the different glucosylated formulations to interact with three breast cancer cell lines was investigated. Our results show that the hydrophobic portion of the lipid bilayer strongly influences both the properties and the internalization of glycosylated liposomes.

A series of bis-quaternary ammonium salts was easily prepared by the reaction of a long-chain tert-alkylamine with epichlorohydrin, and their surface-active properties were measured. The prepared amphipathic compounds had good water solubility and showed characteristic surface-active properties, particularly, extremely excellent foaming ability and foam stability for some specific compounds, such as the compound with a dodecyl and a tetradecyl group as the lipophilic chains. Their critical micelle concentration, which decreased with increased alkyl chainlength, is two orders of magnitude lower compared with the conventional mono-quaternary ammonium salts. In comparison with surface-active properties of bis-quaternary ammonium salts, prepared from various organic dichlorides, there are little differences based on the kind of connecting group in the surface-active properties except for foaming.

A dearomatized PN3P?-nickel hydride complex has been prepared using an oxidative addition process. The first nickel-catalyzed hydrosilylation of CO2 to methanol has been achieved, with unprecedented turnover numbers. Selective methylation and formylation of amines with CO2 were demonstrated by such a PN3P?-nickel hydride complex, highlighting its versatile functions in CO2 reduction.

experimental part, p. 911 - 923 (2010/09/04)
Here we describe uridine functionalization in the 5' position, which provides new classes of cationic and nonionic amphiphiles specifically designed as DNA transfection agents. The synthetic procedures developed to obtain the cationic uridine-head surfactants prevented intramolecular cyclization that occurs when uridine is functionalized in this position without using protecting groups in the uracil.
