We report herein the synthesis of a novel family of cationic lipids, characterized by a trimethylammonium headgroup linked through a phosphate function to either two identical or two different lipid chains. The novelty of this study arises from the use of a trialkyl phosphate group to associate the hydrophobic domain to the cationic polar head. The structure of these new cationic lipids, which differs from that of previously reported lipophosphoramidates, is closer to the phospholipids encountered in the plasma membrane, and possesses a phosphocholine polar head. Evaluation of the transfection activity allowed us to compare the efficacy of cationic lipophosphates with that of lipophosphoramidates. These results demonstrate that cationic lipophosphates and lipophosphoramidates having otherwise identical chemical structures exhibit similar transfection efficacies. The second conclusion is that the structure of the lipid domain is a much more important parameter in governing transfection efficacy than the composition of the linker moiety. The best results were obtained with cationic lipophosphates or lipophosphoramidates possessing two different lipid chains, for example one oleyl chain with one phytanyl chain. These nonsymmetric cationic lipids exhibited transfection efficacies that were 10-to 200-fold better than those obtained with Lipofectamine used as a commercial standard.

Twelve derivatives of hexadecylphosphocholine (miltefosine) were synthesized to determine how the position and length of the alkyl chain within the molecule influence their biological activities. The prepared alkylphosphocholines have the same molecular formula as miltefosine. Activity of the compounds was studied against a spectrum of tumour cells, two species of protozoans, bacteria and yeast. Antitumour efficacy of some alkylphosphocholines measured up on MCF-7, A2780, HUT-78 and THP-1 cell lines was higher than that of miltefosine. The compounds showed antiprotozoal activity against Acanthamoeba lugdunensis and Acanthamoeba quina. Some of them also possess fungicidal activity against Candida albicans equal to miltefosine. No antibacterial activity was observed against Staphylococcus aureus and Escherichia coli. A difference in position of a long hydrocarbon chain within the structure with maximum efficacy was observed for antitumour, antiprotozoal and antifungal activity.

Cationic lipids constitute a family of synthetic vectors commonly used for nucleic acids delivery. We herein report the results of a systematic study that aimed to compare the transfection efficacies of cationic lipophosphoramidates possessing either two identical lipid chains (termed symmetric cationic lipids) or two different lipid chains (non-symmetric cationic lipids). In addition, we also compared the transfection results of such a 'molecular approach' (the two different lipid chains being included in the same molecule) with those of a 'supramolecular approach' in which two types of symmetrical cationic lipids were mixed in one liposomal formulation. Thus, the present work allowed us first to optimize the methods used to synthesize non-symmetric cationic lipophosphoramidates. In addition, we could also identify two non-symmetric cationic lipids exhibiting high transfection efficiencies with a series of mammalian cell lines, both vectors being characterized by a single phytanyl chain and either an oleyl or a lauryl lipid chain.

A novel, efficient one-pot method has been developed to synthesize amphiphiles such as N-alkylated/N-allylated triethyl-amines and pyridinium salts for the first time from n-alcohols and naturally occurring terpenes (allyl alcohols) in good yields. These amphiphiles have got industrial application as surfactants, DNA carriers, and other biological applications. The DNA delivery efficacy and cytotoxicity of N-alkylated and N-allylated triethylamine and pyridinium salts were studied. Georg Thieme Verlag Stuttgart · New York.

scheme or table, p. 6346 - 6349 (2010/06/11)
A series of dialkylphosphocholines were prepared and evaluated for their biological activity. The antiprotozoal activity was determined against Acanthamoeba lugdunensis. Compound 15 exhibited excellent trophocidal activity. None of the tested dialkylphosphocholines exhibited better fungicidal activity against Candida albicans than miltefosine. The antineoplastic activity was determined against HeLa. The most cytotoxic was compound 10, which was more active against tumor cells as against normal cells.
