  Synthesis, characterization and transfection activity of new saturated and unsaturated cationic lipids

  摘要：

  We synthesized new cationic lipids, analogue to N-[1-(2,3-dioleoyloxy)propyl]-N,N,N-trimethylammonium chloride (DOTMA) and 1,2-dimyristyloxypropyl-3-dimethyl-hydroxyethylammonium bromide (DMRIE), in order to compare those containing a dodecyl chain with those having a relatively long chain with two or five double bonds, such as squalenyl and dihydrofarnesyl derivatives, or complex saturated structures, such as squalane derivatives. The fusogenic helper lipid dioleoylphosphatidylethanolamine (DOPE) was added to cationic lipids to form a stable complex. Liposomes composed of 50:50 w/w cationic lipid/DOPE were prepared and incubated with plasmidic DNA at various charge ratios and the diameter and zeta potential of the complexes were measured. The surface charge of the DNA/lipid complexes can be controlled by adjusting the cationic lipid/DNA ratio. Finally, we tested the in vitro transfection efficiency of the cationic lipid/DNA complexes using different cell lines. The transfection efficiency was highest for the dodecyloxy derivative containing a single hydroxyethyl group in the head, followed by the dodecyloxy and the farnesyloxy trimethylammonium derivatives. Instead the C27 squalenyl and C27 squalanyl derivatives resulted inactive.

  To reveal an essential biological role of menaquinone-4, we have clarified that dietary PK was converted to menaquinone-4 (MK-4) in animal tissues using deuterated vitamin K analogues. However, the kinds of analogue converted into MK-4 have not been elucidated. In this study, we examined structure-activity relationships in the conversion of several vitamin K analogues, with a substituted side chain, into MK-4 using cultured human cell lines. The results differed with the side chain of the analogues, that is, (1) the length of the isoprene unit and (2) the number of double bonds in the side chain. These findings would be useful for clarifying the mechanism of conversion of other vitamin K homologs into MK-4 as well as related enzymes. (c) 2010 Elsevier Ltd. All rights reserved.
