Abstract |
|
|
|
The synthesis of the acyclic nucleolipid 2-dimyristoyl-sn-glycerol thymine phosphate 5 (diC14-T) was achieved starting from thymidine 1 through conventional phosphoramidite chemistry. This simple synthetic strategy, which provides the pure (R) enantiomer is amenable to a large diversity of natural diacyl glycerol. Transfection experiments realized on mammalian cells in the presence of Ca2+ revealed that the acyclic anionic 1,2-dimyristoyl-sn-glycerol 5 (diC14-T) was as efficient as its cyclic analogue counterpart diC14-3’-dT to deliver plasmid DNA into cells.
