  Synthesis and Gene Transfer Activities of Novel Serum Compatible Reducible Tocopherol-Based Cationic Lipids

  摘要：

  The molecular structure of the cationic lipids greatly influences their transfection efficiency. High transfection efficiencies of tocopherol-based simple monocationic transfection lipids with hydroxylethyl headgroups were recently reported by us (Kedika, B., et al. J. Med. Chem. 2011, 54 (2), 548-561). Toward enhancing the transfection efficiency of tocopherol-based lipids, we have synthesized two tocopherol-based dicationic lipids (1 and 2) using simple cystine in the headgroup region. The efficiency of tocopherol-based lipids (1 and 2) were compared with nontocopherol-based lipids (3 and 4) with cystine in the headgroup region. We report also a comprehensive structure-activity relationship study that identified tocopherol-based gemini cationic lipid 1 is a better transfecting agent than its monomeric lipid counterpart 2 and two other nontocopherol-based gemini cationic lipids (3 and 4). The transfection efficiency of lipid 1 was also greater than that of commercial formulation in HepG2 cell lines. A major characteristic feature of this investigation is that serum does not inhibit the transfection activity of tocopherol-based lipids (1 and 2) in general and in particular lipid 1 which is found to be highly serum-compatible even at higher concentrations of serum when compared to its monomeric counterpart lipid 2 and the other two control lipid analogues 3 and 4.
