  • Patent number: 6187760
    Abstract: A novel class of cationic phospholipids and novel method for their synthesis are disclosed. The class of phospholipids comprises phosphotriester derivatives of phosphoglycerides and sphingolipids. It has been unexpectedly found that liposomes comprising one or more of these cationic phospholipids are effective in the lipofection of nucleic acids. These novel phospholipids are particularly attractive because of they are not only effective in lipofection, but are extremely cheap and easy to male.
    Type: Grant
    Filed: February 5, 1999
    Date of Patent: February 13, 2001
    Assignee: Northwestern University
    Inventors: Gary W. Ashley, Robert C. MacDonald, Miho Shida
  • Patent number: 5891714
    Abstract: Cationic phospholipids and their use in treating pathogen-associated disease are disclosed. The class of phospholipids comprises the phosphotriester derivatives of phosphoglycerides and sphingolipids. Liposomes comprising one or more of the cationic phospholipids are effective in the lipofection of nuclidic acids and are therefore useful in methods of treating disease.
