  • Patent number: 8022044
    Abstract: A method and pharmaceutical composition for the enhancement of transfer of a therapeutic agent to a cell wherein the therapeutic agent is formulated in a buffer comprising a compound of Formula I: wherein: n is an integer from 2-8; X1 is a cholic acid group or deoxycholic acid group; and X2 and X3 are each independently selected from the group consisting of a cholic acid group, a deoxycholic acid group, and a saccharide group, wherein the saccharide group is selected from the group consisting of pentose monosaccharide groups, hexose monosaccharide groups, pentose-pentose disaccharide groups, hexose-hexose disaccharide groups, pentose-hexose disaccharide groups, and hexose-pentose disaccharide groups; and wherein at least one of X2 and X3 is a saccharide group.

  • Patent number: 7534769
    Abstract: This invention provides methods and compositions for enhancing transfer of an agent into a cell. The agents can include polypeptides, polynucleotides such as genes and antisense nucleic acids, and other molecules. In some embodiments, the agents are modulating agents that can modulate a cellular activity or function when introduced into the cell. The methods and compositions are useful for introducing agents into individual cells, as well as cells that are present as a tissue or organ.
