  • Publication number: 20110218156
    Abstract: In accordance with the present invention, it has been discovered that the uptake of negatively charged entities into cells can be enhanced by noncovalently associating such charged entities with molecular entities comprising an amphiphilic core with positively charged arms, wherein a plurality of lipophilic (e.g., bile acid) moieties are covalently attached to the positively charged arms. The molecular entities form well defined stoichiometric complexes with negatively charged entities. Various compositions and methods for stabilizing anionic charged entities and for enhancing the cellular uptake of any anionic charged entities, e.g. double-stranded or hairpin nucleic acid, are provided.

  • Publication number: 20100056612
    Abstract: In accordance with the present invention, it has been discovered that the uptake of charged molecules into cells can be enhanced by noncovalently associating such molecules with molecular entities comprising an amphiphilic core with oppositely charged arms. The molecular entities form well defined stoichiometric complexes with charged molecules. Various compositions and methods for stabilizing anionic charged molecules and for enhancing the cellular uptake of any anionic charged molecules, e.g. double-stranded or hairpin nucleic acid, are provided.

  • Publication number: 20100056475
    Abstract: It has been discovered that the uptake of anionic charged species into cells can be enhanced by noncovalently associating such species with specifically modified forms of cyclodextrin. The invention modified forms of cyclodextrin form well defined stoichiometric complexes with anionic charged molecules. This discovery enables one to produce various compositions containing anionic charged molecules and facilitates methods for enhancing the cellular uptake of double-stranded or hairpin nucleic acid.
