The present invention relates to methods and compositions for the transformation of cells. In particular, compositions and methods are disclosed which include combinations of the nucleic acid of interest and polyhydroxylated or polyglycosylated steroid molecules. Most preferably, exogenous or endogenous nucleic acid is contacted with the cell in the presence of a bile acid (e.g., cholic acid) derivatized with an amine-containing side chain.

摘要:
The application discloses steroidal glycoside compounds, especially spirostanyl glycosides, which have a glycosyl group O-linked to the C-3 hydroxy radical of the steroid and where the moieties at the C-10 and C-11 positions of the steroid are the same or different and are selected from the group consisiting of methylene, hydroxy and carbonyl. These steroid glycosides are useful as hypocholesterolemic agents and anti-atherosclerosis agents.
