Application

Cholesteryl 3β-N-(di­methyl­amino­ethyl)­carbamate hydrochloride has been used as a bilayer-membrane stabiliser and for nucleic acid transfer.
This cationic cholesterol derivative forms liposomes with L-α-phosphatidylethanolamine, dioleoyl, that efficiently transfect mammalian cell lines.

A novel cationic derivative of cholesterol, 3 beta [N-(N',N'-dimethylaminoethane)-carbamoyl] cholesterol (DC-Chol), has been synthesized and used to prepare sonicated liposomes with dioleoylphosphatidylethanolamine. This novel cationic liposome reagent facilitates efficient DNA mediated transfection in A431 human epidermoid carcinoma cells, A549 human
