摘要：

Cationic lipid polyamine amides (cholan-24-amides) have been prepared from chenodeoxycholic (3 alpha,7 alpha-dihydroxy), ursodeoxycholic (3 alpha,7 beta-dihydroxy), and deoxycholic (3 alpha,12 alpha-dihydroxy) bile acids (5 beta-cholanes) by acylation of tri-Boc protected spermine. Their relative binding affinities for calf thymus DNA were determined using an ethidium bromide displacement assay. These lipopolyamine amides are synthetic vectors for non-viral gene delivery and models for lipoplex formation with respect to lipofection, a key first step in gene therapy.
