A dendritic approach to the construction of a homologous series of pore-forming amphiphiles has been developed, based on the use of spermidine, spermine, lysine, and cholic acid. A kinetic analysis of Na+ transport across bilayers of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine by three dendritic amphiphiles has provided the strongest evidence to date for a barrel stave structure.
