ABSTRACT
Two dimeric spermine-choloyl conjugates were synthesized and found to be capable of promoting the transport of anions across egg-yolk L-α-phosphatidylcholine-based liposomal membranes, via an anion-exchange mechanism and with moderate selectivity with respect to monoanionic ions. A Hill analysis indicated that these two conjugates exhibited similar aggregation behaviors. However, the conjugate bearing a rigid p-bis(aminomethyl)benzene moiety functioned more efficiently than the analogue having a flexible putrescine linker.
