title: Interaction of monobenzamidine-linked trypanocides with the Trypanosoma brucei P2 aminopurine transporter.
abstract: Single benzamidine group-carrying compounds were shown to interact with the Trypanosoma brucei P2 aminopurine transporter. Replacement of the amidine with a guanidine group decreased affinity. Trypanocidal activity was evident, but compounds were equally toxic against trypanosomes lacking the P2 transporter, which indicates additional uptake routes for monobenzamidine-derived compounds.
