Abstract A family of hydraphile ionophores has been prepared in which various∼ CH 2 N∼ to∼ CON∼ replacements have been made to assess the effect on Na+ transport through phospholipid bilayers. When the central relay (see graphical abstract) was a third macrocycle, symmetrical carbonyl for methylene replacements enhanced activity, but the presence of four or six amide residues diminished transport. When a pair of amides was ...
