Peptide-appended pillar[n]arene (n = 5, 6) derivatives have been synthesized. 1H NMR and IR studies reveal that the molecules adopt a tubular conformation in solution and lipid bilayer membranes. Kinetic measurements using the fluorescent labeling method with lipid vesicles reveals that these molecules can efficiently mediate the transport of amino acids across lipid membranes at a very low channel-to-lipid ratio (EC50 = 0.002 mol%) and, in several cases, chiral selectivity for amino acid enantiomers can be achieved, which features one of the key functions of natural amino acid channels.
