Synthesis and Ion Channel Formation of Novel Cyclic Peptides Containing a Non-natural Amino Acid
A series of novel cyclic peptides possessing an alternate natural / non-natural amino acid sequence were prepared from <FONT SIZE=-2>L</FONT>-alanine and 5-(<I>N</I>-acylamino)-3-aminobenzoic acid with a long acyl chain. Upon examination by the voltage clamp method, membranes composed of the synthetic cyclic peptides with varying ring sizes and side-chain lengths were found to form cation selective channels with a conductance of <I>ca</I>. 9 pS in aqueous KCl (500 mM).
