摘要:For Further Structural Studies And For Physiological Investigations Of Beta-Peptides,It Is Necessary To Have H2O-Soluble Derivatives. Thus,We Have Prepared Beta-Hexa-,Beta-Hepta-,And Beta-Nonapeptides (1-6) With Two,Three,And Seven Side Chains Of Lysine And Serine. To Detect Possible Pi-Pi Interactions,We Also Included The Beta-Amino Acid Beta(2)-Hhop,Resulting From Homologation Of So-Called Homophenylalanine (Hop) (5 And 6). The Fmoc-Beta(2)-And Beta(3)-Amino-Acid Derivatives (11-14 And 19),And The Corresponding Beta-Peptides Were Prepared By Methods Previously Described (Solid-Phase Peptide Coupling; HPLC-Pure Samples,Fig. I). Circular-Dichroism Spectra (Fig.2) Indicate The Presence Of Less Pronounced Secondary Structures (Especially Of The Lysine Analogues With Multiple Positive Charge) In H2O As Compared To Meoh. The Beta(3)-Heptapeptide (3) With Two Serine Side Chains Is Well Soluble In H2O And Exhibits The Cd Pattern Typical Of The 3(1)-Helical Structure.
