Notes:
The assignment of proton NMR signals and the conformational analysis of N-(Gly)-[Lys8]-vasopressin and N-(Gly—Gly—Gly)—[Lys8]-vasopressin in dimethyl sulfoxide solution by means of one- and two-dimensional NMR techniques are presented. Dihedral angles obtained from 3J (HN—C—α-H) vicinal couplings, intramolecular distances estimated from nuclear Overhauser enhancements (NOEs) and two-dimensional experiments in the rotating frame (ROESY), as well as temperature dependences of the amide protons, suggest a more or less rigid ring conformation with an inverse γ-turn for both cyclic peptides.
