Figure 1. Residue labelling scheme for CsA-analogues (see also Table 1). Atom labelling is according to the IUPAC convention. CN is the methyl carbon atom of the N-methylated amino acids. MLE for MeLeu; MVA for MeVal; BMT for MeBmt; ABU for Abu; SAR for Sar; VAL for Val; ALA for Ala; DAL for D-Ala. All amino acid residues with the exception of D-Ala8 (and Sar3) are in the L-configuration.
