Asymmetric (left) and symmetric (right) conformations of the two cyclic octadepsipeptides PF1022A (1) and emodepside (2) consisting of four l-N-methyl leucines (Mle), two d-lactic acid moieties (d-Lac) and two d-phenyllactic acid moieties (d-Phl) (with additional morpholine rings in para position in case of 2 (d-Phm)). In the C2 symmetric conformation, the chemically equivalent residues share a common designation derived from their position in the asymmetric conformation.
