Structures of anabaenolysins A–D (compounds 1–4) and α-, β-, and γ-cyclodextrins (compounds 5–18). The newly discovered anabaenolysins C and D differ mainly in the glutamine in position 3 from anabaenolysins A and B, which have a glycine molecule in position 3. Ac, acetyl; AHFA, (5E,7E,9E)-3-amino-2-hydroxyoctadeca-5,7,9,17-tetraenoic acid; AOFHA, (3-amino-5-oxotetrahydrofuran-2-yl)(hydroxy)acetic acid; CD, cyclodextrin.
