...Different microcystin congeners vary in toxicity from essentially non-toxic (e.g., [(6Z)-Adda5] microcystin-LR,LD50 > 1200 mg kg 1) to highly toxic (e.g., microcystin-LR, LD50 = 50 mg kg 1; Rinehart et al., 1994)....

...Microcystins are cyclic heptapeptides which contain a unique b-amino acid, Adda (3-amino-9-methoxy2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid; Rinehart et al., 1988; Tillett et al., 2000)....

...spumigena produces nodularin, a cyclic pentapeptide hepatotoxin with the structure of cyclo(-D-erythro-b-methyl-Asp-LArg-Adda-D-Glu-N-methyldehydro-b-aminobutyric acid), in which Adda is (2S,3S,8S,9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid (29, 36)....

...Interestingly, the revised structure contains a phosphonate analog of dehydroalanine, which is found in many natural products such as the lantibiotics (127), microcystins (128), and thiostrepton (129)....
