Nodularin-R is a cyclic nonribosomal peptide produced by the planktonic cyanobacterium Nodularia spumigena.[1] This cyanobacterium forms blooms in brackish water bodies throughout the world. The late summer blooms of Nodularia spumigena are among the largest cyanobacterial mass occurrences in the world. Nodularin-R is a pentapeptide and contains several unusual non-proteinogenic amino acids such as methyldehydrobutyrine and the β-amino acid ADDA ((all-S,all-E)-3-Amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-diene acid). Nodularin-R is a cyanotoxin and poses a health risk for wild and domestic animals as well as humans. Nodularin-R is a potent hepatotoxin and may cause serious damage to the liver.
