Isolation and structure determination of two new hydrophobic microcystins from Microcystis sp. (CAWBG11)

Puddick, Jonathan; Prinsep, Michèle R.; Wood, Susanna A.; Cary, S. Craig; Hamilton, David P.; Wilkins, Alistair L. (Elsevier, 2013)

Two new hydrophobic microcystins, microcystin-FA (1) and microcystin-WA (2), were isolated from the cyanobacterium Microcystis sp. (CAWBG11). The structures were deduced using one- and two-dimensional nuclear magnetic ...
Structural characterization of new microcystins containing tryptophan and oxidized tryptophan residues

Puddick, Jonathan; Prinsep, Michèle R.; Wood, Susanna A.; Miles, Christopher O.; Rise, Frode; Cary, S. Craig; Hamilton, David P.; Wilkins, Alistair L. (MDPI, 2013)

Microcystins are cyclic peptides produced by cyanobacteria, which can be harmful to humans and animals when ingested. Eight of the (more than) 90 microcystin variants presently characterized, contain the amino acid tryptophan. ...
