ABSTRACT
The structures of the commercially available microginins 674 and 690 isolated from a cultured strain of Microcystis aeruginosa and only recently characterized have been revisited. Using NMR and HRMS/MS data, an inversion of two amino acids, N-methylmethionine and tyrosine, in the structure of these metabolites is unambiguously demonstrated. These results highlight the importance of careful examination of spectroscopic data for the proposition of structures of natural products, especially when they are of commercial value.
