Abstract: A compound includes cytotoxic agents such as microcystin and nodularin. More specifically, a modified microcystin and/or nodularin compound contains one or more modified substrates, wherein one or more modified substrates include an anchor group directly accessible or transformable for use in conjugation chemistry (incl. click chemistry), for the attachment of a targeting moiety. This compound is useful for cancer treatment.

Abstract: A method is used for producing a modified non-ribosomal peptide, e.g. a modified microcystin and/or modified nodularin (together CA), including the steps of: a) growing a modified non-ribosomal peptide producing cyanobacteria strain in a culture media, h) adding one or more modified substrates, preferably modified amino acids to said culture, and c) inoculating the non-ribosomal peptide, producing strain the presence of said modified substrates. The thus modified non-ribosomal peptide may be used for the therapy of various diseases.
