| Abstract | Three new pairs of biologically active regioisomeric toxins (AAL toxins TC, TD, and TE) were isolated from liquid cultures of Alternaria alternata f. sp. lycopersici, purified using standard chromatographic procedures, and their structures elucidated following interpretation of spectra obtained from NMR and mass spectrometry experiments. Each of the toxin congeners is structurally similar to the AAL toxin TA, which was characterized earlier from culture filtrates of this fungus. AAL toxin TC resembles TA but differs in its lack of hydroxyl groups at C 4 and C 5 . AAL toxin TE is the N-acetylated form of TC [...] |
