HPLC-MS elution profiles of novel metabolites of the meleagrin/neoxaline pathway. The HPLC-MS total ion chromatogram (black) and normalized extracted ion chromatograms (colored) of the novel secondary metabolites roquefortine N (12, 15.1 min), roquefortine M (11, 16.5 min), roquefortine L (6, 16.8 min), neoxaline (10, 17.8 min), and roquefortine F (9, 22.8 min) from the meleagrin/neoxaline pathway are shown.
