Structures of the metabolites employed in this study and their proposed reaction pathways. a. Structures of (–)-lomaiviticin A (1), (–)-lomaiviticin C (2), (–)-kinamycin C (3), and the diazotetrahydrobenzo[b]fluorene (diazofluorene, 4) functional group. b. Cytotoxic species proposed to form from the 1-diazo-1H-indene-4,7-dione. Red denotes the 1-diazo-1H-indene-4,7-dione functional group of 1, 2, and 3. Blue denotes the hydrofulvene functional group of 2.
