Popis: The spiroxins (1–5) were purified from the culture extract of a marine-derived fungus. Their unique bisnaphthospiroketal structures were established by NMR spectroscopy. In addition to cytotoxicity, these compounds showed antibiotic activity and were active in a mouse xenograft model against human ovarian carcinoma. The mechanism of action of these compounds was shown to be due, in part, to their effect on DNA.
