Incorporations of sodium [1,2-C-13(2)]acetate and sodium [1-C-13,O-18(2)]acetate confirmed that murayaquinone, produced by Streptomyces murayamaensis, is a polyketide. However, the labeling patterns revealed that a simple folding of the decaketide intermediate does not lead directly to the final phenanthrene skeleton. Instead a different phenanthrene is apparently formed that undergoes an oxidative cleavage, isomerization, and re-closure to a new phenanthrene skeleton. (C) 1997 Elsevier Science Ltd.

Disclosed are methods relating to the use of kinamycin F as an anti-cancer agent. Cytotoxic methods induced by kinamycin F include DNA and protein damage and topoisomerase inhibition. As set forth herein, the anti-cancer effects of kinamycin F may be attributed to, for example, DNA binding, DNA intercalation, topoisomerase Ilα decatenation activity inhibition and/or production of radical species by kinamycin F.
