Kibdelones are natural aromatic polyketides first isolated from an actinomycete, Kibdelosporangium. They exhibit potent and selective cytotoxicity against a panel of human tumor cell lines. Kibdelones also display significant antibacterial and nematocidal activity. Kibdelone B is a member of this group that undergoes facile equilibration to kibdelones A-C under mild conditions. Its mode of action and pharmacology have not been studied.

Kibdelones: novel anticancer polyketides from a rare Australian actinomycete
Chemistry 2007;13(5):1610-9.PMID:17091523DOI:10.1002/chem.200601236.
The kibdelones are a novel family of bioactive heterocyclic polyketides produced by a rare soil actinomycete, Kibdelosporangium sp. (MST-108465). Complete relative stereostructures were assigned to kibdelones A-C (1-3), Kibdelone B rhamnoside (5), 13-oxokibdelone A (7), and 25-methoxy-24-oxokibdelone C (8) on the basis of detailed spectroscopic analysis and chemical interconversion, as well as mechanistic and biosynthetic considerations. Under mild conditions, kibdelones B (2) and C (3) undergo a facile equilibration to kibdelones A-C (1-3), while Kibdelone B rhamnoside (5) equilibrates to a mixture of kibdelone A-C rhamnosides (4-6). A plausible mechanism for this equilibration is proposed and involves air oxidation, quinone/hydroquinone redox transformations, and a choreographed sequence of keto/enol tautomerizations that aromatize ring C via a quinone methide intermediate. Kibdelones exhibit potent and selective cytotoxicity against a panel of human tumor cell lines and display significant antibacterial and nematocidal activity.
