We have synthesized rigid analogues of combretastatin bearing a furan ring in place of the olefinic bridge.These compounds are cytotoxic at nanomolar concentrations in neuroblastoma cells, display a similarstructure-activity relationship compared to combretastatin A4, and inhibit tubulin polymerization. We alsoshow that the furan ring can be further functionalized. Thus, it is possible that combretafurans could act asscaffolds for the development of dual-action antitumoral agents.
