title: Epoxytwinol A, a novel unique angiogenesis inhibitor with C2 symmetry, produced by a fungus.
abstract: We isolated a novel unique pentaketide dimer designated as epoxytwinol A from the fermentation broth of a fungus. The structure of epoxytwinol A was determined to have a new carbon skeleton with C(2) symmetry by elucidation of spectroscopic evidence. Epoxytwinol A inhibited endothelial cell migration stimulated by vascular endothelial growth factor (ED(100)= 2.6 microM).
