title: Antitumor activity of fungal metabolites: verrucarin beta-9, 10-epoxides.
abstract: Verrucarins A (4) and B (5) and verrucarin A acetate, in vivo antileukemic inactive fungal metabolites, have been oxidized with m-chloroperoxybenzoic acid to give verrucarin beta-9,10-epoxides which show high in vivo activity against P388 mouse leukemia.
