Three new metabolites of hybrid strain KO 0231, derived from Penicillium citreo-viride IFO 6200 and 4692

Three new metabolites, anthrasteroids, have been isolated from the mycelia of a hybrid strain, KO 0231, prepared by cell fusion technique using Penicillium citreo-viride IFO 6200 and 4692. Their structures were determined based on their spectral data. Furthermore, these natural products were synthesized starting from ergosterol. (C) 2000 Elsevier Science Ltd. All rights reserved.
