New phomopsolides from a Penicillium sp.
Investigation of the bioactive compounds from a Penicillium sp. isolated from the inner bark of the Pacific yew, Taxus brevifolia, led to the isolation of the known furanone 1, and a series of phomopsolides. The phomopsolide fractions contained phomopsolides A and B, which have previously been described, and three new phomopsolides. The structures of the new phomopsolides were deduced by comparison of their NMR spectra to those of the known compounds.
