Popis: | Four new nor- and bisnorditerpene dilactones, makilactones A-D, were isolated from a MeOH extract of bark and root of Podocarpus macrophyllus D. Don (Podocarpaceae) with three known diterpene dilactones. The structures of the new nor- and bisnorditerpene dilactones having a 7:8, 9:11-dienolide moiety were determined by the spectroscopic studies, including 1D and 2D NMR spectral analysis, and single crystal X-Ray crystallographic analysis. Two of the presently isolated compounds were shown to be very strongly cytotoxic. |
