Liverwort constituents have been reported to exert a broad spectrum of biological activities. In this study, we used a bioactivity-guided separation of an extract from the liverwort species Marchantia emarginata subsp. tosana to determine its anticancer activity. A high level of the active

Microtubules are long-standing targets in cancer chemotherapy. Previously, we reported that marchantin C triggers apoptosis of human tumor cells. We show here that marchantin C induced cell cycle arrest at G(2)/M phase in A172 and HeLa cells. In addition, marchantin C decreased the quantity of

Four new cytotoxic 8,9-secokauranes have been identified from the liverwort Lepidolaena taylorii. The 11-oxygenation found in three of these has not been encountered in the 8,9-secokauranes known from higher plants. NMR studies were combined with molecular modelling to determine the preferred

Three new metabolites, asperfumigatin (1), isochaetominine (10), and 8'-O-methylasterric acid (21), together with nineteen known compounds, were obtained from the culture of Aspergillus fumigatus, an endophytic fungus from the Chinese liverwort Heteroscyphus tener (Steph.) Schiffn. Their structures

Plants of the Radula genus are chemically very distinct from the other liverworts since they mainly elaborate bibenzyls including bibenzyl cannabinoids and prenyl bibenzyl derivatives, as well as bis-bibenzyls. Several of these components show biological activities such as psychoactivity,

It is generally accepted that the origin of the cytotoxicity of ent-kaurane diterpenoids is due to the formation of reactive oxygen species (ROS) and that the α,β-unsaturated carbonyl is a pivotal moiety. Herein we demonstrate the isolation of 32 new and 12 known ent-kaurane diterpenoids from two
