Bioactive Diterpenoids from Clerodendrum kiangsiense.
A new abeo-abietane diterpenoid, 12-methoxy-6,11,14,16-tetrahydroxy-17(15→16)-abeo-5,8,11,13-abietatetraen-3,7-dione (8), was isolated from the hydroalcoholic extract of the herb of Clerodendrum kiangsiense along with seven known diterpenoids (1-7). Their structures were identified on the basis of spectroscopic analyses including two-dimensional NMR and comparison with literature data. All of t...
متن کاملBioactive Chromodorolide Diterpenes from an Aplysillid Sponge
The known chromodorolides A (1) and B (2), and a new derivative chromodorolide C (3) have been isolated from an Australian sponge and characterized by 1D and 2D NMR experiments. The chromodorolides exhibited significant cytotoxicity against the P388 mouse leukaemia cell line, and also showed activity against the freeliving larval stages of the parasitic nematodes Haemonchus contortus and Tricho...
متن کاملBioactive Segetane, Ingenane, and Jatrophane Diterpenes from Euphorbia taurinensis.
A novel segetane (1: ) and jatrophane diterpene (2: ), together with five known diterpenoids possessing segetane (3: ), jatrophane (4: ), and ingenane skeletons (5 - 7: ), were isolated from the methanol extract of Euphorbia taurinensis All. The structure elucidation of the compounds was performed by means of extensive spectroscopic analysis, including HRESIMS and 1D (1H, J-modulated spin-echo ...
متن کاملBioactive Isopimarane Diterpenes from the Fungus, Epicoccum sp. HS-1, Associated with Apostichopus japonicus
One new isopimarane diterpene (1), together with two known compounds, 11-deoxydiaporthein A (2) and iso-pimara-8(14),15-diene (3) were isolated from the culture of Epicoccum sp., which was associated with Apostichopus japonicus. Their structures were determined by the analysis of 1D and 2D NMR, as well as mass spectroscopic data. The absolute configuration of Compound 1 was deduced by a single-...
متن کاملBioactive diterpenes and sesquiterpenes from the rhizomes of wild ginger (Siphonochilus aethiopicus (Schweinf) B.L Burtt).
Wild ginger (Siphonochilus aethiopicus (Schweinf) B.L Burtt) is used in traditional medicines in the West and South of Africa. In the present study, the crude hexane extract of wild ginger was evaluated for in vitro bioactivity. The components isolated from the plant for the first time are: epi-curzerenone, furanodienone (sesquiterpenes), 8(17),12E-labdadiene-15,16-dial, 15-hydroxy-8(17),12E-la...
