Isoepitaondiol, a diterpenoid of Stypopodium flabelliforme and the insecticidal activity of stypotriol, epitaondiol and derivatives
Abstract A new diterpenoid of mixed biogenesis; isoepitaondiol, has been isolated together with known diterpenoids and two chromones from the alga Stypopodium flabelliforme collected at Easter Island.
SECONDARY METABOLITES FROM MARINE PENICILLIUM BREVICOMPACTUM
TLDR
In a screening of Basidiomycete cultures isolated from marine invertebrates collected along the Chilean coastline, a Penicillium brevicompactum strain was identified as a producer of metabolites inhibiting the growth of bacteria and fungi. Expand
Halogenated sesquiterpenes pacifenol and pacifenol derivatives on the aphid Schizaphis graminum
TLDR
Toxicity of pacifenol was lower than the other compounds, and the dibromo derivative was more toxic than pacifidiene. Expand
Steroids from Aquatic Organisms, XIX. New Sterols from the Antarctic Sponge Artemisina apollinis
Abstract The steroidal composition of the sponge Artemisina apollinis from the Antarctic Ocean was studied by GC-MS and 'H NMR. The sponge contains twenty-eight C 25—C30 derivatives having fourExpand
Biotransformation of the marine sesquiterpene pacifenol by a facultative marine fungus
TLDR
Continued investigation of the marine alga Laurencia claviformis has led to the isolation of pacifenol, a halogenated sesquiterpene as the major metabolite, and the structure was elucidated on the basis of spectroscopic data. Expand
Neo-clerodane diterpenoids from Baccharis rhomboidalis
Abstract Three new neo-clerodane diterpenoids were isolated together with other known clerodanes from Baccharis rhomboidalis . Their structures were established by spectroscopic methods.
Anti-Proliferative Activity of Meroditerpenoids Isolated from the Brown Alga Stypopodium flabelliforme against Several Cancer Cell Lines
TLDR
Six meroditerpenoids isolated from the brown alga Stypopodium flabelliforme showed good activity against all cell lines, with SH-SY5Y and RAW.267 being the most susceptible to antimicrobial activity. Expand
A New C15 Acetogenin from the Marine Alga Laurencia claviformis
Abstract (3Z)-13-epipinnatifidenyne 1, a novel C15 acetogenin, has been isolated together with others five known compounds from the red alga Laurencia claviformis, a species endemic to Easter Island.Expand
Insecticide and acaricide activities of polyhalogenated monoterpenes from chilean Plocamium cartilagineum
TLDR
Four new alicyclic monoterpenes based on the 1-(2-chlorovinyl)-2,4, 5-trichloro-1,5-dimethylcyclohexane skeleton were isolated from Plocamium cartilagineum from the Chilean coast and the structure of the new compounds were determined by comparison of the spectral data with those of known compounds. Expand
NEW BUTYROLACTONE FROM A MARINE-DERIVED FUNGUS ASPERGILLUS SP
Four compounds that belong to two structure types, namely dibenzylbutyrolactone and sesterterpenoids, were obtained from the extract of the strain Aspergillus sp. (2P-22), isolated from a marineExpand
