Diversity of cultivable fungi associated with Antarctic marine sponges and screening for their antimicrobial, antitumoral and antioxidant potential
The results suggest that fungi associated with Antarctic sponges, particularly Geomyces, would be valuable sources of antimicrobial and antitumoral compounds. Expand
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.
Triterpenoids from Azorella trifurcata (Gaertn.) Pers and their effect against the enzyme acetylcholinesterase
This is the first report of three lanostane- and two cycloartane-type triterpenes in the genus Azorella and their effect on the enzyme acetylcholinesterase was assessed. Expand
Unusual chlorinated pregnanes from the eastern Pacific octocoral Carijoa multiflora
Abstract Two unique chloro-pregnane steroids have been isolated from the eastern Pacific octocoral Carijoa multiflora and their structures and stereochemistries were determined on the basis ofExpand
Neo-clerodane diterpenoids from Baccharis incarum
Abstract A new neo-clerodane diterpenoid was isolated from the aerial parts of Baccharis incarum together with the previously known diterpenoids bacchalineol and barticulidiol.
Halogenated sesquiterpenes pacifenol and pacifenol derivatives on the aphid Schizaphis graminum
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
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
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
