The absolute configuration of the pentacyclic ichthyotoxin stypotriol, a constituent of Stypopodium zonale, was deduced to be 3S,5R,8R,9R,10S,13S,14S-(-) -1 by vibrational circular dichroism spectroscopy of the derived ...

Biological transformation of the meroditerpenoid, stypotriol triacetate (1) by the fungi Aspergillus niger, Cunninghamella elegans, Gibberella fujikuroi and Mucor plumbeus was studied. The incubation of 1 with A. niger ...

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. © 1992.

The sea constitutes one of the most promising sources of novel compounds with potential application in human therapeutics. In particular, algae have proved to be an interesting source of new bioactive compounds. In this ...

The marine metabolites pacifenol, stypotriol triacetate and epitaondiol were tested for their effects on a number of inflammatory responses. Epitaondiol exhibited a potent topical anti-inflammatory activity related to ...

The absolute configuration of alga meroditerpenoids (-)-taondiol diacetate (1b) and (+)-epitaondiol diacetate (2c) are assigned by vibrational circular dichroism (VCD). The spectra of (2S,3S,6R,7R,10R,11R,14S)-1b and ...
