Chemical defence of the mediterranean alga Caulerpa taxifolia: variations in caulerpenyne production
Variations in Cyn concentration explained seasonal changes in feeding behaviour of the sea urchin Paracentrotus lividus and biomass of fouling organisms of C. taxifolia. Expand
Antiprotozoal steroidal saponins from the marine sponge Pandaros acanthifolium.
The chemical composition of the Caribbean sponge Pandaros acanthifolium was reinvestigated and led to the isolation of 12 new steroidal glycosides, namely, pandarosides E-J and their methyl esters (7-12), which showed in vitro activity against three or four parasitic protozoa. Expand
Variations in Caulerpenyne Contents in Caulerpa taxifolia and Caulerpa racemosa
It would appear that when the algae are in competition with P. oceanica, Caulerpa is more inclined to accelerate vegetative growth (competition for light) than to produce secondary metabolites. Expand
Elysia subornata (Mollusca) a potential control agent of the alga Caulerpa taxifolia (Chlorophyta) in the Mediterranean Sea
The biological characteristics of Elysia subornata were studied in an aquarium to assess its risks and chance of success as a potential biological control agent against the invasive alga Caulerpa taxifolia in the Mediterranean Sea. Expand
Antimicrobial activities of marine sponges from the Mediterranean Sea
Those sponges which contain a large quantily of symbiotic bacteria display a weak antifungal activity, and the distribution of antimicrobial activities against five classes of microorganisms among 28 species of marine demosponges is reported. Expand
Isolation, structural identification and biological activity of two metabolites produced by Penicillium olsonii Bainier and Sartory.
From the culture broth of a fungus, two metabolites have been isolated: bis(2-ethylhexyl)phthalate (DEHP) precedently isolated from Streptomyces sp. and 2-(4-hydroxyphenyl)-2-oxoacetaldehyde oximeExpand
Caulerpenyne from Caulerpa taxifolia has an antiproliferative activity on tumor cell line SK-N-SH and modifies the microtubule network.
Analysis by electron microscope indicated that caulerpenyne induced aggregation of tubulin, which may be responsible for inhibition of microtubule polymerization and bundling of residual microtubules in neuroblastoma SK-N-SH cell line. Expand
Traditional remedies used in the western Pacific for the treatment of ciguatera poisoning.
A list of plants used in treating ciguatera poisoning in the Western Pacific region is presented, with emphasis on species whose exact utilization has been determined. Expand
The marine sponge Plakortis zyggompha: a source of original bioactive polyketides
Abstract Three new spiculoic acids 1 – 3 and two members of a new closely related family of natural products named zyggomphic acids 4 and 5 were isolated from the very little studied marine spongeExpand
Bioactive guanidine alkaloids from two Caribbean marine sponges.
Seven new guanidine alkaloids (1-7) together with the known batzelladines A, F, H, and L, ptilomycalin A, and fromiamycalin were isolated from the Caribbean marine sponges Monanchora arbuscula andExpand
