Use of plant extracts in fish aquaculture as an alternative to chemotherapy: Current status and future perspectives
The studies carried out on the use of plant products on fish aquaculture and their biological effects on fish such as growth promoter, immunostimulant, antibacterial and anti-parasitic are reviewed. Expand
Sources of Secondary Metabolite Variation in Dysidea avara (Porifera: Demospongiae): The Importance of Having Good Neighbors
It is shown for the first time that sponges are able to increase production or accumulation of secondary metabolites in their peripheral zone depending on the nature of their neighbors and opens new biotechnological approaches to enhance the metabolite yield in sponge cultures. Expand
Structures and antimicrobial activities of pyridoacridine alkaloids isolated from different chromotypes of the ascidian Cystodytes dellechiajei.
Three new pentacyclic alkaloids were isolated from different chromotypes of the western Mediterranean ascidian Cystodytes dellechiajei to evaluate the antimicrobial potential and elucidate the structures of all compounds on the basis of spectroscopic data. Expand
Binding to DNA and cytotoxic evaluation of ascididemin, the major alkaloid from the Mediterranean ascidian Cystodytes dellechiajei.
It is suggested that DNA, but not topoisomerases, may represent the critical cellular target at which this marine alkaloid exhibits its potent cytotoxic properties in vitro. Expand
Photolysis of tembotrione and its main by-products under extreme artificial conditions: comparison with another β-triketone herbicide.
Investigation of the photolytic behaviour of tembotrione found that degradation was dependent on pH and occurred more rapidly under acidic and neutral conditions, leading predominantly to the formation of a xanthenedione type compound by intramolecular cyclisation with loss of HCl. Expand
New pyridoacridine alkaloids from the purple morph of the ascidian Cystodytes dellechiajei
Two new pyridoacridine alkaloids, 13-didemethylaminocycloshermilamine D (1) and demethyldeoxyamphimedine (2), were isolated from the purple chromotype of the Western Mediterranean ascidian CystodytesExpand
Additional cytotoxic pyridoacridine alkaloids from the ascidian Cystodytes violatinctus and biogenetic considerations.
The structures of four new members of this family, shermilamine F, dehydrokuanoniamine F, and arnoamines C and D, were elucidated on the basis of NMR and MS data and by comparison with data of known compounds isolated from this genus. Expand
Total synthesis of the marine pentacyclic alkaloid meridine
Abstract The synthesis of the marine pyridoacridine alkaloid meridine (1) has been accomplished in eight steps from 2,5-dimethoxy-3-nitroaniline in 9% overall yield.
New Lobane and Cembrane Diterpenes from Two Comorian Soft Corals
Preliminary biological investigation of a collection of Comorian soft corals resulted in the selection of two specimens, one of Sarcophyton and the other of Lobophytum, on the basis of their toxicityExpand
Two cell differentiation inducing pyridoacridines from a marine sponge Biemna sp. and their chemical conversions
Two pyridoacridines, N-hydroxymethylisocystodamine (1) and neolabuanine A (2), together with the known ecionine A (3), ecionine B (4), isocystodamine (5), N-methylisocystodamine (6),Expand
