A new xenicane norditerpene from the Indian marine gorgonian Acanthogorgia turgida
Manzo, E.; Ciavatta, M.L.; Gavagnin, M.; Villani, G.; Quaranta, C.; DeSouza, L.; Cimino, G. (Taylor & Francis, 2009)Chemical investigation of the liposoluble extract of the gorgonian Acanthogorgia turgida, from Indian coasts, led us to isolate a new xenicane-based norditerpene, isoacalycixeniolide-A (1), along with the known structurally ... -
Chemistry of the nudibranch Aldisa andersoni: Structure and biological activity of phorbazole metabolites
Nuzzo, G.; Ciavatta, M.L.; Kiss, R.; Mathieu, V.; Leclercqz, H.; Manzo, E.; Villani, G.; Mollo, E.; Lefranc, F.; DeSouza, L.; Gavagnin, M.; Guido Cimino, G. (MDPI Publishing, 2012)A chemical study of the Indo-Pacific dorid nudibranch Aldisa andersoni resulted in the isolation of five chlorinated phenyl-pyrrolyloxazoles belonging to the phorbazole series. Two new molecules, 9-chloro-phorbazole D and ... -
Kahalalide F analogues from the mucous secretion of Indian sacoglossan mollusc Elysia ornata
Ciavatta, M.L.; PrabhaDevi; Carbone, M.; Mathieu, V.; Kiss, R.; Casapullo, A.; Gavagnin, M. (Elsevier, 2016)Bioassay-guided fractionation of the CHCl<sub>3</sub>/MeOH extract of Elysia ornata mucus showing antifungal activity led us to isolate kahalalide F(KF) along with two unprecedented related peptides. The structures of ... -
New bioactive hydrogenated linderazulene-derivatives from the gorgonian Echinogorgia complexa
Manzo, E.; Ciavatta, M.L.; Gresa, M.P.L.; Gavagnin, M.; Villani, G.; Naik, C.G.; Cimino, G. (Elsevier, 2007)Chemical analysis of the secondary metabolite pattern of the gorgonian Echinogorgia complexa, collected along South Indian coasts, showed the presence of two new tricyclic guaiane furanosesquiterpenes, iso-echinofuran (3) ... -
New C sub(21) Delta sup(20) pregnanes, inhibitors of mitochondrial respiratory chain,from Indopacific octocoral Carijoa sp.
Ciavatta, M.L.; Gresa, M.P.L.; Manzo, E.; Gavagnin, M.; Wahidullah, S.; Cimino, G. (Elsevier, 2004)Two new compounds, pregnanes 1 and 2, the known pregnane 3 and a series of known chlorinated prostanoids (4-9) have been isolated from the Indian octocoral Carijoa sp. Their structures have been elucidated by spectroscopic ... -
New caulerpenyne-derived metabolites of an Elysia Sacoglossan from the south Indian coast
Ciavatta, M.L.; Gresa, M.P.L.; Gavagnin, M.; Manzo, E.; Mollo, E.; DeSouza, L.; Cimino, G. (Molecular Diversity Preservation International, 2006)Chemical analysis of the secondary metabolite pattern of the sacoglossan mollusc Elysia cf. expansa, collected along South Indian coasts, showed the presence of the typical Caulerpa-derived sesquiterpene caulerpenyne (1) ... -
New gamma-pyrone propionates from the Indian Ocean sacoglossam Placobranchus ocellatus
Manzo, E.; Ciavatta, M.L.; Gavagnin, M.; Mollo, E.; Wahidullah, S.; Cimino, G. (Tetrahedron letters, 2005)A new gamma-pyrone propionate, compound 9, and its peroxy derivative 10 have been isolated from the sacoglossan Placobranchus ocellatus. The structure and the relative stereochemistry of the new molecules, which displayed ...
