Project description:Three new polyoxygenated briarane diterpenoids, briarenols C-E (1-3), were isolated from the octocoral Briareum excavatum. The structures of briaranes 1-3 were elucidated by interpretation of spectroscopic data, and the methylenecyclohexane ring in 1 was found to exist in a twisted boat conformation. Briarenol D (2) displayed an inhibitory effect on the release of elastase by human neutrophils with an IC50 value of 4.65 ?M. Briarenol E (3) was found to inhibit the protein expression of pro-inflammatory inducible nitric oxide synthase (iNOS) in a murine macrophage-like cell line, RAW 264.7, stimulated with lipopolysaccharides (LPS).

Briacavatolides D-F, new briaranes from the Taiwanese octocoral Briareum excavatum.

Project description:In the continued search for novel bioactive substances from the Taiwanese octocoral Briareum excavatum collected at Orchid Island, three new briarane-type diterpenoids, briacavatolides D-F (1-3) were isolated from the acetone extract. The structures of these compounds were elucidated by extensive NMR spectroscopic analysis and physical data. The anti-HCMV (human cytomegalovirus) activity of 1-3 and their cytotoxicity against selected cancer cell lines were evaluated.

Briarenols I-K, New Anti-inflammatory 8,17-Epoxybriaranes from the Octocoral Briareum excavatum (Briareidae).

Project description:Five 8,17-epoxybriaranes, including three new compounds-briarenols I-K (1-3), along with two known analogues, briaexcavatolide P (4) and briaexcavatin P (5), were isolated from the octocoral Briareum excavatum. The structures of briaranes 1-3 were elucidated by spectroscopic methods, including 1D and 2D NMR studies and (+)-HRESIMS. Briarane 4 exerted inhibition effects on inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) release from RAW 264.7.

Proteomics of Candidatus Thiodiazotropha endoloripes, the chemosynthetic symbiont of the lucinid clam Loripes lucinalis from the Bay of Fetovaia

Project description:The Lucinidae is a large family of marine bivalves. They occur in diverse habitats from shallow-water seagrass sediments to deep-sea hydrothermal vents. All members of this family so far investigated host intracellular sulfur-oxidizing symbionts that belong to the Gammaproteobacteria. We recently discovered the capability for nitrogen fixation in draft genomes of the symbionts of Loripes lucinalis from the Bay of Fetovaia, Elba, Italy. With proteomics, we investigated whether the genes for nitrogen fixation are expressed by the symbionts.
