Hydroperoxyditerpenoids from Octocorals
Israel Journal of Chemistry, 2019AbstractThe structures, names, bioactivities, and references of 75 marine diterpenoids from octocorals possessing a hydroperoxy group, including 46 cembranes, 8 eunicellins, 5 briaranes, 5 dolabellanes, 4 germacranes, 3 xenicins, 2 caryophyllanes, 1 decalin, and 1 pseudopterosin, are summarized in this review article.

Biology of Deep-Water Octocorals
2011Publisher Summary This chapter discusses the taxonomy, phylogeny, biogeography, ecology, and reproductive biology of deep-sea octocorals and also focuses on gorgonian octocorals because they are the predominant octocoral group in the deep sea.

Four New Steroids from Two Octocorals
Journal of Natural Products, 1999In search of analogues of isogosterones A-D (1-4), a group of antifouling 13,17-seco-steroids found in octocorals of the order Alcyonacea, we have isolated four new steroids possessing aromatic, enone, or dienone A-rings from two octocorals, Alcyonium gracillimum and Dendronephthya sp. These compounds, 3-methoxy-19-norpregna-1,3, 5(10),20-tetraene (5),

The octocorals are colonial cnidarians, many of which contain calcareous spicules in the mesoglea and, in some species, in the axis as well. The octocorals are excellent organisms for probing the mechanisms of biomineralization and demineralization, and the processes of calcification of spicules have been investigated extensively in recent years ...

Cembranoids from the Octocoral Sarcophyton ehrenbergi
Journal of Natural Products, 2010Chemical investigation of the octocoral Sarcophyton ehrenbergi led to the isolation of six new cembranoids, (+)-12-carboxy-11Z-sarcophytoxide (1), (+)-12-methoxycarbonyl-11Z-sarcophine (3), ehrenberoxides A-C (4-6), and lobophynin C (2), along with two known compounds, (+)-sarcophytoxide (7) and (+)-sarcophine (8).

Octocorals of the Indo-Pacific
2019Mesophotic coral ecosystems (MCEs), which comprise the light-dependent communities of corals and other organisms found at depths between 30 and ~150 m, have become a topic that increasingly draws the attention of coral reef researchers. It is well established that after the reef-building scleractinian corals, octocorals are the second most common group

Structural investigations of octocoral sclerites
Zoologica Scripta, 1987A common structural pattern (as observed under the SEM) in the main body of sectioned sclerites of the family Alcyoniidae, and octocorals in general, is the arrangement of acicular crystals in concentric layers. The crystals roughly follow the direction of the spicule axis, however, the sectioned tubercles of large Sinularia spicules have the acicular ...

Steroids from the Antarctic Octocoral Anthomastus bathyproctus
Journal of Natural Products, 2005Seven new steroids, compounds 1-7, were isolated from the Antarctic octocoral Anthomastus bathyproctus. The structures of the new metabolites have been established by analysis of their spectroscopic data. The in vitro cytotoxicity has been tested against three human tumor cell lines.

Further Butenolides from the Caribbean Octocoral Pterogorgia citrina
Journal of Natural Products, 1994Seven fatty acid derivatives containing one or two butenolide moieties along with ancepsenolide [1], a known bis-butenolide of marine origin, were isolated from the Caribbean gorgonian Pterogorgia citrina. The structures of the new metabolites were elucidated on the basis of spectroscopic data and were confirmed upon chemical conversion to either ...
