Deoxosarcophine from a soft coral, sp.
Tetrahedron Letters, 1980Abstract A sample of deoxosarcophine ( 2 ) was converted into sarcophine ( 1 ) by autoxidation. Two reactions are described that will enable the enantiomers of deoxosarcophine to be interrelated.

Microbes in Gorgonian and Soft Corals
2019Corals provide a structurally and environmentally complex array of habitats, supporting a broad microbial diversity that influences both host physiology and ultimately ecosystem processes. Many studies have indicated that microbial communities occupy a range of niches on corals, from within the surface mucus layer to on and within the coral tissue ...

Effects of the soft coral Xenia puertogalerae on the recruitment of scleractinian corals
Journal of Experimental Marine Biology and Ecology, 1996Abstract The effects of Xenia puertogalerae on the recruitment of juvenile corals was studied at two levels, involving early and more advanced settlement stages. Inhibition by X. puertogalerae was evident. Terracotta tiles established near soft coral colonies had fewer recruits than those located away from the soft corals.

Steroid metabolism in Antarctic soft corals
Polar Biology, 1997Whole body tissue preparations of the Antarctic soft corals Alcyonium paessleri and Clavularia frankliniana were incubated in vitro with the radiolabelled precursors 3H-progesterone and 3H-androstenedione to determine steroidogenic capacity. Steroidal metabolites were identified using TLC, derivitization, and recrystallization techniques. The Antarctic

Studies of australian soft corals—XXXV
Tetrahedron, 1985Abstract The in vivo incorporation of mevalonolactone specifically into the terpene portion of a sesquiterpene hydroquinone is reported for the soft coral Sinularia capillosa Eudesma -4 , 7(11)- diene -8β- ol ( 20 ) and the corresponding 8-keto derivative ( 21 ) have been isolated from the soft coral Nephthea species for the first time The ...

Algal overgrowth of alcyonacean soft corals
Marine Biology, 1987Colonies of the soft coral Lobophytum pauciflorum (Ehrenberg, 1834) (Coelenterata: Octocorallia: Alcyonacea: Alcyoniidae), some of which were heavily overgrown by the algae Ceranium flaccidum (Kuetzing) Ardissone and Enteromorpha sp., and other minor epizoites, were collected at Taylor Reef (17°50′S; 146°35′E) in the Great Barrier Reef.

New prostanoids from soft coral
Tetrahedron, 1985Abstract Four new anti-tumor active prostanoids, named claviridenone-a (3), claviridenone-b (4). claviridenone-c (5), and claviridenone-d (6), as well as 20-acetoxy-claviridenone-b (7) and 20-acetoxy-claviridenone-c (8), have been isolated from the Okinawan soft coral (stolonifer) Clavularia viridis Quoy and Gaimard (Stolonifera, Clavulariidae).

Polyhydroxylated steroids from the soft coral
Steroids, 2005A repeated silica gel column chromatography followed by HPLC purification on the methanol extract of marine soft coral Sinularia dissecta, resulted in the isolation of fifteen polyhydroxylated steroids (1-15), involving six new C-18 functionalized steroids, 3beta-acetoxy-1alpha,11alpha-dihydroxygorgost-5-en-18-oic acid (1), gorgost-5-en-1alpha,3beta ...

The structure of a novel nor-cembranoid diterpene of formula C19H24O6 (1) is reported. The compound was extracted from the soft coral Sinularia leptoclados, and spectroscopic data were collected on the parent compound (1) and a series of derivatives. It was not possible to assign an unambiguous structure on purely spectroscopic grounds, and so single ...
