“…695 Reticulolide 745 (Subergorgia reticulata, Sanya Bay, China) was a mono-chlorinated briarane that was isomeric with robustolide A. 696 Pachyclavulides E-I 746-750 were isolated from an Okinawan collection of Pachyclavularia violacea. 697 In the original publication, two representations of 747 were given: perhaps more pertinently the discussion of NOE data observed for 747 included a representation of the diterpene as having an s-cis diene configuration.…”

This review covers the literature published in 2007 for marine natural products, with 948 citations(627 for the period January to December 2007) referring to compounds isolated from marine microorganisms and phytoplankton, green algae, brown algae, red algae, sponges, cnidarians,bryozoans, molluscs, tunicates, echinoderms and true mangrove plants. The emphasis is on new compounds (961 for 2007), together with the relevant biological activities, source organisms and country of origin. Biosynthetic studies, first syntheses, and syntheses that lead to the revision of structures or stereochemistries, have been included.1 Introduction, 2 Reviews, 3 Marine microorganisms and phytoplankton, 4 Green algae, 5 Brown algae, 6 Red algae, 7 Sponges, 8 Cnidarians, 9 Bryozoans, 10 Molluscs, 11 Tunicates (ascidians),12 Echinoderms, 13 Miscellaneous, 14 Conclusion, 15 References.

“…16 In addition to two known briarane diterpenoids, briareins A and B, 17,18 briareins C-L (45-54) have been reported from shallow-water colonies of B. asbestinum. 19 Cyclobutenbriarein A (55), possessing a novel class of C 20 rearranged briarane, was isolated along with five new briarane diterpenes (56)(57)(58)(59)(60). The structures of these metabolites were established on the basis of extensive NMR studies and accurate mass measurements.…”

Diterpenes from gorgonian corals

Covering: 1995 to April 2008. Gorgonian corals continue to provide a wealth of novel structures, many of which exhibit potentially useful biological activity. Notably, the families Briareidae, Gorgoniidae and Plexauridae have been demonstrated to contain a wide variety of natural products including steroids, acetogenins, sesquiterpenes and diterpenes. The most common of the gorgonian natural products are the diterpenes, and the intent of this review is to describe such compounds isolated from gorgonian corals, with a focus on the structures of new compounds as well as their biological activity. There have been developments improving our understanding of the biosynthetic origin of selected diterpenes, and these will also be discussed. This review describes 602 new compounds from 177 articles.

“…In this regard, this study, isolating different calamenene derivatives from S. reticulata, is in agreement with earlier results. Also, several polyoxygenated sterols and briarane-type diterpenoids have already been reported from this gorgonian (Yang, Qi, Zhang, & Li, 2006;Yang et al, 2007).…”

Three aromatic sesquiterpene derivatives, (+)-(7R, 10S)-2-methoxy calamenene (1), (+)-(7R, 10S)-2,5-dimethoxy calamenene (2) and (+)-(7R, 10S)-2-methoxy-5-acetoxy calamenene (3) were isolated from the methanol extract of the Indian gorgonian Subergorgia reticulata. Compound 2 has not been previously described in the literature. Compound 3 has not been isolated previously from a natural source. Compounds 1, 2 and 3 showed settlement inhibition activity against cyprids of Balanus amphitrite with EC(50) values of 4.4, 7.8 and 0.03 µg mL(-1), respectively. These compounds also exhibited considerable activity against Artemia nauplii at 50 µg mL(-1), indicative of their potential use as cytotoxic agents.
