Abstract/Description

The octocoral Eunicea fusca is the source of important anti-inflammatory compounds such as the diterpenes fuscol and the fuscosides. Evidence suggests that these compounds are being produce by bacterial sources that live in symbiosis with the coral. As part of an investigation to better understand the role of bacteria associated with E. fusca , the characterization of the bacterial community using two different techniques (culture dependent technique and culture independent technique) and sea...
Show moreThe octocoral Eunicea fusca is the source of important anti-inflammatory compounds such as the diterpenes fuscol and the fuscosides. Evidence suggests that these compounds are being produce by bacterial sources that live in symbiosis with the coral. As part of an investigation to better understand the role of bacteria associated with E. fusca , the characterization of the bacterial community using two different techniques (culture dependent technique and culture independent technique) and sea water samples was done. Sea water samples were used as a control to determine how closely associated bacteria are to this octocoral. The polymerase chain reaction (PCR) with universal bacterial primers FC27 and RC 1492 specific to prokaryotic 16S rDNA gene sequences was used to characterize the total bacterial population when using both the culturable and the non-culturable approaches. The results indicate a diverse group of bacteria associated to E. fusca composed of 10 different groups. The pro teo bacteria group was the most predominant group when both techniques were used. The a-proteobacteria represented the highest percentage of bacteria associated to E. fusca.

Abstract/Description
-
Pseudopterogorgia elisabethae is a known source of structurally interesting bioactive metabolites. A detailed search for new, related compounds was undertaken in this study which resulted in the isolation and characterization of more than ten new diterpenes with serrulatane and ileabethane skeletons. Some of the new compounds isolated are closely related terpenes with significant biological activity and others are likely to be key biosynthetic intermediates. As a component of the development...
Show morePseudopterogorgia elisabethae is a known source of structurally interesting bioactive metabolites. A detailed search for new, related compounds was undertaken in this study which resulted in the isolation and characterization of more than ten new diterpenes with serrulatane and ileabethane skeletons. Some of the new compounds isolated are closely related terpenes with significant biological activity and others are likely to be key biosynthetic intermediates. As a component of the development of a production method of anti-inflammatory compounds such as seco-pseudopterosin and elisabethadione, a synthesis of a seco-pseudoperosin aglycone from elisabethatriene was developed.
