Abstract/Description
-
9,11-secogorgosterol is a secondary metabolite from the gorgonian Pseudopterogorgia americana which acts as a chemical defense. The soft coral lives in a symbiotic association with unicellular algae known as zooxanthellae. A biosynthetic investigation, using in vivo and in vitro methods, has resulted in the identification of the metabolic precursor of 9,11-secogorgosterol as gorgosterol. This finding is significant as it indicates that the conversion of gorgosterol to 9,11-secogorgosterol is...
Show more9,11-secogorgosterol is a secondary metabolite from the gorgonian Pseudopterogorgia americana which acts as a chemical defense. The soft coral lives in a symbiotic association with unicellular algae known as zooxanthellae. A biosynthetic investigation, using in vivo and in vitro methods, has resulted in the identification of the metabolic precursor of 9,11-secogorgosterol as gorgosterol. This finding is significant as it indicates that the conversion of gorgosterol to 9,11-secogorgosterol is due to gorgonian metabolism. Since gorgosterol is known to be a product of zooxanthellae metabolism, this would be the first example of a defensive secondary metabolite being produced by two organisms living in symbiosis. A viable acetone powder has been generated from the crude cell-free extract and has demonstrated the efficient transformation of gorgosterol to 9, 11-secogorgosterol. This indicates possible future value as a synthetic tool for secosterol production.
