Isolation and Antifouling Activity of Azulene Derivatives from the Antarctic Gorgonian Acanthogorgia laxa
Three azulenoid sesquiterpenes ( 1 – 3 ) were isolated from the Antarctic gorgonian Acanthogorgia laxa collected by bottom trawls at −343 m. Besides linderazulene ( 1 ), and the known ketolactone 2 , a new brominated C 16 linderazulene derivative ( 3 ) was also identified. This compound has an extra...
