Konakhin, a novel type of degraded sesterterpene; isolation from a marine sponge of Senegal
Abstract
An unidentified sponge collected off Konakhè, near Dakar, contains a novel type of degraded linear sesterterpene, konakhin (+)-1, formally deriving from the replacement by chlorine of the carbonyl carbon in the tetronic moiety of fasciculatin (–)-2, the main terpene of this sponge.
