It is isolated from the West Indian gorgonian octocoral Pseudopterogorgia elisabethae and exhibits antitubercular and antimalarial activity. It has a role as a metabolite, an antimalarial and an antitubercular agent. It is a terpene lactone, an organic heterotetracyclic compound and a tertiary alcohol."}]
