Isolated from fungal fermentation broth of Chaetomium globosum, it exhibits inhibitory activity against chemokine receptor CCR-5. It has a role as a chemokine receptor 5 antagonist and a Chaetomium metabolite. It is a carbobicyclic compound, an enol, a tertiary alcohol, a carboxylic ester, a member of pyrrolidin-2-ones and a member of octahydronaphthalenes. It is functionally related to a sch 210972."}]
