A cathepsin K inhibitor, it was first isolated from Paecilomyces carneus and subsequently obtained from Aspergillus nidulans cocultivated with a soil-dwelling actinomycete. It has a role as an EC 3.4.22.38 (cathepsin K) inhibitor and a fungal metabolite. It is a polyketide, a member of phenols and an organic heteropentacyclic compound."}]
