Isolated from the culture broth of Chrysosporium merdarium, it acts as an inhibitor of HIV-1 protease and EGF-R protein tyrosine kinase. It has a role as a metabolite, a HIV protease inhibitor and an epidermal growth factor receptor antagonist. It is a bisindole alkaloid, an enol and a member of dihydroxy-1,4-benzoquinones."}]
