It has been found to exhibit moderate cytotoxicity against several human tumour cell lines via specific apotopic cell death. It also displays anti-HIV, antibacterial, antifungal and antimalarial activity. It has a role as a metabolite, an antineoplastic agent, an antibacterial agent, an antifungal agent, an antimalarial and an anti-HIV agent. It is a member of phenols, an organobromine compound, a tertiary alcohol, a diterpenoid and a macrolide."}]
