It is isolated from the methanol extract of the whole plant of Chloranthus japonicus and acts as a chitin synthase inhibitor. CJ-01 also shows antifungal activity against various human and phytophathogenic fungi. It has a role as a metabolite, an EC 2.4.1.16 (chitin synthase) inhibitor and an antifungal agent. It is a sesquiterpenoid, an enone, a cyclic ether, an organic heterotricyclic compound, an aromatic ketone and a cyclic terpene ketone."}]
