Bioxanthracenes from the insect pathogenic fungus. Cordyceps pseudomilitaris BCC 1620. I. Taxonomy, fermentation, isolation and antimalarial activity.

Eleven bioxanthracenes and two monomers, six novel in nature, were isolated from the insect pathogenic fungus Cordyceps pseudomilitaris BCC 1620. Growth optimization of the strain led to the improvement of bioxanthracenes production. The bioxanthracenes were evaluated for their antimalarial activity and cytotoxicity.
