Abstract
Cytorhodin S derivatives, especially cytorhodin S-immunoglobulin complexes are disclosed. Cytorhodin S possesses very high anticancer activity, but the complexes act more selectively on cancer cells and are more useful as an anticancer agent. New intermediate derivatives are also useful as an anticancer agent.
