Abstract

The invention provides therapeutically effective compounds for the prevention and treatment of cancer and pharmaceutical compositions containing these compounds as well as methods of using and administering these compounds. The invention also includes methods of activating a prodrug of these therapeutically effective compounds by the administration of a peptide-directed targeting construct that delivers a prodrug-activating enzyme to a target activation site.
