A series of pyrrolobenzodiazepine-naphthalimide conjugates tethered through a piperazine ring system have been designed, synthesized, and evaluated for their anticancer activity. These new conjugates exhibit very high DNA binding affinity and cytotoxic activity against a number of cell lines. (C) 2008 Elsevier Ltd. All rights reserved.
