Abstract

A new class of unusually potent antitumor drugs modeled after the alkylating antibiotic CC-1065 (isolated from Streptomyces zelensis) are being developed as clinical candidates. Based upon observations of the parent drug a number of novel features have been noted. The drugs bind within the minor groove of DNA in a highly sequence specific manner. A covalent bond is formed with N3 of adenine under proper steric conditions. While the unusually high cytoxicity activity (at
