Reaction of the antitumor antibiotic CC-1065 with DNA. Location of the site of thermally induced strand breakage and analysis of DNA sequence specificity

CC-1065 is a unique antitumor antibiotic produced by Streptomyces zelensis. The potent cytotoxic effects of this drug are thought to be due to its ability to form a covalent adduct with DNA through N3 of adenine. Thermal treatment of CC-1065-DNA adducts leads to DNA strand breakage. We have shown th...
