The esperamicins represent a class of antitumor antibiotics characterized by an unusual chemical core structure and extremely potent cytotoxicity. The mechanism by which these drugs produce cytotoxicity was investigated and found to be related to the formation of single- and double-strand DNA breaks. Using five structurally related analogs, we defined a structure-activity relationship for cytotoxicity in various eukaryotic and DNA-repair-deficient prokaryotic cell lines, for DNA breakage in a… CONTINUE READING
