Esperamicin A1 is isolated from the bacterium Actinomadura verrucosospora.  The anthranilate component of esperamicin A1 intercalates DNA and the benzene diradical intermediate of the enediyne core binds to the minor groove of DNA, resulting in single- and double-stranded breaks in DNA and apoptosis.
