CC-1065 transformations.

Abstract
This report defines the transformations that antitumor antibiotic CC-1065 underwent under basic and acidic conditions. The isolation, purification, characterization and biological properties of a cyclopropapyrroloindole fragment and an acidic fragment, PDE-I dimer, from a mild alkaline fragmentation and the phenolic product, AAP, resulting from alkylation of acetic acid by the cyclopropyl function are described.
