Dna-binding indole derivatives, their prodrugs and immunoconjugates as anticancer agents

摘要

The present invention relates to novel DNA alkylating agents and the prodrugs of these agents which are useful as antitumor agents and DNA labelling agents. The compounds are hydroxy dihydrobenzindole oligopeptides and prodrugs thereof wherein the monomeric constituents are derived from monocyclic or bicyclic heterocyclic aromatic residues.
