A synthetic bifunctional quinone derivative with potential antineoplastic activity. Diaziquone alkylates and cross-links DNA during all phases of the cell cycle, resulting in disruption of DNA function, cell cycle arrest, and apoptosis. This agent can also form free radicals, thereby initiating DNA damage via DNA strand breaks. Due to its lipophilicity, diaziquone readily crosses the blood brain barrier. Check for active clinical trials using this agent. (NCI Thesaurus)
