Adozelesin, also known as U 73975 or adolezesin, is an experimental antitumor drug of the duocarmycin class. Adozelesin is the first of a class of DNA-sequence-selective alkylating agents, the cyclopropa(c)pyrrolo(3,2-e)indol-4(5H)-ones (CPls), that have been shown to have of potent inhibitory properties of DNA synthesis. It binds to and alkylates DNA, resulting in a reduction of both cellular and simian virus 40 (SV40) DNA replication which ultimately reduces the rate of cancer growth. Phase I and Phase II clinical trials were conducted in 2000s, however, it was found adozelesin had marginal efficacy in the treatment of metastatic breast cancer at the dosage and schedule used.
