WebJan 17, 2024 · Antitumor antibiotics, agents isolated from strains of Streptomyces, are used for cancer treatment owing to their ability to interfere with DNA and/or RNA synthesis, thus leading to cancer cell death. The effects of these drugs are too toxic for use in bacterial infections. Agents within this class include: Cell cycle –specific: bleomycin WebThe DNA alkylation and sequence specificity of a group of natural and synthetic pyrrolo- [1,4]benzodiazepines [P (1,4)Bs] were evaluated by using an exonuclease III stop assay, and the results were compared with in vitro and in vivo biological potency and antitumor activity.
