2. Nitrosureas-that inhibit a cancer cell's enzymes needed for DNA repair. Carmustine and Lomustine are examples of Nitrosureas.
3. Antimetabolites-that interfere with both a cancer cell's DNA and RNA. 5-Fluorouracil, Methotrexate and Fludarabine are examples of Antimetabolites.
4. Antitumor Antibiotics-that also interfere with a cancer cell's DNA in addition to changing its cellular membrane-the outside layer of protective coating. Bleomycin, Doxorubicin and Idarubicin are examples of Antitumor Antibiotics; and,
5. And Mitotic Inhibitors-which are plant alkaloids that inhibit enzymes
needed for protein synthesis in the cancer cell. Docetaxel, Etoposide and
Vinorelbine are examples of Mitotic Inhibitors.
