Hydroxyurea suppresses DNA synthesis by inhibiting ribonucleoside diphosphate reductase, which catalyzes the reduction of ribonucleotides to deoxyribonucleotides. Hydroxyurea is used in chronic cases of granulocytic leukemia that are unresponsive to busulfan. In addition, it is used for acute lymphoblastic leukemia. Hydroxyurea may cause bone marrow depression.

Busulfan is a potent cytotoxic drug. Early in development of the compound, in vivo experiments indicated that busulfan caused severe depression in the bone marrow. The most prevalent acute toxic effects associated with busulfan in animals are severe pancytopenia from bone marrow failure. Associated in vivo experiments show bone marrow aplasia, stromal cell damage, immunosuppression (impaired T-lymph-ocyte function), and pronounced adverse effects on reproductive glands, germ cells, and fertility in animals (lowest effective dose tested was 2 mg kg...
