Hydroxyurea is a demonstrated antineoplastic agent, which is believed to block DNA replication by inhibiting R1 and R2 (ribonucleotide reductase) via destruction of the free radical at the enzymes active site. Induces apoptosis of in vitro myelogenous leukemia lymphocytes, and the phosphorylation of FADD and p53.
