    Product Description

    Hydroxyurea is an antineoplastic agent that inhibits DNA replication and cell proliferation and induces cell cycle arrest in the G1/S phase.1 It inhibits proliferation of NCI H460 human lung cancer cells in vitro (IC50 = 0.56 mM).2 Hydroxyurea reduces ribonucleoside diphosphate reductase (RNR) activity by 75% when used at a concentration of 5 mM via degradation of its active site tyrosyl radical.1,3 In a humanized mouse model of sickle cell disease (SCD), it reduces leukocyte adhesion and extravasation via NO production and a cGMP-dependent pathway.4 Hydroxyurea also inhibits HIV-1 viral replication in peripheral blood mononuclear cells (PBMCs) in a dose-dependent manner with an IC90 value of 0.4 mM.5,6 Formulations containing hydroxyurea have been used to treat cancer, SCD, and psoriasis.1,7,8
