  • Lethally irradiated C57BL/6 recipient mice were injected with a 1:1 mixture of GFP+JAK2(V671F) and wild-type bone marrow cells. Five weeks later, mice were treated with vehicle (C), hydroxyurea (H; 30 mg/kg twice daily IP), ruxolitinib (R; 30 mg/kg twice daily oral gavage), BMN673 (B; 0.33 mg/kg IV), H+R, H+B, R+B, and H+R+B for 3 weeks. Percentage of GFP+JAK2(V617F) was measured in (panel B) bone marrow cells, (panel C) splenocytes, and (panel D) peripheral blood leukocytes; (panel E) number of GFP+JAK2(V617F) Lin−Sca1+c-Kit+ (LSK) cells per 106 bone marrow cells was calculated, too. *P < .05, **P < .05, and ***P < .05 when compared with control, single treatment, and double treatment, respectively, from 6 to 7 mice using the Student t test.

    Cultured HCC827, H1650, and A549 cells were treated with DMSO and dynasore (50 μM) for 24 h or hydroxyurea (HU, 200 μM) for 12 h before lysed. Protein samples were analyzed by immunoblotting with indicated antibodies.

Biological Activity

Description Hydroxyurea is an antineoplastic agent that inhibits DNA synthesis through the inhibition of ribonucleoside diphosphate reductase.
ribonucleoside diphosphate reductase [1]
In vitro

hydroxyurea can inhibit HIV-1 replication. In vitro experiments have shown that the 90% inhibitory concentration (IC90) of hydroxyurea for laboratory strains of HIV-1 in activated PBMC is 0.4 mM. Hydroxyurea was also found to be synergistic with the nucleoside reverse transcriptase inhibitor didanosine and to inhibit HIV-1 replication in activated PBMC; this inhibition may be due to a reduction in deoxynucleoside triphosphate pool sizes. Hydroxyurea has been shown to sensitize didanosine-resistant mutants[1][2].hydroxyurea has demonstrated activity in the treatment of sickle cell anemia by increasing the production of fetal hemoglobin, which reduces hemolysis in patients with this disease. Hydroxyurea exerts its cytostatic effect through inhibition of ribonucleotide reductase—the rate-limiting enzyme responsible for the conversion of ribonucleotides to deoxyribonucleotides, which are essential for DNA synthesis. As a result, cellular division is arrested in the S phase[1].

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
