Biological Activity

Description Deferiprone is a chelating agent with an affinity for ferric ion (iron III),binds with ferric ions to form neutral 3:1 (deferiprone:iron) complexes that are stable over a wide range of pH values.
Features Possesses 10-fold higher cytotoxicity than maltol in both HL-60 and HSC-2 cell lines.
In vitro

Deferiprone (100 μM) is able to protect myocytes from doxorubicin-induced lactate dehydrogenase release. Deferiprone (300 μM) quickly and efficiently removes iron(III) from its complex with doxorubicin. Deferiprone (300 μM) rapidly enters myocytes and displaces iron from a fluorescence-quenched trapped intracellular iron-calcein complex, suggesting that in the myocyte, deferiprone should also be able to displace iron from its complex with doxorubicin. Deferiprone (3 mM) also greatly reduces hydroxyl radical production by the iron(III)-doxorubicin complex in the xanthine oxidase/xanthine superoxide generating system. [1] Deferiprone (0.5 mM) increases removal of RBC membrane free iron in a time and dose dependent manner. [2] Deferiprone (0.3 mM) is effective in inhibiting radioactive iron mobilization from iron-loaded heart cells and protecting or restoring mitochondrial respiratory enzyme activity. Deferiprone (1 mM) results in a sharp decrease in complex I-III activity in iron-loaded heart cells. [3] Deferiprone shows cytotoxic effect of human tumor cell lines HSC-2, HSC-3 and HL-60 with IC50 of 13.5 μg/mL, 9.9 μg/mL and 10.6 μg/mL, the cytotoxic activity of HK1 against HL-60 and HSC-2 cells is reduced in the presence of FeCl3. Deferiprone (100 μg/mL) induces internucleosomal DNA fragmentation in HL-60 cells, but the addition of FeCl3 inhibits the DNA fragmentation. Deferiprone (100 μg/mL) activates the caspase 3, 8 and 9 in HSC-2 cells. [4]

In vivo Deferiprone (100 mg/kg) reduces the mean basilar artery cross-sectional areas by 24% in rabbits. Deferiprone (100 mg/kg) combined with subarachnoid hemorrhage(SAH) shows a variable amount of corrugation of the internal elastic lamina in rabbits. [5]

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 (g) = Concentration (mol/L) × Volume (L) × 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.
