Biological Activity

Description Deferiprone (CP20) 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
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
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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
