| Description: |
Deferasirox (ICL 670) is an orally available iron chelator used for the management of transfusional iron overload. |
| In Vivo: |
The tumor is significantly smaller in the SIO mice treated with deferasirox compared with control. Mice treated with DFX showed longer survival than the other groups. Deferasirox has a survival benefit for SIO leukemia murine model in terms of iron chelation and antileukemic therapy[3]. |
| In Vitro: |
In LX-2 cells treated with 50 μM deferasirox for 12 h, α1(I)procollagen expression is decreased by 25%, with maximal reductions (10-fold) seen following 24-120 h of treatment. Similarly, α-smooth muscle actin (αSMA) expression is significantly lower[1]. Deferasirox had anti-proliferative effects on HL-60 or KG-1 myeloid leukemia cell lines at a concentration as low as 5 μM . The cytotoxicity is both dose and time dependent[2]. The viability of both EL4 cells and L1210 cells incubated with deferasirox decrease in a concentration-dependent manner[3]. |
| Cell Assay: |
Deferasirox is dissolved in DMSO. HL-60 or KG-1 cells are treated with 0, 5, 10, 50 μM of deferasirox for 24 or 48 h, and proliferation is determined by an MTT assay[2]. |
| Animal Administration: |
Mice: Murine leukemia cells are injected subcutaneously into the right flank of mice. Deferasirox is dissolved in distilled water and orally administered at 20 mg/kg until the cumulative dose reaches 300 mg/kg. The mice are observed and weighed daily[3]. |
