Cell experiment [1]: | |
Cell lines |
DU145 cells |
Preparation method |
The solubility of this compound in DMSO is > 19.7 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition |
25 μM; 18 hrs |
Applications |
Under hypoxic condition, incubation with PX-478 for 18 hrs increased the radiosensitivity of DU145 cells, but did not significantly affect HIF-1α protein level. |
Animal experiment [2]: | |
Animal models |
Nu/nu mice bearing C6 reporter xenografts |
Dosage form |
30 mg/kg; p.o.; for 2 days |
Applications |
In nu/nu mice bearing C6 reporter xenografts, PX-478 treatment (30 mg/kg; p.o.; for 2 days) inhibited the transcriptional activity of HIF-1 in central ischemic regions of C6 tumors. |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

PX-478 2HCl, also called PX-478, is an experimental HIF-1α inhibitor. It inhibited HIF-1α protein at multiple levels in cancer cell lines under normoxia and hypoxia with an IC50 value of ~20-30 μM [1].
Hypoxia-inducible transcription factor HIF-1α activates target genes involved in glycolysis, erythropoiesis and angiogenesis. HIF-1α also regulates the expression of genes coding for apoptotic pathway, growth factors/receptors, cell cycle regulators, metastasis and invasiveness [1].
Under normoxic condition, the IC50 for PX-478 to inhibit HIF-1α in PC3 cells was 20-25 μmol/L, whereas the IC50 for PX-478 to inhibit HIF-1α in the DU 145 cells was ~40-50 μmol/L. in both DU 145 and PC3 cells, 1-hr hypoxia significantly upregulated HIF-1α protein. But the pretreatment with PX-478 for 20 hr under normoxia before 1-hr hypoxia attenuated the accumulation of HIF-1α induced by the 1-hr hypoxia. In PC3 cells, pretreatment with 20 μmol/L PX-478 before hypoxia inhibited HIF-1α by 40% compared to treatment with hypoxia alone. In DU 145 cells, pretreatment with 50 μmol/L PX-478 before hypoxia inhibited HIF-1α by 35% compared to treatment with hypoxia alone [1].
In nu/nu mice with C6 reporter xenografts, treatment with PX-478 at a dose of 30 mg/kg p.o. for 2 consecutive days prevented the transcriptional activity of HIF-1 in central ischemic regions of C6 tumors [2].
