生物活性
Echinomycin (Quinomycin A) 是一種有效的,細胞滲透性的低氧誘導因子-1 (HIF-1) DNA 結合活性的小分子抑制劑。Echinomycin 選擇性抑制癌癥干細胞，其 IC50 值為 29.4 pM。體外研究
Echinomycin (0-10 nM; 16 hours; U251 cells) treatment significantly inhibits hypoxia-induced VEGF mRNA expression in a dose-dependent fashion. Echinomycin very potently inhibits hypoxic induction of luciferase expression in U251-HRE in a dose-dependent fashion with an EC 50 of 1.2 nM.
RT-PCR
| Cell Line: | U251 cells |
| Concentration: | 0 nM, 0.625 nM, 1.25 nM, 5 nM, 10 nM |
| Incubation Time: | 16 hours |
| Result: | Significantly inhibited VEGF mRNA expression induced by hypoxia in a dose-dependent fashion. |
體內(nèi)研究
Echinomycin (10 μg/kg; intravenous injection; for 40 days; NOD-SCID mice) treatment efficiently eradicates mouse lymphoma and serially transplantable human acute myeloid leukemia (AML) in xenogeneic model by preferential elimination of cancer stem cells (CSCs). HIF1α maintains mouse lymphoma CSCs by repressing a negative feedback loop in the Notch pathway.
| Animal Model: | NOD-SCID mice received 1.8Gy of irradiation and i.v. injection with peripheral blood cells from patients AML-71 and AML-150 |
| Dosage: | 10 μg/kg |
| Administration: | Intravenous injection; for 40 days |
| Result: | Efficiently eradicated mouse lymphoma and serially transplantable human AML in xenogeneic model by preferential elimination of CSCs. |
