生物活性

Echinomycin (Quinomycin A) is potent small-molecule and cell-permeable inhibitor of hypoxia-inducible factor-1 (HIF-1) DNA-binding activity. Echinomycin selectively inhibits the cancer stem cells (CSCs) with an IC₅₀ of 29.4 pM.

体外研究

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 EC₅₀ 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.

体内研究

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.
