Product Description | Steppogenin is a potent inhibitor of HIF-1α and DLL4 , with IC 50 values of 0.56 and 8.46 μM, respectively. Steppogenin can be sued for the research of angiogenic diseases, such as those involving solid tumors In Vitro Steppogenin (0-10 μM, 24 h) inhibit the transcriptional activity of HIF-1α under hypoxic conditions in HEK293T cells and VEGF-induced DLL4 expression in vascular endothelial cells (ECs) in a dose-dependent manner. Steppogenin (0-3 μM, 6 h) suppresses the mRNA expression of HIF-1α target genes (VEGF, GLUT1, CXCR4, and CA9) under hypoxic conditions. Steppogenin (0-3 μM, 16 h) suppresses HIF-1α protein levels, and inhibits protein levels of VEGF, CXCR4, and CA9. Steppogenin (0-3 μM, 24 h) suppresses hypoxia-induced vascular EC proliferation and migration as well as VEGF-induced sprouting of EC spheroids. MCE has not independently confirmed the accuracy of these methods. They are for reference only. RT-PCRCell Line: A549 cells Concentration: 0, 0.3, 1, 3 μM Incubation Time: 6 h Result: Suppressed the mRNA expression of HIF-1α target genes (VEGF, GLUT1, CXCR4, and CA9) under hypoxic conditions. Western Blot AnalysisCell Line: HEK293T, A549, ARPE19 cells Concentration: 0, 0.3, 1, 3 μM Incubation Time: 16 h Result: Significantly suppressed HIF-1α protein levels in a dose-dependent manner. reduced nuclear expression of HIF-1α under hypoxic conditions. Inhibited protein levels of VEGF, CXCR4, and CA9 compared with the levels detected in the vehicle control group. Suppresseed VEGF-induced DLL4 protein expression. In Vivo Steppogenin (2 mg/kg, IP, once) inhibits tumor growth and angiogenesis . Steppogenin (2 mg/kg, IP, once) shows the highest distribution to the liver and spleen (25.5-fold and 9.74-fold AUC ratio, respectively) with significantly higher T 1/2 .
