Biological Activity
IC50: 0.56 ± 0.043 μM (HIF-1α), 8.46 ± 1.08 μM (DLL4)[1]
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[1].
Steppogenin (0-3 μM, 6 h) suppresses the mRNA expression of HIF-1α target genes (VEGF, GLUT1, CXCR4, and CA9) under hypoxic conditions[1].
Steppogenin (0-3 μM, 16 h) suppresses HIF-1α protein levels, and inhibits protein levels of VEGF, CXCR4, and CA9[1].
Steppogenin (0-3 μM, 24 h) suppresses hypoxia-induced vascular EC proliferation and migration as well as VEGF-induced sprouting of EC spheroids[1].

Cell Line:A549 cells
-
Concentration:0, 0.3, 1, 3 μM
-
Incubation Time:6 h
-

-
Cell 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.
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 T1/2[1].
