Steppogenin 产品活性：Steppogenin 是一种有效的 HIF-1α 和 DLL4 的抑制剂，其 IC50 值分别为 0.56 和 8.46 μM。Steppogenin 可用于血管生成疾病的研究，如实体瘤。 产品来源： https://www.medchemexpress.cn/steppogenin.html 研究领域：Metabolic Enzyme/Protease 作用靶点：HIF/HIF Prolyl-Hydroxylase 来源：植物 | 桑科 | 柘 结构分类：黄酮类 | 黄酮 | 结构分类 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. 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 T1/2.
