Panaxadiol (20(R)-Panaxadiol) 是一种具有口服活性的HIF-1α/STAT3抑制剂。Panaxadiol 可以抑制 HIF-1α 和 STAT3,然后导致 programmed cell death-ligand 1 (PD-L1) 表达的下调。Panaxadiol 具有抗癌、保护心脏、抗心律失常和抗氧化的活性。
生物活性 | Panaxadiol (20(R)-Panaxadiol) is an orally activeHIF-1α/STAT3inhibitor. Panaxadiol can suppress HIF-1α andSTAT3then lead to downregulation of programmed cell death-ligand 1 (PD-L1) expression. Panaxadiol shows anticancer, cardioprotective, anti-arrhythmic, and antioxidative activities[1][2]. |
体外研究 (In Vitro) | Panaxadiol (1-10 μM, 12 h) inhibits PD-L1 expression in human colon cancer cells[1]. Panaxadiol (1-10 μM, 12 h) inhibits the expression of PD-L1 by suppressing HIF-1α and STAT3 in HCT116 cells[1].
Western Blot Analysis[1] Cell Line: | HCT116, SW620 and HT-29 colon cancer cells | Concentration: | 1, 3, and 10 μM | Incubation Time: | 12 hours | Result: | Decreased the expression of PD-L1 protein and mRNA in a dose-dependent manner. |
Western Blot Analysis[1] Cell Line: | HCT116 cells | Concentration: | 1, 3, and 10 μM | Incubation Time: | 12 hours | Result: | Inhibited hypoxia-induced nuclear accumulation of HIF-1α in a dose-dependent manner. Inhibited STAT3 phosphorylation at Tyr705 in a dose-dependent manner under both normoxic and hypoxic conditions. |
|
体内研究 (In Vivo) | Panaxadiol (oral gavage; 10 or 30 mg/kg; once every 3 days; 30 d) inhibits the growth of HCT116 cells in a xenograft model[1].
Animal Model: | BALB/c athymic nude mice injected with HCT116 cells[1] | Dosage: | 10 or 30 mg/kg | Administration: | Oral gavage; 10 or 30 mg/kg; once every 3 days; 30 days | Result: | Inhibited the protein levels of HIF-1α, p-STAT-3 (Tyr705), PD-L1 and VEGF in tumour tissues in a dose-dependent manner. |
