生物活性

Panaxadiol (20(R)-Panaxadiol) is an orally active HIF-1α/STAT3 inhibitor. Panaxadiol can suppress HIF-1α and STAT3 then 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].

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].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

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.

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.43 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。

  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.43 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
