生物活性

Eriodictyol is a flavonoid isolated from the Chinese herb, with antioxidant and anti-inflammatory activity. Eriodictyol induces Nrf2 signaling pathway. Eriodictyol is also a potent influenza RNA-dependent RNA polymerase inhibitor with an IC50 of 18 nM.

IC50 & Target

Nrf2[1]

体外研究
(In Vitro)

Eriodictyol is a flavonoid isolated from the Chinese herb, with antioxidant and anti-inflammatory activity[1]. Eriodictyol (20, 40, 80 μM) protects primary cultured cortical neurons against Aβ25-35-induced cytotoxicity and cell apoptosis via the Nrf2/ARE pathway. Eriodictyol (80 μM) induces nuclear expression of Nrf2 and the expression of ARE-regulated genes in primary cultured cortical neurons[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Eriodictyol shows protective effect against LPS-induced acute lung injury (ALI). Eriodictyol (30 mg/kg, p.o.) decreases the production of inflammatory cytokines, elevates survival rate, and decreases oxidative stress levels in LPS-induced ALI mice. Eriodictyol inhibits MPO activity and inflammatory neutrophil accumulation in the lung tissues. Eriodictyol treatment also enhances Trx1 expression by upregulating the Nrf2 expression in lung tissues[1].

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: ≥ 2.58 mg/mL (8.95 mM); 澄清溶液

    此方案可获得 ≥ 2.58 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.8 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.58 mg/mL (8.95 mM); 澄清溶液

    此方案可获得 ≥ 2.58 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.8 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Cell Assay
[2]

Primary cultures of cortical neurons are prepared from day 17 Sprague-Dawley rat embryos and maintained in Neurobasal A medium supplemented with B27. Experiments are performed 7 days after seeding. Aβ25-35 is dissolved in deionized distilled water at a concentration of 1 mM and incubated at 37°C for 7 days to induce its aggregation. Eriodictyol is added at indicated concentrations (20, 40, 80 μM) 2 h prior to Aβ25-35 treatment. Eriodictyol is dissolved in dimethyl sulfoxide (DMSO) at 64 mM as stock solution and diluted in culture medium before use[2].

Animal Administration
[1]

Mice[1]
Eighty female C57BL/6 mice are anesthetized by an intraperitoneal injection of 150 mg/kg ketamine HCl and 65 µg/kg xylazine hydrochloride. E. coli LPS is instilled intratracheally (25 µg in 50 µL sterile saline) during inspiration. The control mice receive PBS instillation, while the Eriodictyol- and vehicle-treated mice receive Eriodictyol (30 mg/kg, dissolved in PBS) and vehicle (PBS), respectively, orally 2 days prior to the induction of ALI. The mice are then sacrificed by an intravenous injection of thiopental 24 h after the induction of ALI. The thorax is opened and the blood is sampled by cardiac puncture. Simultaneously, three bronchoalveolar lavage (BAL) procedures are performed, each using 0.5 mL normal saline. The blood is centrifuged (2,000 × g, for 10 min at 4°C) and the serum is stored for further processing; the survival curve is then depicted using the Kaplan-Meier method[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
