体外研究
(In Vitro)

3-Methyltoxoflavin 是一种有效的蛋白质二硫化物异构酶 (PDI) 抑制剂,IC50 为 170 nM。3-Methyltoxoflavin 在一组人胶质母细胞瘤细胞系中具有毒性。从筛选结果看,3-Methyltoxoflavin 是最具细胞毒性的 PDI 抑制剂。新生 RNA 的溴尿苷标记和测序 (Bru-seq) 显示 3-甲基毒黄素诱导 Nrf2 抗氧化反应、内质网应激反应和自噬。3-Methyltoxoflavin 上调血红素加氧酶 1 和 SLC7A11 转录和蛋白质表达,并抑制 PDI 靶基因,如 TXNIP 和 EGR1。3-甲基毒素黄素诱导的细胞死亡不是通过细胞凋亡或坏死进行的,而是通过自噬和铁死亡的混合作用[1]

动物实验:

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: 5 mg/mL (24.13 mM); 澄清溶液; 超声助溶

    此方案可获得 5 mg/mL的澄清溶液。

    1 mL 工作液为例,取 100 μL 50.0 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% (20% SBE-β-CD in Saline)

    Solubility: 5 mg/mL (24.13 mM); 澄清溶液; 超声助溶

    此方案可获得 5 mg/mL的澄清溶液。

    1 mL 工作液为例,取 100 μL 50.0 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。

    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
[1]

The colon cancer cells are seeded in duplicate in 96-well plates at 7000-10000 cells per well. For the combination therapies, NAC is added to the well at the same time as 3-Methyltoxoflavin (35G8) (24 hours after plates are seeded), and Z-VAD-FMK and Necrostatin-1 are added to the well 1 hour prior to 3-Methyltoxoflavin addition. Cell growth inhibition is assessed by the cell viability rate. Cell viability is determined with the MTT assay. U87MG cells are seeded at 5000 cells per well in 96-well plates. Deferoxamine is added to cells in a five-point, three-fold dilution series from 400 μM. 3-Methyltoxoflavin is added immediately after in a five-point, three-fold dilution series from 100 μM. Cells are incubated with compounds for 12 hours[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.
