Description

3-Methyltoxoflavin is a potent Protein disulfide isomerase (PDI) inhibitor, with an IC50 of 170 nM.

IC50 & Target

IC50: 170 nM (PDI)[1].

In Vitro

3-Methyltoxoflavin is a potent Protein disulfide isomerase (PDI) inhibitor, with an IC50 of 170 nM. 3-Methyltoxoflavin is toxic in a panel of human glioblastoma cell lines. From the screen, 3-Methyltoxoflavin emerges as the most cytotoxic inhibitor of PDI. Bromouridine labeling and sequencing (Bru-seq) of nascent RNA reveals that 3-Methyltoxoflavin induces Nrf2 antioxidant response, ER stress response, and autophagy. Specifically, 3-Methyltoxoflavin upregulates heme oxygenase 1 and SLC7A11 transcription and protein expression and represses PDI target genes such as TXNIP and EGR1. Interestingly, 3-Methyltoxoflavin-induced cell death does not proceed via apoptosis or necrosis, but by a mixture of autophagy and ferroptosis[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 5 mg/mL (24.13 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 5 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 5 mg/mL (24.13 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 5 mg/mL.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

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.
