    Description

    Sulfasalazine (NSC 667219) is an anti-rheumatic agent for the research of rheumatoid arthritis and ulcerative colitis. Sulfasalazine can suppress NF-κB activity. Sulfasalazine is a type 1 ferroptosis inducer[1][2][3][4].

    Autophagy

     

    In Vitro

    Treatment of SW620 colon cells with sulfasalazine inhibits TNFα-, LPS-, or phorbol ester-induced NFκB activation. NFκB-dependent transcription is inhibited by sulfasalazine at micro- to millimolar concentrations. TNFα-induced nuclear translocation of NFκB is prevented by sulfasalazine through inhibition of IκBα degradation[1]. Pre-incubation with 5 mM of sulfasalazine alone significantly increases basal mRNA expression of all pro-inflammatory cytokines with levels of IL-6 mRNA increased by 80-fold compared with vehicle control[2]. Once digested, sulfasalazine is cleaved into sulfapyridine and 5-aminosalicylic acid by colonic bacteria, and the latter, too, is reported to suppress NF-kappaB activity[3].

    In Vivo

    At low doses (0.25 mM), SAS is able to suppress glioma growth by over 60% compared to untreated controls[3].

    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: ≥ 2.5 mg/mL (6.28 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (6.28 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    Cell Assay
    [1]

    Sulfasalazine is dissolved in culture medium. SW620 cells are grown in Dulbecco’s modified Eagle medium, supplemented with 10% heat-inactivated FCS, 2 mmol/liter glutamine, and 1% (wt/vol) penicillin/streptomycin. SW620 cells are transfected with the 3xIgkBLuc reporter construct. After 18 h, cells are incubated with either medium alone or with sulfasalazine (0.1, 0.2, 0.5, 1, 2, 5 mM) before stimulation with TNFα, LPS, or PMA. Luciferase assay is performed[1].

    Animal Administration
    [3]

    Mice: Sulfasalazine is dissolved in 0.1 M NaOH, and then neutralized by titrating with 0.1 M HCl. U-87MG glioma cells are implanted into the cranium of a SCID mouse. After 7 days, animals are randomized into three groups of five animals each. One group receives 1 mL i.p. saline injections twice daily for 3 weeks. The two test groups receives 8 mg of sulfasalazine in 1 mL saline twice daily for 3 weeks. Tumor growth and animal health were monitored. After perfusion with 4% paraformaldehyde, mouse brains were collected, rinsed, and placed in 30% sucrose[3].

    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.
