    Description

    Visomitin (SKQ1) is a mitochondrial-targeted antioxidant with the high mitochondrion membrane penetrating ability and potent antioxidant capability[1].

    In Vitro

    Direct treatment of tumor infiltrating leukocytes with Visomitin (SkQ1) does not influence their cytotoxicity against Panc02 cells. While Visomitin does not affect viability of the cell lines, this drug at 500 nM concentration reduces heavily the proliferation of human PDAC cells[1].

    In Vivo

    Regarding systemic angiogenic factors, it is observed in serum of Pancreatic ductal adenocarcinoma (PDAC) bearing mice a decrease in KC in the group of continuous treatment with Visomitin (SkQ1). Treatment of the mice with Visomitin increases the level of VEGF molecules. The amount of MIP1a and prolactin is reduced in all Visomitin treatment groups or after the follow-up treatment, respectively. Also, an increase in the IL-6 and IL-13 amount is found in the Visomitin treated groups. TGF-b amount is decreased in the pretreatment setting. On the contrary, all schemes of the Visomitin treatment decrease the NKT cell percentage. The Visomitin treatment has prolonged the median survival of PDAC-bearing mice, but the difference does not reach the level of significance defined[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: ≥ 2.5 mg/mL (4.05 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 (4.05 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      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.

    Cell Assay
    [1]

    Panc02 cells are treated 48 h with different concentrations of Visomitin (SkQ1). Cell viability after Visomitin treatment is measured with an EZ4U Kit as described by the manufacturers. Briefly, 20,000 cells per well are seeded in 96-wellplates and let grow overnight. Afterwards, cells are treated without the medium exchange. A substrate compound from the kit is added and the cells are further incubated for 5 hr at 37°C to convert the yellow colored tetrazolium to its red formazan derivate by living cells. The absorbance is measured at 450 nm[1].

    Animal Administration
    [2]

    Female C57BL/6 mice are used in this study. For experiments on both acute and chronic pancreatitis, mice are divided in three groups. Group A (acute pancreatitis (AP) n=8; chronic pancreatitis (CP) n=12) is treated with 5 nmol/kg Visomitin (SkQ1), group B (AP n=8; CP n=12) is the untreated control, and group C (AP n=8; CP n=7) is the sham group, which is injected intraperitoneally with 0.9% NaCl instead of cerulein and is therefore the negative control group without pancreatitis. For experiments on acute pancreatitis, mice are pretreated with Visomitin for 8 weeks prior to induction of pancreatitis. Mice designated for experiments on chronic pancreatitis receive Visomitin at the same concentration for 8 weeks in parallel with induction of pancreatitis[2].

    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.
