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

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.
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.

Protocolo
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].

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].
