    Tolebrutinib purchased from MedChemExpress. Usage Cited in: Nat Commun. 2025 Sep 26;16(1):8477.  [Abstract]

    Quantification of MBP+ staining area, respectively (n = 3 MS hiPSC-lines; at least 30 glia-enriched organoids analyzed per experimental condition, respectively). The violin plots show the median (red line), quartiles (dotted lines), as well as the minima and maxima; each dot corresponds to one glia-enriched organoid. The results showed that Tolebrutinib (1 μM; 18 h) was able to rescue CSF-induced oligodendrocyte toxicity (MBP+ staining area ANOVA p < 0.0001).

    Tolebrutinib purchased from MedChemExpress. Usage Cited in: J Leukoc Biol. 2024 Jul 8:qiae160.  [Abstract]

    BTK inhibitors (evobrutinib, fenebrutinib, and Tolebrutinib) at concentrations of 1 µM or 10 µM or solvent control (0.01% DMSO). Afterward, neutrophils were activated with fMLF (1 nM) or CXCL8 (30 ng/mL) for 3 min. Cells were then fixed and microscopically scored as resting (round) or activated (blebbed/elongated) and the percentage activated cells of total cells was calculated. Next, the percentage inhibition of the treatments compared with DMSO control was calculated from the percentage activation.

    Tolebrutinib purchased from MedChemExpress. Usage Cited in: J Leukoc Biol. 2024 Jul 8:qiae160.  [Abstract]

    Purified neutrophils from healthy donors (n = 6) were treated with BTK inhibitors (evobrutinib, fenebrutinib, or Tolebrutinib) at concentrations of 0.1 µM, 1 µM, or 10 µM. Calcein AM (1 µM) and EthD-1 (0.5 µM) were added to visualize live and dead cells, respectively. DMSO (0.1%) and buffer were used as vehicle and negative control. The cells were imaged for 5 hours in the Incucyte imaging system and the percentage of dead cells (EthD-1+) was calculated.

    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 (5.49 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 (5.49 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.

    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.
