Description

WBC100 (14-D-Valine-TPL) is a potent, selective, and orally active c-Myc molecule glue degrader. WBC100 is a c-Myc degrader and targets ubiquitin E3 ligase CHIP mediated 26S proteasome pathway. WBC100 is used for c-Myc overexpressing tumors research[1].

In Vitro

WBC100 selectively kills c-Myc overexpressing cancer cells Mia-paca2, H9, and MOLM-13 cell as well as c-Myc-low normal human cell lines L02, MRC-5 and WI38, the IC50 values are 61 × 10-9, 17 × 10-9, and 16 × 10-9 M for c-Myc overexpressing cancer cells, respectively. Whereas the IC50 values for normal cell lines are 2205 × 10-9, 151 × 10-9, and 570 × 10-9 M, respectively[1].
WBC100 (0-320 nM; 24 hour) decreases c-Myc protein levels in MOLM-13 cells and Mia-paca2 cells in a dose-dependent manner, but has no obvious impact on XPB, Rpb1, and STAT3. Additionally, MG132 can rescue the WBC100-induced decline in c-Myc protein[1].

In Vivo

WBC100 (p.o.; 0.1-0.4 mg/kg; twice daily; 21 days) exerts dose-dependent antitumor activity in vivo. Higher or medium (0.4/0.2 mg/kg) doses of WBC100 eradicates MOLM-13-luciferase cells in vivo and all the mice were disease-free survival on day 35. Additionally, at a low dose (0.1 mg/kg), WBC100 also significantly inhibits tumor growth and prolongs survival of leukemia mice[1].
WBC100 (p.o.; 0.4-0.8 mg/kg; once daily; 14 days) eliminates refractory MOLM-13-luciferase cells in vivo, but both (+)-JQ1 (50 mg/kg, intraperitoneal (i.p.), once a day for 14 d) is ineffective in suppressing tumor growth. WBC100 exhibits stronger antitumor activity than c-Myc transcription inhibitor (+)-JQ1[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 (5.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    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 (5.44 mM); Clear solution; Need ultrasonic

    This protocol yields a clear solution of 2.5 mg/mL.

    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.

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.
