    Description

    CB-5083 is a first-in-class, potent, selective, and orally bioavailable inhibitor of the p97 AAA ATPase/VCP. CB-5083 selectively inhibits p97 through its D2 site with the IC50 of 11 nM[1].

    IC50 & Target

    IC50: 11 nM (p97)[1]

    In Vitro

    CB-5083 shows cell killing potency with IC50s of 0.68, 0.68, 1.03, and 0.49 μM for lung carcinoma A549 CTG, A549 K48, A549 CHOP, and A549 p62, respectively[1].

    In Vivo

    CB-5083 (75 mg/kg; oral administration; qd; for 2 weeks) shows antitumor activity in an HCT 116 tumor xenograft model[1].
    CB-5083 exhibits terminal elimination half-life (T1/2=2.56 h), moderate oral bioavailability (mouse 41%) and Cmax (mouse 7.95 μM) following oral administration (25 mg/kg) in female nude mice[1].
    CB-5083 exhibits terminal elimination half-life (T1/2=2.83 h) due to high plasma clearance (5.9 mL/min/kg respectively) combined with large volumes of distribution (418 mL/kg respectively) following intravenous administration (3.0 mg/kg) in female nude mice[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 (6.05 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 (6.05 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 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.

    • Protocol 1

      Add each solvent one by one:  50% PEG300    50% Saline

      Solubility: 10 mg/mL (24.19 mM); Clear solution; Need ultrasonic

    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.
