In Vitro

Debio 0932 is an orally active HSP90 inhibitor, with IC50s of 100 and 103 nM for HSP90α and HSP90β, respectively. Debio 0932 (CUDC-305) binds to the tumor HSP90 complex with a mean IC50 of 48.8 nM. Debio 0932 (1 μM) promotes degradation of multiple HSP90 client proteins in cancer cell lines. Debio 0932 also shows inhibitory activities against the proliferation of 40 cancer cell lines (containing 34 solid and 6 hematologic tumor-derived lines) with an IC50 ranging from 40 to 900 nM (mean IC50, 220 nM)[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 (5.65 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 (5.65 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.

Cell Assay
[1]

Human cancer cell lines are plated at 5,000 to 10,000 per well in 96-well plates with culture medium. The cells are then incubated with compounds (Debio 0932) at various concentrations for 120 h. Growth inhibition is assessed by ATP content assay using the ATPlite kit. Briefly, a 25-μL cell lysis solution is added to the 50-μL phenol red-free culture medium per well to lyse cells and stabilize ATP. Then 25-μL substrate solutions are added to the wells, and subsequently, luminescence is measured with a TopCount liquid scintillation analyzer. Values are expressed as a percentage relative to those obtained in untreated controls. IC50 values are calculated using PRISM software with sigmoidal dose-response curve fitting[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration
[1]

When tumors are established after implantation, animals with proper tumor size are randomly assigned into different groups. Debio 0932 is formulated in 30% Captisol and delivered by oral gavage based on the body weight of each individual animal. The control group is treated with vehicle (30% Captisol) using the same dosing paradigm. In combination studies, paclitaxel or camptothecin-11 is diluted in 0.9% normal saline and injected i.p. twice weekly[1].

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.
