Description

CSN5i-3 is a potent, selective and orally available inhibitor of CSN5/Jab1, and inhibits CSN-catalysed Cul1 deneddylation with an IC50 value of 5.8 nM[1].

IC50 & Target

IC50: 5.8 nM (CSN5)[1]
In Vitro

CSN5i-3 traps CRLs in the neddylated state, which leads to inactivation of a subset of CRLs by inducing degradation of their substrate recognition module[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

CSN5i-3 shows a good pharmacokinetic profile. Treatment with CSN5i-3 triggers the formation of cleaved PARP and cleaved caspase 3 indicative of apoptosis induction[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 (4.95 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (4.95 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay

Cell viability is measured using the CellTiter-Glo Assay. Cells (THP-1, HCT116, NCI-H2030 and TE-1) are treated with CSN5i-3 (1 nM, 10 nM, 100 nM, 1 μM, 10 μM) for 72 hours[1].

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

Mice[1]

SU-DHL-1 xenografts were grown in SCID-bg mice and dosed by oral administration with either vehicle control or CSN5i-3 at the indicated doses (50 mg/kg BID, 100mg/kg QD) and schedules (3, 7, 10, 14 day). Tumour response is reported as percentage change in tumour volume at the last day of treatment relative to start of treatment.

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.
