In Vitro

NIK SMI1 (Compound 4f) inhibits NIK-catalyzed hydrolysis of ATP to ADP (fluorescence polarization, FP) with an IC50 of 0.23±0.17 nM. NIK SMI1 inhibits the expression of NIK SMI1 response elementregulated firefly luciferase reporter gene in HEK293 cells with an IC50 of 34±6 nM. Consistent with expectations for a NIK inhibitor, NIK SMI1 is shown to inhibit nuclear translocation of p52 (RelB) (IC50=70 nM). NIK SMI1 inhibits BAFF-induced B cell (mouse) survival in vitro with an IC50 of 373±64 nM[1].

In Vivo

C57BL/6 mice are treated twice daily for 7 days with orally administered NIK SMI1 or with three injections of recombinant BAFF receptor fusion protein (Br3- mIgG2a) over the course of the 7-day experiment as a positive control. The nonlinearity of exposure relative to dose between 100 and 200 mg/kg is a result of saturation of clearance mechanisms. The pharmacology of NIK SMI1 is examined in SD rat, CD-1 mouse, beagle, and cynomologous monkey with 20, 32, 18, and 7.8 mL/kg per min, respectively. Volume of distribution (Vd, L/kg) is 1.35, 1.58, 0.778, and 1.39, respectively[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.

Cell Assay
[1]

Human B cells are re-suspended in RPMI with 10% FBS for the proliferation assays and 2.5% FBS for the survival assays. Mouse B cells are plated in Co-star 96-well plates at either 50,000 cells/well for the survival assays or at 150,000 cells/well for the proliferation assays. Compounds (e.g., NIK SMI1) diluted in DMSO (final DMSO assay concentration=0.1%) are added to the cells. The cells are incubated with NIK SMI1 for one hour at 37°C. Stimulus is then added to the plates and survival or proliferation is measured after four days. For the proliferation assays, cells are treated with either Anti-IgM (20 µg/mL) or rhCD40L (10 µg/mL) or anti-mouse CD40 (100 ng/mL). For the BAFF survival assay, cells are treated with human or mouse rBAFF at 10 ng/mL followed by Cell Titer Glo to measure survival on day four[1].

Animal Administration
[1]

Mice[1]
Age-matched C57BL/6 mice are used. Only female mice are used in these experiments. The single oral doses of NIK SMI1 are 10, 20, 60, 100, and 200 mg/kg. For PO dosing, animals are manually restrained, then dosed via oral gavage using an appropriately sized gavage needle. Animals are monitored for any signs of aspiration or distress-respiratory abnormalities, lethargy, pale extremities, etc. For sample collection, 3 mice per group are bled a total of 8 times via tail prick using a 27 G needle (lateral tail vein). 10 μL of blood is collected at each timepoint and deposited into a pre-filled costar cluster tube containing 40 μL of 1.7 mg/mL EDTA/water, the tube is capped, votexed for 5 seconds, then stored on dry ice. Samples are transferred to a -80°C freezer for storage[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.
