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.

    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

    This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[1]

The analysis of the enzymatic inhibitory capacity of the compound in a panel of 29 protein kinases is developed using a FRET assay based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to protein cleavage (Z′-LYTE Kinase Assay). In the primary reaction, the kinase transfers the γ-phosphate of ATP to a single tyrosine, serine or threonine residue in a synthetic FRET peptide. In the secondary reaction, a site-specific protease recognizes and cleaves non-phosphorylated FRET peptides. Phosphorylation of FRET peptides suppresses cleavage by the development reagent. Cleavage disrupts FRET between the donor (coumarin) and the acceptor (fluorescein) fluorophores on the FRET peptide, whereas uncleaved, phosphorylated FRET peptides maintain FRET. A ratiometric method, which calculates the ratio (the emission ratio) of donor emission to acceptor emission after excitation of the donor fluorophore at 400 n, is used to quantitate reaction progress[1].

Cell Assay
[1]

Cells are treated for 24, 48 and 72 h with the inhibitor or with DMSO as a control. Cell viability is assessed using the colorimetric XTT assay. Cells are seeded in 94-well plates at a density of 4 × 104 cells per well, and allowed to attach for 24 h. The medium is then exchanged with others containing different drug concentrations (0.001−10 μM). Eight wells for each concentration of the CHR-6494 compound are used. At the corresponding time, the culture medium is discharged, the XTT reagent is added and the final cell number and optical density are determined. Dose-response curves are generated and cell viability is evaluated after 72 h of treatment. The half-maximal inhibitory concentration (IC50) is determined using GraphPad Prism software[1].

Animal Administration
[1]

Athymic nu/nu male mice, aged 4-5 weeks, are used for tumor xenograft assays. Animals are maintained in a sterile environment; their cages, food and bedding are sterilized by autoclaving. Mice are anesthetized and tumor cells are injected subcutaneously. In all, 3.5 × 106 exponentially growing HCT-116 cells diluted in 250 μL of sterile PBS are injected subcutaneously in each animal (n = 30). Body weight is recorded and tumor dimensions are measured twice weekly using digital calipers. Tumor volume (in mm3) is estimated according to the formula V = D × d2/2, where D is the long axis and d the short axis of tumor. When tumors reach an average volume of 200 mm3 (15 days after injection), 24 mice harboring homogeneous tumor sizes are randomized into two groups: (1) control group (n = 8) treated with vehicle (solution of 10% DMSO/20% 2-hydroxypropyl-b-cyclodextrin; (2) treatment group (n = 16) mice is diary treated by intraperitoneal injection of 50 mg/kg of CHR-6494 diluted in a solution of 10% DMSO/20% 2-hydroxypropyl-b-cyclodextrin in two cycles of five consecutive days for 15 days. The treatment group is randomly divided into a short-time response group (n = 8), defined by tumor weight at the moment of killing of the control group, and a long-time response group (n = 8), defined by tumor regrowth after treatment. Mice are killed at the end of treatment, and tumors from both groups are excised and weighted. The mean volume of tumor mass is expressed as mean ± s.e.m. for each mouse group, and significance is assessed by means of the Mann-Whitney U-test. Values of P < 0.05 are considered statistically significant. Upon killing mice, colon, lung, liver and kidney tissues are obtained to analyze endogenous toxicity by hematoxylin and eosin[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.
