In Vitro

Deltonin inhibits ERK1/2 and AKT activation. Deltonin (0.5-8 μM) significantly inhibits the proliferation of several colon cancer cell lines including SW480, SW620, LOVO and C26, with IC50s of 1.3, 1.29, 2.11 and 1.22 μM. Deltonin also causes G2-M phase arrest and induces apoptosis in C26 cells[1].
Deltonin (0-5 μM) decreases the phosphorylation of AKT and ERK1/2 levels in MDA-MB-231 cells. Deltonin (0.5-8 μM) also dose-dependently inhibits the proliferation, and causes apoptosis with ROS production in MDA-MB-231 cells[2].

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 (2.82 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 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 (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 (2.82 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]

The cytotoxicity of Deltonin on colon cancer cells is determined by the MTT assay. Cells are seeded at a density of 3 × 103 per well in 96-well plates. After incubation overnight, cells are treated with Deltonin in various concentrations (0.5, 1, 2, 4, 8 μM), and carrier DMSO (< 0.05%) is used as a control, 5 wells are included in each concentration. Every 24 h the absorbance at 570 nm is measured with SpectraMax M5, using wells without cells as blanks. All experiments are performed in triplicate. The concentration-and time-dependent curves of the Deltonin-treated colon cancer cell lines is generated as the % cell growth inhibition, using the following formula: % inhibition = (A570 of control - A570 of treated cells)/A570 of control cells × 100%. The 50% inhibiting concentration (IC50) is calculated[1].

Animal Administration
[1]

Mice[1]
Briefly, 5 × 105 C26 cells are s.c. injected into 4- to 6-wk-old male BALB/c mice. The mice are randomly divided into four groups of 10 mice. One week after C26 implantation, the treatment groups receive their first doses of Deltonin dissolved in a vehicle solution of DMSO (< 0.1%) and diluted in saline solution. Briefly, Deltonin is given via oral administration to tumor-bearing mice at 10, 20 and 40 mg/kg every day for 3 weeks (between day 8 and 28). In parallel, the control group receives the vehicle (DMSO, < 0.1%) in saline solution. The same quantity of saline solution containing DMSO is used in these groups. General clinical observations of the mice, including determination of body weight and tumor growth, are made twice weekly. To determine tumor size, two perpendicular diameters of the tumor in centimeters is measured by calipers. Tumor volume is estimated using the formula 0.52 × a × b2, where “a” is the long diameter and “b” is the short diameter. The mice are sacrificed when they become moribund, and the sacrifice date is recorded to calculate the survival time. To detect the apoptosis protein expression and microvessel density, tumor tissues are removed, fixed in 10% formalin or not and snap-frozen in liquid nitrogen immediately[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.
