Trigonelline is an alkaloid with potential antidiabetic activity that can be isolated from Trigonella foenum-graecum L or Leonurus artemisia. Trigonelline is a potent Nrf2 inhibitor that blocks Nrf2-dependent proteasome activity, thereby enhancing apoptosis in pancreatic cancer cells. Trigonelline also has anti-HSV-1, antibacterial, and antifungal activity and induces ferroptosis.

In Vitro

Trigonelline (TG) significantly rescues the morphology of the H9c2 cells. Treatment of cells with Trigonelline attenuates H2O2 induced cell deaths and improves the antioxidant activity. In addition, Trigonelline regulates the apoptotic gene caspase-3, caspase-9 and anti-apoptotic gene Bcl-2, Bcl-XL during H2O2 induced oxidative stress in H9c2 cells. For evident, flow cytometer results also confirms that Trigonelline significantly reduces the H2O2 induced necrosis and apoptosis in H9c2 cells[1].

In Vivo

Trigonelline decreases bone mineralization and tends to worsen bone mechanical properties in streptozotocin-induced diabetic rats. In nicotinamide/streptozotocin-treated rats, Trigonelline significantly increases bone mineral density (BMD) and tends to improve cancellous bone strength. Trigonelline differentially affects the skeletal system of rats with streptozotocin-induced metabolic disorders, intensifying the osteoporotic changes in streptozotocin-treated rats and favorably affecting bones in the non-hyperglycemic (nicotinamide/streptozotocin-treated) rats[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: ≥ 0.71 mg/mL (5.18 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.71 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 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: ≥ 0.71 mg/mL (5.18 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.71 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (7.1 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

The H9c2 cells are seeded in the 96 well at a density of 1×105 cells/well. The cells are treated with different concentrations of Trigonelline (TG) (25 to 150 μM) and hydrogen peroxide (25 to 125 μM). It is incubated at 37°C in 5% CO2 incubator for 24 h and 6 h respectively and then the culture is treated with the water soluble tetrazolium (WST) reagent incubated for 2 h to 4 h. The living cells absorb the WST then it is converted into an orange colour product. Then, the intensity of colour is measured at 450 nm using spectra count ELISA reader. For cardio protective activity, the cells are seeded and separated into six groups control, H2O2 alone, the rest of groups’ initially exposed to different concentration (25 to 125 μM) of Trigonelline for 48 hours. Then, 100 μM of H2O2 is added and incubated for 4 hours, after, read the absorbance at 450 nm for cell viability assay[1].

Animal Administration
[2]

Three-month-old female Wistar rats are used in this study. The animals are divided into five groups (n=10): Control rats, Streptozotocin-treated control rats, Streptozotocin-treated rats receiving Trigonelline (50 mg/kg p.o. daily), Nicotinamide/streptozotocin-treated control rats, and Nicotinamide/streptozotocin-treated rats receiving Trigonelline (50 mg/kg p.o. daily). Administration of Trigonelline starts two weeks after streptozotocin and lasts four weeks. Trigonelline is administered once daily by a stomach tube. All control rats receive tap water (the vehicle) at the same volume of 2 mL/kg p.o. The four-week period of Trigonelline administration is long enough to demonstrate skeletal effects of Trigonelline and other compounds of plant origin in rats. The rats are fasted overnight after the last Trigonelline or vehicle administration. The next day, the blood glucose level is measured and the rats are anesthetized with ketamine and xylazine, and then sacrificed by cardiac exsanguination[2].

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.
