Description

Tectorigenin is a plant isoflavonoid originally isolated from the dried flower of Pueraria lobate Benth.

In Vitro

Tectorigenin is a plant isoflavonoid originally isolated from the dried flower of Pueraria thomsonii Benth. Palmitic acid (PA)-stimulated ROS production is abolished by treatment with Tectorigenin for HUVECs in a dose-dependent manner (0.1, 1, 10 μM). Treatment with Tectorigenin attenuates enhanced IKKβ phosphorylation and effectively blocks NF-κB activation by inhibition of p65 phosphorylation at concentrations ranging from 0.1 to 10 μM. Tectorigenin treatment also effectively inhibits PA-augmented TNF-α and IL-6 production in a concentration dependent manner[1]. The number of viable HepG2 cells treated by Tectorigenin decreases in a concentration- and time-dependent manner. When HepG2 cells are treated with Tectorigenin at 5, 10 and 20 mg/L for 24 h, the viability rate is 91%, 79% and 62%, respectively[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: ≥ 2.08 mg/mL (6.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (6.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Kinase Assay
[1]

HUVECs grown to confluence in 24-well plates are pretreated with Tectorigenin (0.1, 1, 10 μM), salicylate (5 mM) or GSH (1 mM) for 30 min, then stimulated with Palmitic acid (PA) (100 μM) for further 12 h in serum-free medium, and the medium is then collected on ice. The levels of TNF-α and IL-6 in the supernatant are assayed with commercial ELISA Kits[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay
[2]

Cell viability is assessed by MTT method. Briefly, cells are seeded in 96-well plate at a density of 1×104 cells/well. After 24 h incubation, Tectorigenin at different concentrations is added to the cells while only DMSO (solvent) is added as a negative control. After growing for 12, 24 and 48 h, cells are incubated with MTT (0.5 mg/mL) for 4 h at 37°C. During this incubation period, water-insoluble formazan crystals are formed, which are dissolved by the addition of 100 μL/well DMSO. The optical densities at 570 nm are measured using an enzyme-linked immunosorbent assay plate reader. Wells containing culture medium and MTT but no cells act as blanks[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.
