Description

Formononetin is a potent FGFR2 inhibitor with an IC50 of ~4.31 μM. Formononetin potently inhibits angiogenesis and tumor growth[1].

IC50 & Target[1]

FGFR2

4.31 μM (IC50)

In Vitro

Formononetin is one of the major isoflavonoid constituents isolated from Astragalus membranaceus and has been demonstrated diverse pharmacological benefits. Formononetin possesses anti-angiogenic activity in human colon cancer cells. Formononetin also promotes cell cycle arrest via downregulation of Akt/Cyclin D1/CDK4 in human prostate cancer cells[1].
Formononetin (25 to 150 μM) markedly decreases the proliferation of endothelial cells stimulated by FGF2[1].

Cell Viability Assay[1]

Cell Line: HUVECs
Concentration: 0, 10, 25, 50, 75, 100, and 150 μM
Incubation Time:
Result: Significantly decreased the proliferation of HUVECs stimulated by FGF2 in a dose-dependent manner, while had little inhibitory effects on HUVECs that were not stimulated by FGF2.
In Vivo

Formononetin dramatically suppresses tumor volumes and the Formononetin-treated group tumor weight are significantly inhibited compared with the vehicle group . Formononetin treatment is well tolerated, and there is no significant difference in weight between vehicle group and formononetin treated groups[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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (9.32 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 (9.32 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 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.

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.
