Herbacetin is a natural flavonoid from flaxseed, exerts various pharmacological activities, including antioxidant, anti-inflammatory and anticancer effects. Herbacetin is an Ornithine decarboxylase (ODC) allosteric inhibitor, directly binds to Asp44, Asp243, and Glu384 on ODC. Ornithine decarboxylase (ODC) is a rate-limiting enzyme in the first step of polyamine biosynthesis.

Description

Herbacetin is a natural flavonoid from flaxseed, exerts various pharmacological activities, including antioxidant, anti-inflammatory and anticancer effects[1]. Herbacetin is an Ornithine decarboxylase (ODC) allosteric inhibitor, directly binds to Asp44, Asp243, and Glu384 on ODC. Ornithine decarboxylase (ODC) is a rate-limiting enzyme in the first step of polyamine biosynthesis[2].

IC50 & Target

IC50: Ornithine decarboxylase[2]

In Vivo

Herbacetin (orally administration; 20mg/kg) significantly reduces the body weight, plasma glucose, plasma insulin, and HOMA-IR activity in obesity associated insulin resistant mice (OIR). (Herbacetin dissolves in 0.5% DMSO)[1].
Herbacetin (intraperitoneal injection; 0.4, 2, 10 or 20 mg/kg; B.W.) decreases the number and size of polyps in APCMin+ mice with no overt toxicity[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 (8.27 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 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 (8.27 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.

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.
