Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.7mg/ml Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 74 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% corn oil
1.85mg/ml Taking the 1 mL working solution as an example, add 50 μL of 37 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description (-)-Arctigenin, a lignan found in certain plants of the Asteraceae, exerts biological activities including anti-inflammatory, antiviral and anticancer.
In vitro Arctigenin induces apoptosis in HT-29 colon cancer cells by regulating ROS and p38 MAPK pathways[1]. It is a phytoestrogen that exerts a proliferative effect by binding to the ER. Treatment with arctigenin effectively downregulates ERα expression. Thus, arctigenin, mainly targets the mTOR pathway in ERα-positive MCF-7 human breast cancer cells, leading to autophagy-induced cell death and the downregulation of ERα expression[2]. Arctigenin decreases BACE1 translation via dephosphorylation of eIF2α, causing the suppression of Aβ production, and initiates autophagy through both AMPK/Raptor signaling activation and AKT/mTOR pathway inhibition, resulting in enhanced Aβ clearance. Arctigenin suppresses BACE1 activity via inhibition of BACE1 translation[3].
In vivo Treatment of arctigenin in mice highly decreases Aβ formation and senile plaques and efficiently ameliorates AD mouse memory impairment of APP/PS1 transgenic model mice[3].

Protocol (from reference)

Cell Assay:[3]
  • Cell lines

    HEK293-APPswe, primary cortical neuronal, and BV2 cells

  • Concentrations

    0.1, 1, 10, 20, 40 μM

  • Incubation Time

    24 h

  • Method

    Cells are treated with 0.1% DMSO or different concentrations of arctigenin for 24 h. The cell culture media are collected, and a complete protease inhibitor mixture is added. The culture media are then centrifuged by 20,000 × g at 4°C for 30 min, and supernatants are collected.

Animal Study:[3]
  • Animal Models

    The APP/PS1 mice

  • Dosages

    3 mg/kg/d

  • Administration
