Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 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 1 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.

生物活性

製品説明	(-)-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].
