[CAS NO. 7770-78-7]  (-)-Arctigenin

Arctigenin induces apoptosis in HT-29 colon cancer cells by regulating ROS and p38 MAPK pathways. 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. 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.
