Among all, four compounds (10, 12, 16, and 18) showed potent antioxidant activities as well as abilities to minimize AD-related damages (i.e. decreasing intracellular reactive oxygen species (ROS) production, preserving mitochondrial membrane potential (MMP), protecting membrane damage, and modulating beta-secretase 1 (BACE1) activity) with comparable protective effects to the well-known neuroprotectant, resveratrol (RSV). The gene discussed is BACE1; the disease is Alzheimer disease.
