Alzheimer's disease (AD) is a major neurological disease affecting elder people worldwide. Existing drugs only reduce the symptoms of the disease. Commonly, Aβ25-35 peptide aggregation is the main reason for AD development. Recently, the discovery of multiple protein-targeting molecules is a new strategy for AD treatment. This study demonstrates the neuroprotective potential of oxymatrine against multiple mechanisms like acetylcholinesterase, mitochondrial damage, and β-amyloid induced cell toxicity. The in vitro cell culture studies showed that oxymatrine possesses signi cant potential in the inhibition of the Acetylcholine esterase enzyme. Treatment of oxymatrine enhanced the antioxidant, antiapoptotic, and Aβ25-35 peptide aggregation prevention mechanism in PC12 cells. Furthermore, oxymatrine has the competence to protect the PC12 cells against Aβ25-35 induced cytotoxicity and down-regulates the ROS generation. The in vivo acute toxicological studies con rmed that the oxymatrine did not induce any organ damage or death in test animal groups. Overall, the study evidenced that, oxymatrine as an e cient neuroprotective agent, might be a multifunctional drug for Alzheimer's disease treatment. We believed that this is a reliable and synergistic approach to Alzheimer's treatment strategy.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
