BACKGROUND: Parkinson's disease is a progressive neurodegenerative disorder of the brain, that commonly leads to motor dysfunction and dementia. Artemether is a semi - synthetic derivative of artemisinin, which is extracted from the traditional Chinese herb Artemisia annua. And it is widely used in the treatment of malaria. Recent studies have shown that it exhibits significant neuroprotective effects and holds potential for the treatment of neurodegenerative diseases. However, its effects and mechanisms in the context of Parkinson 's disease remain unclear.
OBJECTIVE: To explore Artemether's neuroprotective effects and mechanisms in 6-OHDA-induced PD models.
METHODS: Network pharmacology and molecular docking were used to predict potential pathways and targets of Artemether against Parkinson's disease. PD models were established using 6-OHDA-induced PC12 cells and C57BL/6 mice to assess Artemether's effects and mechanisms.
RESULTS: Through network pharmacological analysis and molecular docking verification, it was found that Artemether against Parkinson 's disease was related to apoptosis-related signaling pathways, and Artemether had good spontaneous binding activity with key targets PI3K, Akt, GSK-3β, and Bcl-2. Furthermore, the related experimental results showed that Artemether could increase the cell viability of PC12 cells induced by 6-OHDA, reduce intracellular ROS level, increase mitochondrial membrane potential and decrease apoptosis. In addition, Artemether improved motor dysfunction and cognitive dysfunction in Parkinson 's disease mice, and increased the expression of dopamine neurons in both the Substantia Nigra and Striatum.
CONCLUSION: Artemether exerted neuroprotective effects in Parkinson 's disease models in vitro and in vivo induced by 6-OHDA through the PI3K/Akt/GSK-3β signaling pathway.
