Abstract

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive impairment and pathological accumulation of amyloid-β and tau proteins. This study investigated the potential neuroprotective effects of a combined treatment consisting of artemisinin, N-acetylcysteine, resveratrol, and hesperidin in a streptozotocin (STZ)-induced intracerebroventricular (ICV) rat model of AD. Twenty 8-week-old rats were divided into four groups: control, SHAM, STZ-ICV, and STZ-ICV receiving oral administration of the compound combination for 30 days. Cognitive performance was evaluated using the Morris water maze and passive avoidance tests. Neurodegenerative and molecular changes were assessed through Western blot analysis of phosphorylated tau, amyloid-β-related markers, and apoptosis- and inflammation-associated proteins. Histological analyses included Nissl staining and immunofluorescence for amyloid deposition and caspase-3 expression. Results demonstrated that STZ-ICV administration induced significant cognitive impairment, neuronal loss, and increased amyloid-β and phosphorylated tau levels. Treatment with the combined compounds partially improved behavioral performance and was associated with reductions in amyloid-β deposition, tau phosphorylation, and caspase-3 expression, along with improved neuronal preservation in the hippocampus. These findings suggest that the combined administration of artemisinin, N-acetylcysteine, resveratrol, and hesperidin exerts multi-target neuroprotective effects in an experimental AD model, potentially through modulation of oxidative stress, neuroinflammation, and apoptotic pathways. However, further studies are required to evaluate pharmacokinetics, safety, and translational relevance before clinical application.
