It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death. Pharmacological alternatives to conventional treatments include alkaloids with anti\u2010inflammatory and antioxidant properties. Sesquiterpene lactones, such as Xanthatin\u201013\u2010(pyrrolidine\u20102\u2010carboxylic acid) (XPc) from burdock leaf, show promise due to their antioxidant activity targeting glucose\u20106\u2010phosphate dehydrogenase. This study evaluated XPc's protective effects in\u00a0vivo using A\u03b2\n                    <jats:sub>25\u201035<\/jats:sub>\n                    \u2010treated mice, a pharmacological AD model, and explores its synergistic potential with neuroprotective agents like TSPO activators or sigma\u20101 receptor agonists.

Behavioral tests assessed memory deficits and anxiety. Post\u2010sacrifice, brains were analyzed for neuroinflammation and oxidative stress markers. Combination studies involved XPc with the TSPO activator PK11195 or the sigma\u20101 receptor agonist PRE\u2010084, with memory evaluated in two behavioral tests. Combination indices were calculated to assess synergy. XPc (1\u20133\u2009mg\/kg) prevented A\u03b2\n                    <jats:sub>25\u201035<\/jats:sub>\n                    \u2010induced memory impairments and anxiety. It reduced astroglial reaction, blocked microglial activation, and confirmed antioxidant activity by lowering lipid peroxidation and protein nitrosylation. Combinations with PK11195 or PRE\u2010084 showed synergistic protection in memory tests. XPc is a potent neuroprotective agent against AD\u2010like toxicity in this murine model, effective alone or in synergistic combinations with other drugs.\n
