Among the various forms of programmed cell death implicated in neurodegeneration, necroptosis has recently garnered significant attention. Notably, dysregulated necroptosis provokes immune response that drives excessive pro\u2010inflammatory cytokine production, promoting further necroptotic cell death through TNF\u2010\u03b1\/RIPK1 signaling. Consequently, necroptosis exacerbates neuroinflammation, contributing to the progression of different neurodegenerative diseases. However, the precise role of necroptosis in HD pathogenesis remains unclear. Given the growing interest in repurposing FDA\u2010approved drugs for novel therapeutic interventions, this study investigates the anti\u2010cancer agent Pazopanib (Pazo) as a potential neuroprotective approach for HD. This study assesses Pazo's ability to mitigate necroptosis by targeting the RIPK1\/RIPK3\/MLKL pathway in a model of HD produced by 3\u2010nitropropionic acid (3\u2010NP). Sixty male Wistar rats were randomly assigned to four groups: Group I received normal saline; Group II received Pazo (15\u2009mg\/kg, i.p.); Group III received 3\u2010NP (10\u2009mg\/kg, i.p.); and Group IV received 3\u2010NP (10\u2009mg\/kg, i.p.) and Pazo (15\u2009mg\/kg, i.p.). Behavioral assessments, including open field, rotarod, and wire hanging tests, demonstrated that Pazo significantly improved motor function. At the molecular level, Pazo inhibited PGAM5, a key regulator of mitochondrial fission, effectively reversing the RIPK1\/RIPK3\/MLKL necroptotic cascade and the consequent immune activation. This suppression of necroptosis was associated with reduced microgliosis, neuroinflammation and enhanced neuronal survival within the striatum. These findings highlight the potential of Pazo as a neuroprotective agent against HD by leveraging its antioxidant, anti\u2010inflammatory, immune\u2010modulating, and anti\u2010necroptotic properties.<\/jats:p>","DOI":"10.1002\/ddr.70238","type":"journal-article","created":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T17:00:54Z","timestamp":1769533254000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["From Cancer to Neuroprotection: Pazopanib Modulates the RIPK1\/RIPK3\/MLKL and PGAM5\/DRP1 Pathways in 3\u2010 Nitropropionic Acid\u2010Induced Huntington's Disease"],"prefix":"10.1002","volume":"87","author":[{"given":"Muhammad A.","family":"Eltarzy","sequence":"first","affiliation":[{"name":"Department of Pharmacology and Toxicology, College of Pharmaceutical Sciences and Drug Manufacturing Misr University for Science and Technology (MUST) Giza Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mostafa A.","family":"Rabie","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, Faculty of Pharmacy Cairo University Giza Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rabab H.","family":"Sayed","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Toxicology, Faculty of Pharmacy Cairo University Giza Egypt"},{"name":"Department of Clinical Pharmacy, School of Pharmacy Newgiza University Giza Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maha A.
