Despite extensive research efforts, currently available pharmacological treatments provide only limited symptomatic relief and do not prevent disease progression. These shortcomings have fuelled growing interest in natural compounds, which possess pleiotropic biological properties and may more effectively target the multifaceted pathology of AD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This systematic review was performed in compliance with the PRISMA 2020 guidelines. Comprehensive literature searches were conducted across PubMed, Scopus, and ScienceDirect to identify preclinical and clinical studies examining the effects of natural compounds in\n                      <jats:italic>in vitro<\/jats:italic>\n                      and\n                      <jats:italic>in vivo<\/jats:italic>\n                      models relevant to AD. Eligible studies assessed phytochemicals, herbal formulations, marine-derived substances, or nutraceuticals and their impact on core AD-related pathological features.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 41 studies fulfilled the inclusion criteria, including 25\n                      <jats:italic>in vivo<\/jats:italic>\n                      and 16\n                      <jats:italic>in vitro<\/jats:italic>\n                      investigations. Across these studies, natural compounds consistently exhibited neuroprotective effects via multiple mechanisms associated with AD pathogenesis. These included the reduction of oxidative stress and neuroinflammation, inhibition of apoptotic pathways, modulation of amyloidogenic processes, attenuation of A\u03b2 aggregation, regulation of tau-associated signalling, and preservation of synaptic function and cognitive outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Overall, the available evidence suggests that natural compounds confer multitarget neuroprotective effects that directly engage with key pathological mechanisms underlying AD. Nonetheless, significant translational challenges remain, particularly with respect to bioavailability, compound standardisation, and clinical efficacy. Further robust, well-controlled clinical trials are essential to establish the therapeutic value of these agents as potential disease-modifying interventions for AD.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fphar.2026.1766470","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T06:30:58Z","timestamp":1771828258000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Natural compounds as multitarget agents in Alzheimer\u2019s diseases: evidence from in vivo and in vitro models"],"prefix":"10.3389","volume":"17","author":[{"given":"Vicko","family":"Suswidiantoro","sequence":"first","affiliation":[{"name":"Doctoral Programme, Faculty of Pharmacy, Universitas Indonesia","place":["Depok, West Java, Indonesia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim San","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Monash University Malaysia","place":["Bandar Sunway, Selangor, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid","family":"Rahman","sequence":"additional","affiliation":[{"name":"Faculty of Science, School of Pharmacy and Biomolecular Sciences, Liverpool John Moores University","place":["Liverpool, United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donna Maretta","family":"Ariestanti","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy, Universitas Indonesia","place":["Depok, West Java, Indonesia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard Johari","family":"James","sequence":"additional","affiliation":[{"name":"Integrative Pharmacogenomics Institute (iPROMISE), UiTM Selangor Branch","place":["Bandar Puncak Alam, Selangor, Malaysia"]},{"name":"Faculty of Pharmacy, UiTM Selangor Branch","place":["Bandar Puncak Alam, Selangor, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Choo Chee","family":"Yan","sequence":"additional","affiliation":[{"name":"Integrative Pharmacogenomics Institute (iPROMISE), UiTM Selangor Branch","place":["Bandar Puncak Alam, Selangor, Malaysia"]},{"name":"Faculty of Pharmacy, UiTM Selangor Branch","place":["Bandar Puncak Alam, Selangor, Malaysia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuyasu","family":"Kato","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy, Universitas Indonesia","place":["Depok, West Java, Indonesia"]},{"name":"Departement of Experimental Pathology, Faculty of Medicine, University of Tsukuba","place":["Tsukuba, Ibaraki, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fadlina Chany","family":"Saputri","sequence":"additional","affiliation":[{"name":"Laboratory of Pharmacology and Toxicology, Faculty of Pharmacy, Universitas Indonesia","place":["Depok, Indonesia"]},{"name":"National Metabolomics Collaborative Research Center, Faculty of Pharmacy, Universitas Indonesia","place":["Depok, West Java, Indonesia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"27","DOI":"10.1007\/s11481-025-10188-4","article-title":"Modulating multiple molecular trajectories by nutraceuticals and\/or physical activity in Attention-Deficit\/Hyperactivity disorder (ADHD)-like behaviors in rat pups","volume":"20","author":"Abu-Elfotuh","year":"2025","journal-title":"J.
