Glycogen synthase kinase-3 beta (GSK-3\u03b2) also plays a role in AD through abnormal activation. In this study, the potential of \u03b2-arbutin to inhibit cholinesterases and GSK-3\u03b2 was investigated, utilizing in vitro assays, cytotoxicity analysis, and molecular docking simulations to explore its therapeutic implications.\nMaterials and methods: Ellman\u2019s technique was used to test the inhibitory effects of arbutin on cholinesterase enzymes. An ATP-Glo luminescent assay kit was used to evaluate the inhibitory effects and inhibition kinetics of arbutin on GSK-3\u03b2. A Cell Titer-Glo 2.0 assay kit was used to assess the cytotoxicity of arbutin in SH-SY5Y cells.\nResults: \u03b2-Arbutin exhibited significant inhibitory effects on AChE, BuChE, and GSK-3\u03b2, with IC50 values of 0.6, 4, and 1.23 \u03bcM, respectively. The inhibition kinetics of GSK-3\u03b2 with respect to ATP was competitive but with respect to the substrate (GS-2) was noncompetitive. We further found that \u03b2-arbutin, when applied alone to SH-SY5Y cells, does not affect cell viability and can ensure the sustainability of cell viability and health. Docking scores were \u22127.980, \u22126.726, and \u22126.115 kcal\/mol for GSK-3\u03b2, AChE, and BuChE, respectively.\nConclusion: Our research demonstrates that arbutin is a modulator of cholinesterase and GSK-3\u03b2 and may be beneficial as a multitargetdirected therapeutic natural compound for AD.<\/jats:p>","DOI":"10.55730\/1300-0152.2972","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T16:54:39Z","timestamp":1787072079000},"page":"286-295","source":"Crossref","is-referenced-by-count":0,"title":["Profiling arbutin as a potent cholinesterase and GSK-3\u03b2 inhibitor and evaluating its cytotoxicity in SH-SY5Y cells for Alzheimer\u2019s disease therapy"],"prefix":"10.55730","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7931-1546","authenticated-orcid":true,"given":"SHIRIN","family":"TARBIAT","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2100-285X","authenticated-orcid":true,"given":"TU\u011eBA","family":"BAL","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2427-3863","authenticated-orcid":true,"given":"DEN\u0130Z","family":"G\u00dcLMEZ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34691","published-online":{"date-parts":[[2026,8,14]]},"container-title":["Turkish Journal of Biology"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,26]],"date-time":"2026-10-26T09:51:41Z","timestamp":1793008301000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.tubitak.gov.tr\/biology\/vol50\/iss4\/4"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,14]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026,8,14]]}},"URL":"https:\/\/doi.org\/10.55730\/1300-0152.2972","relation":{},"ISSN":["1300-0152"],"issn-type":[{"value":"1300-0152","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,14]]}}}
