Despite advances in immunomodulatory therapies, effective strategies that promote remyelination remain limited. Here, we identify Morusin, a prenylated flavonoid natural compound, as a potent enhancer of oligodendrocyte (OL) differentiation and myelination-associated outcomes. Using a fluorescence-based screen of diverse flavonoids in primary rat oligodendrocyte progenitor cells (OPCs), it was found that Morusin markedly increased myelin basic protein (MBP) expression. To enable cross-species validation, we established a SOX10-inducible human OPC differentiation system, which shortened differentiation time and allowed functional screening in human cells. In this platform, Morusin enhanced OL maturation and induced a transcriptional profile enriched for myelination- and axon ensheathment-related genes, including MBP, PLP1, MAG, and SIRT2. Furthermore, in myelin oligodendrocyte glycoprotein (MOG)35\u201355-induced experimental autoimmune encephalomyelitis (EAE) mice, Morusin improved myelination-associated histological features and functional recovery, comparable to the benchmark compound Benztropine. Collectively, these findings identify Morusin as a promising natural compound with pro-myelinating activity across multiple experimental systems and highlight the potential of rationally guided natural compound screening for regenerative therapy in demyelinating diseases.<\/jats:p>","DOI":"10.3390\/ijms27052311","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T12:39:56Z","timestamp":1772455196000},"page":"2311","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["From Natural Compound Screening to Myelin-Associated Effects: Identification of Morusin as a Potent Promoter of Oligodendrocyte Differentiation"],"prefix":"10.3390","volume":"27","author":[{"given":"Wonjin","family":"Yun","sequence":"first","affiliation":[{"name":"Laboratory of Cell Function Regulation, Department of Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6975-3505","authenticated-orcid":false,"given":"Wonjun","family":"Hong","sequence":"additional","affiliation":[{"name":"Laboratory of Cell Function Regulation, Department of Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyung Taek","family":"Oh","sequence":"additional","affiliation":[{"name":"Laboratory of Cell Function Regulation, Department of Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Hyun","family":"Han","sequence":"additional","affiliation":[{"name":"Institute of Animal Molecular Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyoungmin","family":"Park","sequence":"additional","affiliation":[{"name":"Laboratory of Cell Function Regulation, Department of Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"},{"name":"Institute of Animal Molecular Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7211-5710","authenticated-orcid":false,"given":"In-Yong","family":"Kim","sequence":"additional","affiliation":[{"name":"Institute of Animal Molecular Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Plant Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seungkwon","family":"You","sequence":"additional","affiliation":[{"name":"Laboratory of Cell Function Regulation, Department of Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"},{"name":"Institute of Animal Molecular Biotechnology, College of Life Sciences and Biotechnology, Korea University, Seoul 02841, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2594","DOI":"10.1523\/JNEUROSCI.14-05-02594.1994","article-title":"The role of oligodendrocytes and myelin on axon maturation in the developing rat retinofugal pathway","volume":"14","author":"Colello","year":"1994","journal-title":"J.
