Chang, a synonym of <jats:italic>Hansenia weberbaueriana<\/jats:italic> (Fedde ex H. Wolff) Pimenov &amp;amp; Kljuykov, is an anti-inflammatory medicinal plant. Although abrnotopterol has been reported to be its primary active metabolite, the other metabolites and their mechanisms of action remain unclear. This study aims to investigate the potential mechanisms by which its active metabolites treat Obstructive Sleep Apnea Syndrome (OSAS) through network analysis and experimental assessment.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> The metabolites and potential targets of <jats:italic>Notopterygium incisum<\/jats:italic> were extracted from public databases. We searched for OSAS-related genes in the Genecards, OMIM, PharmGkb, TTD, and DrugBank databases. Cytoscape 3.9.0 was used to construct the drug-target-disease network and screen for hub genes. Human bronchial epithelial (HBE) cells were cultivated in normoxia and chronic intermittent hypoxia (CIH) medium for 24\u00a0h. Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-\u03b1), and prostaglandin E2 (PGE2) were quantified using enzyme-linked immunosorbent assay (ELISA). Prostaglandin-endoperoxide synthase 2(PTGS2) mRNA was detected using RT-qPCR, while PTGS2 and nuclear factor-kappa B (NF-\u03baB) proteins were identified using Western blot analysis. Co-Immunoprecipitation (CoIP) and Western blotting were utilized to evaluate the ubiquitination of PTGS2 in HBE cells.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Pterostilbene and notopterol, isolated from <jats:italic>Notopterygium incisum<\/jats:italic>, had potential therapeutic effects on OSAS. The PTGS2 and estrogen receptor alpha (ESR1) hub genes were associated with OSAS. The pathway enrichment analysis focuses on the NF-\u03baB, apoptosis, and HIF-1A pathways. In response to CIH, pterostilbene and notopterol decreased IL-6, TNF-\u03b1, and PGE2 levels. The NF-\u03baB pathway was activated by an increase in PTGS2 levels. Pterostilbene promoted proteasome-mediated ubiquitination of PTGS2 protein and reduced PTGS2 levels, inhibiting the NF-\u03baB pathway.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> This study reveals the active metabolites of <jats:italic>Notopterygium incisum<\/jats:italic> and hub genes involved in treating OSAS, which provide a basis for the follow-up development and exploitation of the botanical drug.<\/jats:p>","DOI":"10.3389\/fphar.2023.1185100","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T11:21:39Z","timestamp":1693480899000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Active metabolites and potential mechanisms of Notopterygium incisum against obstructive sleep apnea Syndrome (OSAS): network analysis and experimental assessment"],"prefix":"10.3389","volume":"14","author":[{"given":"Peijun","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weihua","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pan","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"122","DOI":"10.1111\/jsr.12485","article-title":"Facial phenotype in obstructive sleep apnea-hypopnea syndrome: a systematic review and meta-analysis","volume":"26","author":"Agha","year":"2017","journal-title":"J.
