However, its therapeutic mechanism remains unclear owing to its complex composition and limited research on its chemical profile.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> We employed a targeted metabolome approach, combining selective reaction monitoring\/multiple response monitoring (SRM\/MRM) with high-performance liquid chromatography and MRM mass spectrometry to quantitatively analyze the flavonoid constituents of <jats:italic>Vernonia anthelmintica<\/jats:italic>. We also used network pharmacology and molecular docking to identify potential vitiligo-linked compounds and targets of <jats:italic>V. anthelmintica<\/jats:italic> seeds. Additionally, we assessed HaCaT cell proliferation by AAPH-induced<jats:bold>,<\/jats:bold> alongside changes in SOD activity and MDA content, following treatment with <jats:italic>V. anthelmintica<\/jats:italic> components. Finally, flow cytometry was used to detect apoptosis and ROS levels.<\/jats:p><jats:p><jats:bold>Results and Discussion:<\/jats:bold> We identified 36 flavonoid compounds in <jats:italic>V. anthelmintica<\/jats:italic> seeds, with 14 compounds exhibiting druggability. <jats:italic>AKT1<\/jats:italic>, <jats:italic>VEGFA<\/jats:italic>, <jats:italic>ESR1<\/jats:italic>, <jats:italic>PTGS2<\/jats:italic>, and <jats:italic>IL2<\/jats:italic> have been identified as key therapeutic target genes, with PI3K\/AKT signaling being an important pathway. Notably, kaempferol, one of the identified compounds, exhibited high expression in network pharmacology analysis. Kaempferol exhibited a strong binding affinity to important targets. Further, kaempferol enhanced HaCaT cell viability, inhibited apoptosis, reduced MDA levels, suppressed ROS activity, and upregulated SOD activity, increase the expression of cellular antioxidant genes, including HO-1, GCLC, GCLM, Nrf2, NQO1 and Keap1, providing significant protection against oxidative stress damage <jats:italic>in vitro<\/jats:italic>. Here, we present the first comprehensive study integrating SRM\/MRM approaches and network analysis to identify active flavonoid compounds within <jats:italic>V. anthelmintica<\/jats:italic> (L.)

Moreover, we revealed that its active ingredient, kaempferol, offers protection against AAPH-induced damage in keratinocytes, highlighting its potential as a clinical resource.<\/jats:p>","DOI":"10.3389\/fphar.2024.1343306","type":"journal-article","created":{"date-parts":[[2024,4,9]],"date-time":"2024-04-09T04:26:53Z","timestamp":1712636813000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Identification of active compounds in Vernonia anthelmintica (L.) willd by targeted metabolome MRM and kaempferol promotes HaCaT cell proliferation and reduces oxidative stress"],"prefix":"10.3389","volume":"15","author":[{"given":"Wen","family":"Hu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongjuan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaixiao","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zixian","family":"Lei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Xiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojing","family":"Kang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"241","DOI":"10.1111\/iji.12432","article-title":"Is the +405 G\/C single nucleotide polymorphism of the vascular endothelial growth factor (VEGF) gene associated with late-onset vitiligo?","volume":"46","author":"Almasi-Nasrabadi","year":"2019","journal-title":"Int.
