Chem."],"abstract":"<jats:p>The Chinese medicinal plant <jats:italic>Thesium chinense<\/jats:italic> Turcz. is the only plant used in the manufacture of Bairui Granules. However, to date, there has been very little research into the cytotoxic activity of active substances derived from Bairui Granules. Using chemical separation and spectroscopic methods, phenolic compounds 1\u20135 were identified as methyl-<jats:italic>p<\/jats:italic>-hydroxycinnamate, vanillin, kaempferol, isorhamnetin-3-<jats:italic>O<\/jats:italic>-glucoside, and astragalin, respectively. UPLC-MS\/MS analyses revealed that compounds 1\u20135 were present at concentrations of 0.006 \u00b1 0.002, 1.63 \u00b1 0.87, 3.65 \u00b1 0.83, 26.97 \u00b1 11.41, and 27.67 \u00b1 2.91\u00a0<jats:italic>\u03bc<\/jats:italic>g\/g, respectively in Bairui Granules. Compounds 1, 2, and 4 were detected here for the first time in Bairui Granules. Using co-culture experiments, isorhamnetin-3-<jats:italic>O<\/jats:italic>-glucoside (4) was found to be beneficial to the proliferation Chinese hamster ovary (CHO) cells (6.46% \u00b1 0.86% to 38.45% \u00b1 9.04%), natural killer cells from human umbilical cord blood (UCB NK cells) (25.68% \u00b1 0.02% to 70.81% \u00b1 0.26%), and mesenchymal stem cells from human umbilical cord blood (UCB MSC cells) (1.66% \u00b1 0.05% to 27.64% \u00b1 0.51%) when the concentration was similar to that found in Bairui granules. Moreover, vanillin (2) was conducive to UCB NK cells proliferation (28.21% \u00b1 0.44%) at a concentration of 64\u00a0<jats:italic>\u03bc<\/jats:italic>g\/mL, while maintaining cell viability. UCB NK cell proliferation was promoted at rates of 41.03% \u00b1 0.48% to 67.22% \u00b1 0.68% when astragalin (5) was present at low concentrations (8 and 16\u00a0<jats:italic>\u03bc<\/jats:italic>g\/mL). Methyl-<jats:italic>p<\/jats:italic>-hydroxycinnamate (1) and vanillin (2) at different concentrations both had an inhibitory effect on the proliferation of natural killer cells from human peripheral blood (PB NK cells), but the inhibitory concentration ranges of these compounds were not equivalent to the concentration ranges of the compounds in Bairui Granules. These results provide a foundation for the safe use of <jats:italic>T. chinense<\/jats:italic> preparations.<\/jats:p>","DOI":"10.3389\/fchem.2024.1506792","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T04:23:38Z","timestamp":1733113418000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Cytotoxic activity of phenolic compounds in Bairui Granules obtained from the Chinese medicinal plant Thesium chinense"],"prefix":"10.3389","volume":"12","author":[{"given":"Shaobin","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Hua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shihong","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,12,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1007\/s13596-020-00531-w","article-title":"Vanillin: a review on the therapeutic prospects of a popular flavouring molecule","volume":"21","author":"Arya","year":"2021","journal-title":"Adv.
