Here, we aim to investigate its pharmacokinetic behavior and tissue distribution in a mouse model with colitis. Pharmacokinetics and tissue distribution of M10 and its metabolite myricetin were compared in normal mice and in dextran-sodium-sulfate (DSS)-induced colitis mice. The role of fecal microbiota was also analyzed during metabolism of M10 in vitro. After oral administration, M10 was very low in the plasma of both normal and diseased mice. However, both M10 and myricetin were mainly distributed in the gastrointestinal tract, including the stomach, colon and small intestine, in physiological and pathological conditions. Significantly, M10 and myricetin were found in higher levels in gastrointestinal tracts with inflamed tissues than in normal tissues of mice. An in vitro assay revealed that 80% of M10 was metabolized to myricetin via fecal microbiota. After oral administration, M10 was not absorbed into circulation but mainly distributed in the inflamed submucosal tissues of colitic mice, where it was metabolized into myricetin to prevent colitis development.<\/jats:p>","DOI":"10.3390\/molecules27238140","type":"journal-article","created":{"date-parts":[[2022,11,23]],"date-time":"2022-11-23T03:15:24Z","timestamp":1669173324000},"page":"8140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparative Pharmacokinetics and Tissue Distribution of M10 and Its Metabolite Myricetin in Normal and Dextran-Sodium-Sulfate-Induced Colitis Mice"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1223-618X","authenticated-orcid":false,"given":"Jianchun","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Medicine and Pharmacy, Ocean University of China, Qingdao 266003, China"},{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenmin","family":"Yuan","sequence":"additional","affiliation":[{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shixiao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Medicine and Pharmacy, Ocean University of China, Qingdao 266003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8219-6892","authenticated-orcid":false,"given":"Hongwei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Medicine and Pharmacy, Ocean University of China, Qingdao 266003, China"},{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Medicine and Pharmacy, Ocean University of China, Qingdao 266003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaochen","family":"Niu","sequence":"additional","affiliation":[{"name":"School of Medicine and Pharmacy, Ocean University of China, Qingdao 266003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaochun","family":"Liu","sequence":"additional","affiliation":[{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Liu","sequence":"additional","affiliation":[{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiangming","family":"Gao","sequence":"additional","affiliation":[{"name":"Marine Biomedical Research Institute of Qingdao, Qingdao 266073, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1038\/nature06005","article-title":"Unravelling the pathogenesis of inflammatory bowel disease","volume":"448","author":"Xavier","year":"2007","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"465898","DOI":"10.1155\/2010\/465898","article-title":"Anti-TNF-alpha therapies in systemic lupus erythematosus","volume":"2010","author":"Zhu","year":"2010","journal-title":"J.
