Whereas, the effective components of Prismatomeris connata remains unexplored. The aim of this study was to investigate the inhibitory effects and mechanisms of Rubiadin isolated from Prismatomeris connata against HBV using HepG2.2.15 cells. The levels of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and hepatitis B core antigen (HBcAg) in the supernatants or cytoplasm were examined using by enzyme\u2010linked immunosorbent assay. HBV DNA was qualified q\u2010PCR. Rubiadin was isolated by silica gel column. The structure of the compound was elucidated by HPLC, FT\u2010IR, <jats:sup>1<\/jats:sup>H\u2010NMR, <jats:sup>13<\/jats:sup>C\u2010NMR and identified as 1,3\u2010Dihydroxy\u20102\u2010methyl\u20109, 10\u2010anthraquinone. Rubiadin significantly decreased HBeAg,HBcAg secretion level and inhibit HBV DNA replication. Rubiadin inhibits the proliferation of the cells and HBx protein expression in a dose\u2010dependent manner. The intracellular calcium concentration was significantly reduced. These results demonstrated that Rubiadin could inhibit HepG2.2.15 cells proliferation, reduce the level of HBx expression, and intracellular free calcium, which might become a novel anti\u2010HBV drug candidate.<\/jats:p>","DOI":"10.1002\/ptr.5945","type":"journal-article","created":{"date-parts":[[2017,10,18]],"date-time":"2017-10-18T09:08:35Z","timestamp":1508317715000},"page":"1962-1970","source":"Crossref","is-referenced-by-count":20,"title":["Effects of Rubiadin isolated from Prismatomeris connata on anti\u2010hepatitis B virus activity in vitro"],"prefix":"10.1002","volume":"31","author":[{"given":"Zheng","family":"Peng","sequence":"first","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gang","family":"Fang","sequence":"additional","affiliation":[{"name":"Guangxi University of Chinese Medicine  Nanning 530001 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fenghui","family":"Peng","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiyu","family":"Pan","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengying","family":"Su","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Tian","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danrong","family":"Li","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8712-6367","authenticated-orcid":false,"given":"Huaxin","family":"Hou","sequence":"additional","affiliation":[{"name":"Guangxi Medical University  Nanning 530021 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,10,18]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lfs.2005.09.012"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1086\/656624"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.294.5550.2376"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0168328"},{"issue":"7","key":"e_1_2_8_6_1","first-page":"61","article-title":"Report of cancer incidence and mortality in China, 2010","volume":"2","author":"Chen W.","year":"2014","journal-title":"Annals of Translational Medicine"},{"issue":"3","key":"e_1_2_8_7_1","first-page":"945","article-title":"Emodin, aloe\u2010emodin and rhein induced dna damage and inhibited dna repair gene expression in scc\u20104 human tongue cancer cells","volume":"30","author":"Chen Y.
