Journal ArticleDOI
Antiproliferative constituents from Umbelliferae plants VII. Active triterpenes and rosmarinic acid from Centella asiatica.
Miyako Yoshida,Masahiro Fuchigami,Tsuneatsu Nagao,Hikaru Okabe,Kazuhisa Matsunaga,Jiro Takata,Yoshiharu Karube,Ryota Tsuchihashi,Junei Kinjo,Kunihide Mihashi,Toshihiro Fujioka +10 more
TL;DR: The antiproliferative constituents in the MeOH extract from the aerial parts of Centella asiatica were investigated and anti-cancer activity of the isolated compounds against human gastric adenocarcinoma, uterine carcinoma, and murine melanoma cells was estimated.
Journal ArticleDOI
Interactions of Phytoestrogens with Estrogen Receptors α and β (III). Estrogenic Activities of Soy Isoflavone Aglycones and Their Metabolites Isolated from Human Urine
Junei Kinjo,Ryota Tsuchihashi,Keiko Morito,Toshiharu Hirose,Tohru Aomori,Tsuneatsu Nagao,Hikaru Okabe,Toshihiro Nohara,Yukito Masamune +8 more
TL;DR: In this paper, the effect on the estrogen-dependent growth of MCF-7 cells, binding ability to human estrogen receptors (hERs) alpha and beta, and effect on hERdependent beta-galactosidase induction, of these isoflavone metabolites were examined.
Journal ArticleDOI
Anti-herpes virus type 1 activity of oleanane-type triterpenoids.
Tsuyoshi Ikeda,Kazumi Yokomizo,Masafumi Okawa,Ryota Tsuchihashi,Junei Kinjo,Toshihiro Nohara,Masaru Uyeda +6 more
TL;DR: The anti-herpes simplex virus type 1 (HSV-1) activity of 15 oleanan-type triterpenoides including glycyrrhizin and its sapogenol was examined and their structure-activity relationships were discussed.
Journal ArticleDOI
Hepatoprotective constituents in plants. 14. Effects of soyasapogenol B, sophoradiol, and their glucuronides on the cytotoxicity of tert-butyl hydroperoxide to HepG2 cells.
Junei Kinjo,Tomoki Hirakawa,Ryota Tsuchihashi,Tsuneatsu Nagao,Masafumi Okawa,Toshihiro Nohara,Hikaru Okabe +6 more
TL;DR: The results were considerably different from those reported previously on the protective effects of these compounds using primary cultures of immunologically injured rat liver cells, Consequently, the hepatoprotective action of the triterpene derivatives investigated would be different in HepG2 cells and in rat primary hepatocyte cultures.
Journal ArticleDOI
Development of an enzyme-linked immunosorbent assay (ELISA) using highly-specific monoclonal antibodies against plumbagin
Seiichi Sakamoto,Waraporn Putalun,Ryota Tsuchihashi,Satoshi Morimoto,Junei Kinjo,Hiroyuki Tanaka +5 more
TL;DR: The monoclonal antibody against PL which is secreted from established hybridoma cell line3A3 (MAb 3A3) has been proven to have highly-specific to PL resulting from cross-reactivities test.
