Lignan derivatives and a norditerpene from the seeds of Vitex negundo
Masateru Ono,Yoichiro Nishida,Chikako Masuoka,Jian-Chen Li,Masafumi Okawa,Tsuyoshi Ikeda,Toshihiro Nohara +6 more
TL;DR: Compounds 1, 2, and 4-7 showed higher radical-scavenging effect on the stable free radical, 1,1-diphenyl-2-picrylhydrazyl, than L-cysteine, and showed stronger antioxidative activity than alpha-tocopherol using the ferric thiocyanate method.
Journal ArticleDOI
Cytotoxic Activity of Steroidal Glycosides from Solanum Plants
TL;DR: Among these steroidal glycosides, the spirostanol glycoside having a beta-lycotetraosyl moiety were the most effective against PC-12 and HCT-116 cell lines.
Journal ArticleDOI
Oleanolic acid inhibits macrophage differentiation into the M2 phenotype and glioblastoma cell proliferation by suppressing the activation of STAT3.
Yukio Fujiwara,Yoshihiro Komohara,Rino Kudo,Keiichiro Tsurushima,Koji Ohnishi,Tsuyoshi Ikeda,Motohiro Takeya +6 more
TL;DR: Results indicate that OA suppresses the M2 polarization of macrophages and tumor cell proliferation by inhibiting STAT3 activation, and may be a potentially new agent that can be used for the prevention and treatment of various malignant tumors, including glioma.
Journal ArticleDOI
Anti-obesity compounds in green leaves of Eucommia ulmoides.
Tetsuya Hirata,T. Kobayashi,A. Wada,T. Ueda,T. Fujikawa,T. Fujikawa,Hiroyuki Miyashita,Tsuyoshi Ikeda,Sachiko Tsukamoto,Toshihiro Nohara +9 more
TL;DR: Results suggest that asperuloside in Eucommia leaves has important anti-obesity effects, similar to those of EGLE.
Journal ArticleDOI

Yukio Fujiwara,Ayumi Takaki,Yukie Uehara,Tsuyoshi Ikeda,Masafumi Okawa,Ken Yamauchi,Masateru Ono,Hitoshi Yoshimitsu,Toshihiro Nohara +8 more
TL;DR: In this paper, major novel steroidal alkaloid glycosides, named esculeoside A (1 ) and esculeooside B (2 ), have been isolated from the pink color-type and the red color type, respectively, of the ripe tomato fruits of Lycopersicon esculentum MILL.
