Journal Article
Metabolism of methylenedioxymethamphetamine: formation of dihydroxymethamphetamine and a quinone identified as its glutathione adduct.
TL;DR: Results indicate that MDMA is oxidized by cytochrome P-450 to the catechol and the ctcholamine oxidization by superoxide to a quinone to which GSH or other thiol functions add.
Journal ArticleDOI
Behavioral evidence for a modulating role of σ ligands in memory processes. I. Attenuation of dizocilpine (MK-801)-induced amnesia
Tangui Maurice,Masayuki Hiramatsu,Jiro Itoh,Tsutomu Kameyama,Takaaki Hasegawa,Toshitaka Nabeshima +5 more
TL;DR: The results suggest that the potentiating effect of sigma ligands on NMDA receptor-mediated glutamatergic neurotransmission, already demonstrated electrophysiologically, may have some relevance to learning and memory processes in the hippocampus.
Journal ArticleDOI
Comparison of the behavioral and biochemical effects of the NMDA receptor antagonists, MK-801 and phencyclidine
TL;DR: The results suggest that the behavioral responses induced by MK-801 involve primarily the PCP receptor and the dopamine system, and that the differences from PCP reflect a reduced effect on the 5-HT neuronal system.
Journal ArticleDOI
Silibinin prevents amyloid β peptide-induced memory impairment and oxidative stress in mice
Ping Lu,Ping Lu,Takayoshi Mamiya,Lingling Lu,Lingling Lu,Akihiro Mouri,Li Bo Zou,Taku Nagai,Masayuki Hiramatsu,Takashi Ikejima,Toshitaka Nabeshima +10 more
TL;DR: The effect of silibinin on the memory impairment and accumulation of oxidative stress induced by Aβ25–35 in mice is examined.
Journal ArticleDOI
Role of nitric oxide and cyclic GMP in the dizocilpine-induced impairment of spontaneous alternation behavior in mice.
Kiyofumi Yamada,Masayuki Hiramatsu,Yukihiro Noda,Takayoshi Mamiya,Masaaki Murai,T. Kameyama,Yumiko Komori,Toshiaki Nikai,Hisayoshi Sugihara,Toshitaka Nabeshima +9 more
TL;DR: The results suggest that the reduction in nitric oxide/cyclic GMP production in the brain may be responsible for dizocilpine-induced impairment of spontaneous alternation behavior in a Y-maze.
