effect of inhibition of spinal cord Glutamate transporters on inflammatory pain induced by formalin and complete freund s adjuvant
Anesthesiology, 2011Co-Authors: Myron Yaster, Xiaowei Guan, Jeffrey D Rothstein, Ronald S Petralia, Wei LuAbstract:Background—Spinal cord Glutamate transporters clear synaptically released Glutamate and maintain normal sensory transmission. However, their ultrastructural localization is unknown. Moreover, whether and how they participate in inflammatory pain has not been carefully studied. Methods—Immunogold labeling with electron microscopy was carried out to characterize synaptic and non-synaptic localization of Glutamate transporters in the superficial dorsal horn. Their expression and uptake activity after formalin- and complete Freund’s adjuvant (CFA)induced inflammation were evaluated by Western blot and Glutamate uptake assays. Effects of intrathecal Glutamate transporter activator [(R)-(−)-5-methyl-1-nicotinoyl-2-pyrazoline], inhibitors [DL-threo-β-benzyloxyaspartate (TBOA), dihydrokainate, and DL-threo-beta-hydroxyaspartate], or TBOA plus a group III metabotropic Glutamate Receptor Antagonist [(RS)-α-methylserine-Ophosphate] on formalin- and CFA-induced inflammatory pain were examined.

Practical, convergent total synthesis of polyamine amide spider toxin NSTX-3
Tetrahedron Letters, 1996Co-Authors: Ian S. Blagbrough, Eduardo Moya, Steven P. WalfordAbstract:Abstract A practical, total synthesis of polyamine amide spider toxin NSTX-3, a potent Glutamate Receptor Antagonist with potential as a neuroprotective agent, is reported. The unsymmetrical polyamine motiety was built by a conjugate addition to afford putreamine and regioselective acylation of L-asparaginyl-cadaverine.

Total synthesis of polyamine amide spider toxin argiotoxin-636 by a practical reductive alkylation strategy
Tetrahedron Letters, 1995Co-Authors: Ian S. Blagbrough, Eduardo MoyaAbstract:Abstract Reductive alkylation is a practical strategy for a total synthesis of spider toxin argiotoxin 636, a polyamine amide which is a selective Glutamate Receptor Antagonist and may have potential as a neuroprotective agent. Central to this synthesis are a Swern oxidation and a reductive alkylation.

Total synthesis of modified jstx toxins: reductive alkylation is a practical route to hexahydropyrimidine polyamine amides
Tetrahedron Letters, 1995Co-Authors: Mark R. Ashton, Eduardo Moya, Ian S. BlagbroughAbstract:Abstract Reductive alkylation is a practical route for a total synthesis of regioisomers of spider toxin JSTX-3, a polyamine amide which is a selective Glutamate Receptor Antagonist and may have potential as a neuroprotective agent. The strategy is based upon a reductive alkylation step which enables one free araine to be generated regiospecifically in the new polyamine, or the regiospecific incorporation of a hexahydropyrimidine moiety which conformationally restricts the polyamine amide backbone.

ampa kainate type Glutamate Receptor Antagonist reduces progressive inner hair cell loss after transient cochlear ischemia
Brain Research, 2003Co-Authors: Nobuhiro Hakuba, Atsushi Matsubara, Jun Hyodo, Masafumi Taniguchi, Toshiki Maetani, Yoshitaka Shimizu, Yuko Tsujiuchi, Masachika Shudou, Kiyofumi GyoAbstract:We investigated the effect of Glutamate Receptor Antagonists on progressive inner hair cell (IHC) loss following transient cochlear ischemia in gerbils. Transient cochlear ischemia was induced by 15-min bilateral vertebral artery occlusion. An alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)/kainate-type Glutamate Receptor Antagonist, 6-7-dinitroquinoxaline-2,3-dione (DNQX), or an N-methyl-D-aspartate (NMDA)-type Receptor Antagonist, MK-801, was administered 10 min before the ischemic insult. Hearing was assessed by sequentially recording compound action potentials (CAPs) before, during, and after the ischemia. The degree of hair cell loss in the organ of Corti was evaluated in specimens stained with rhodamine-phalloidin and Hoechst 33342. On the seventh day after ischemia, the increases in the CAP threshold and the progressive IHC loss were significantly reduced in cochleae treated with DNQX, while MK-801 was ineffective. These results suggest that the AMPA Receptor plays a critical role in the development of the progressive IHC loss induced by ischemia/reperfusion injury in the cochlea.
