High-affinity iodine- and ethyl-C-5 substituted analogs of 4-hydroxy-3-(3-[11C]methoxyphenyl)-2(1H)-quinolone ([11C]4HQ) were synthesized as new positron emission tomography radioligands for the glycine-binding sites of the N-methyl-d-aspartate (NMDA) ion channel. Although both radioligands showed high in vitro specific binding to rat brain slices, their(More)
In August 2009, Miyazaki Health and Welfare Network (Haniwa Net, hereafter referred to as “the Net”), centrally led by University of Miyazaki Hospital (UMH), adopted a center hospital-based system offering a unilateral linkage that enables the viewing of UMH’s medical records through a web-based browser (electronic medical records (EMR)). By the end of(More)
Two new (11)C-labelled ligands, N-(3-(4-hydroxyphenyl)propyl)-3-(4-methoxyphenyl)propylamine ([(11)C]2) and N-(3-(4-hydroxyphenyl)butyl)-3-(4-methoxyphenyl)butylamine ([(11)C]3) were designed based on bis(phenylalkyl)amines (1) which have been reported as polyamine site antagonists with high-selectivity for NR1A/2B NMDA receptors, and radiolabelling of the(More)
NPS 1506 [3-fluoro-gamma-(3-fluorophenyl)-N-methylbenzenepropamine] is representative of a non-psychotomimetic class of N-methyl-D-aspartate (NMDA) receptor antagonists. [11C]NPS 1506 was prepared at high radiochemical purity (>98%) with a specific activity of around 50 GBq/micromol at the end of synthesis by methylation of the desmethyl precursor with(More)
