Abstract
N-Methyl-d-aspartate (NMDA) receptors are fundamental for the normal function of the central nervous system (CNS), and play an important role in memory and learning. Over-activation of these receptors leads to neuronal loss associated with major neurological disorders such as Parkinson's disease, Alzheimer's disease, schizophrenia, and epilepsy. In this study, 22 novel enantiopure bicyclic lactams were designed, synthesized, and evaluated as NMDA receptor antagonists. Most of the new compounds displayed NMDA receptor antagonism, and the most promising compound showed an IC50 value on the same order of magnitude as that of memantine, an NMDA receptor antagonist in clinical use for the treatment of Alzheimer's disease. Further biological evaluation indicated that this compound is brain permeable (determined by an in vitro assay) and non-hepatotoxic. All these results indicate that (3S,7aS)-7a-(4-chlorophenyl)-3-(4-hydroxybenzyl)tetrahydropyrrolo[2,1-b]oxazol-5(6H)-one (compound 5 b) is a potential candidate for the treatment of pathologies associated with the over-activation of NMDA receptors.

Abstract
CuH-catalyzed enantioselective conjugate reduction of 3,3-diaryl-substituted acrylonitriles is described. A range of 3-aryl-3-pyridylacrylonitriles were reduced with high levels of enantioselectivity under optimal conditions employing a copper/Josiphos complex in the presence of polymethylhydrosiloxane (PMHS).

Abstract
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 [11C]methyl iodide in the presence of NaH. Biodistribution of [11C]NPS 1506 in mice and rat demonstrated that uptake into the brain was rapid and occurred at high levels. [11C]NPS 1506 showed no appreciable specific binding in rodent brains under in vivo conditions, possibly because of both a large non-specific bound fraction and low in vitro binding affinity for NMDA receptors.
