Synthesis and structureâaffinity relationships of 1,3,5-alkylsubstituted cyclohexylamines binding at NMDA receptor PCP site
摘要:
A series of 1,3,5-alkylsubstituted cyclohexylamines 2 were synthesized as ligands for the N-methyl-D-aspartate (NMDA) receptor phencyclidine (PCP) binding site. Pure diastereomers with defined configuration of amino group 2-ax and 2-eq were obtained. The optimal size of 1,3,5-substituents was determined for cyclohexylamines 2 with an equatorial amino group in the lowest energy conformation using Hansch analysis. According to the data, the lipophilic part of cyclohexylamines 2 does not discriminate between hydrophobic regions of the PCP binding site but rather recognizes this site as a whole lipophilic pocket.

Aminocyclohexane and aminoalkylcyclohexane compounds, which are systemic-ally-active as NMDA receptor antagonists, are effective in inhibiting abnormal hyperphosphorylation of microtubule associated protein tau, method of treating disorders resulting from or associated with abnormal hyperphosphorylation of microtubule associated protein tau, and pharmaceutical compositions comprising the same.
The present invention provides methods for treating infections, in a host, by viruses belonging to the Flaviviridae family, such as HCV, comprising administering an Ara-C homologue to the host.
The present invention concerns a new pharmaceutical composition comprising an antagonist and a co-agonist of the N-methyl-D-aspartate-type glutamate receptor (NMDAR). The inventors found that the co-administration of these two compounds effectively inhibits production of amyloide-β peptide. In patient's suffering from Alzheimer's disease, these peptides are deposited in the extracellular matrix forming neuritic "plaques". Therefore, the present inventors identified a new possibility for prophylaxis and/or treatment of Alzheimer's disease by stopping the continued formation of neuropathological extracellular deposits.
The present invention relates to methods of treating various CNS disorders, e.g., mania, bipolar disorder and schizophrenia, by administering NMDA receptor antagonists, alone or in combination with dopamine receptor antagonists.
