Abstract: A method is disclosed for the treatment of neuropsychopharmacological disorders which are associated with or result from excessive activation of the N-methyl-D-aspartate receptor complex, which method comprises administering an effective neuropsychopharmacological disorder-treating amount of a compound possessing partial agonist properties for the strychnine insensitive glycine modulatory sites of N-methyl-D-aspartate receptors. Exemplary of partial agonists which are useful in the method of the invention are 1-aminocyclopropanecarboxylic acid, and associated derivates thereof. Novel injectable pharmaceutical compositions are also disclosed.

Abstract: The use of a compound possessing functional antagonist properties at the NMDA receptor complex through a specific action at the associated strychnine-insensitive glycine site to improve cognition in normal humans and to treat cognitive deficits resulting from chronic neuronal degeneration, acute brain injury, hypoxia, or other neurological disorders is provided. The compounds possessing functional antagonist properties comprise 1-aminocyclopropanecarboxylic acid, and its pharmaceutically acceptable esters, salts, and acid addition salts or 7-chlorokynurenic acid, and its pharmaceutically acceptable esters, amides, salts, ethers, and acid addition salts.

Abstract: The present invention is directed to compounds useful as probes for characterizing and studying the adenosine A.sub.2 receptor. The present invention is also directed to methods of treating central nervous system disorders and cardiovascular disorders which include treating hypertension and thrombosis by administering said compounds.

Abstract: A method is disclosed for the treatment of mood disorders, including major depression, by administering an effective mood disorder treating amount of a compound possessing functional antagonist properties for the N-methyl-D-aspartate receptor complex.

Abstract: A rapid and sensitive radioreceptor assay for measuring benzodiazepines in plasma and other biological specimens is described. This method is based on the competition between [.sup.3 H] diazepam or tritiated flunitrazepam and pharmacologically active benzodiazepines present in plasma, for binding sites on rat brain synaptosomal membranes. No interference is obtained with drug-free plasma or plasma samples containing high concentrations of other commonly used drugs. High correlations (r=0.98; p<0.001) were obtained between the "diazepam equivalents" measured in plasma using the radioreceptor assay and the levels of diazepam and N-demethyl diazepam obtained by gas-liquid chromatography. The radioreceptor assay is rapid, sensitive, specific, and requires no sophisticated equipment or methodology. It should therefore prove useful in monitoring blood benzodiazepine levels for both therapeutic and toxicologic purposes.
