摘要:
A process for preparing [1H]-isoindolin-1-one-3-carboxylic acid comprising the steps of (1) reacting phthalaldehydic acid in an alkanol with ammonia, (2) contacting the resulting solution with an alkali metal cyanide, (3) removing the alkanol, (4) adjusting the pH to 1.0, (5) heating the resulting reaction mixture until product formation is substantially complete and isolating the product.

This invention relates to pyridazine derivatives, compositions comprising therapeutically effective amounts of those pyridazine derivatives and methods of using those derivatives or compositions in treating central nervous system (CNS) disorders with cognitive impairment that are responsive to agonists of α5 subunit containing GABAA receptor, e.g., age-related cognitive impairment, Mild Cognitive Impairment (MCI), dementia, Alzheimer's Disease (AD), prodromal AD, post traumatic stress disorder (PTSD), schizophrenia and cancer-therapy-related cognitive impairment.
摘要:
The present invention relates to a series of substituted bicyclic[3.1.0]heteroaryl amides of the Formula I, wherein A, Q, X, Y, Z and R1-R5 groups are defined as in the specification, that exhibit activity as glycine transport inhibitors, their pharmaceutically acceptable salts, pharmaceutical compositions containing them, and their use for the enhancement of cognition and the treatment of the positive and negative symptoms of schizophrenia and other psychoses in mammals, including humans.
摘要:
The present invention relates to 2-aminopyridine derivatives of the formula I: or pharmaceutically acceptable salts thereof, wherein A and B are each independently H, or together, A and B form a ring fused to the phenyl ring, said ring being saturated or unsaturated and containing from 5 to 7 ring member atoms, where said ring member atoms may optionally comprise from 1 to 2 heteroatoms selected independently from the group consisting of N, O or S, provided that no two adjacent ring members are heteroatoms; X is oxygen or a single bond; Y is (C1-C6)alkyl; R1 is hydrogen, (C1-C6)alkyl or a (C1-C6 alkyl) group substituted with —NR2R3 wherein R2 and R3 are either selected independently from the group consisting of H, alkyl, aryl, aralkyl or tetrahydronaphthalene, wherein said aryl group or said aryl moiety of said aralkyl group is phenyl or naphthyl, said alkyl group or said alkyl moiety of said aralkyl group contains from one to six carbon atoms and is straight-chained or branched, and said aryl group, said tetrahydronaphthalene or said aryl moiety of said aralkyl group is optionally substituted with from one to three of halogen, nitro, cyano, amino, (C1-C4)alkoxy and (C1-C4)alkylamino moieties, or R2 and R3 form, together with the nitrogen to which they are attached, a heterocyclic ring, or a cyclic or bicyclic ring which is saturated or unsaturated. The compounds of the invention have the ability to inhibit the activity of nitric oxide synthases (NOS), and hence, are useful in the treatment of diseases, conditions and disorders of the central nervous system, among others.
