摘要

Compounds of formula (I) or pharmaceutically acceptable salts or solvates thereof, where Q is a monocyclic or bicyclic aryl or heteroaryl ring, R1 is hydrogen, C¿1-6?alkyl (optionally substituted by hydroxy or C1-4alkoxy), C1-6alkenyl, C1-6alkynyl, C1-6alkylCO-, formyl, CF3CO- or C1-6alkylSO2-, R?2¿ is hydrogen or up to three substituents selected from halogen, NO¿2?, CN, N3, CF3O-, CF3S-, CF3CO-, trifluoromethyldiazirinyl, C1-6alkyl, C1-6alkenyl, C1-6alkynyl, C1-6perfluoroalkyl, C3-6cycloalkyl, C3-6cycloalkyl-C1-4alkyl-, C1-6alkylO-, C1-6alkylCO-, C3-6cycloalkylO-, C3-6cycloalkylCO-, C3-6cycloalkyl-C1-4alkylO-, C3-6cycloalkyl-C1-4alkylCO-, phenyl, phenoxy, benzyloxy, benzoyl, phenyl-C1-4alkyl-, C1-6alkylS-, C1-6alkylSO2-, (C1-4alkyl)2NSO2-, (C1-4alkyl)NHSO2-, (C1-4alkyl)2NCO-, (C1-4alkyl)NHCO, CONH2, CF3SO2, C1-6alkenyl, C1-6alkynyl or C1-6hydroxyalkyl; or -NR?3R4¿ where R3 is hydrogen or C¿1-4?alkyl, and R?4¿ is hydrogen, C¿1-4?alkyl, formyl, -CO2C1-4alkyl or -COC1-4alkyl; or two R?2¿ groups together form a carbocyclic ring that is saturated or unsaturated and unsubstituted or substituted by -OH or =O; and X is halogen, C¿1-6?alkoxy, C1-6alkyl, C2-6alkenyl optionally substituted by phenyl; are useful in the treatment and/or prophylaxis of anxiety, mania, depression, panic disorders and/or aggression, disorders associated with a subarachnoid haemorrhage or neural shock, the effects associated with withdrawal from substances of abuse such as cocaine, nicotine, alcohol and benzodiazepines, disorders treatable and/or preventable with anti-convulsive agents, such as epilepsy including post-traumatic epilepsy, Parkinson's disease, psychosis, migraine, cerebral ischaemia, Alzheimer's disease and other degenerative diseases such as Huntingdon's chorea, schizophrenia, obsessive compulsive disorders (OCD), neurological deficits associated with AIDS, sleep disorders (including circadian rhythm disorders, insomnia and narcolepsy), tics (e.g. Giles de la Tourette's syndrome), traumatic brain injury, tinnitus, neuralgia, especially trigeminal neuralgia, neuropathic pain, dental pain, cancer pain, inappropriate neuronal activity resulting in neurodysthesias in diseases such as diabetes, multiple sclerosis (MS) and motor neurone disease, ataxias, muscular rigidity (spasticity), temporomandibular joint dysfunction, or amyotrophic lateral sclerosis (ALS).
