  • Patent number: 6413956
    Abstract: Disclosed are compounds of Formula I: or the pharmaceutically acceptable salts thereof where, R1, R2, and W are defined herein. These compounds are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs of agonists, antagonists or inverse agonists for GABAa brain receptors and are therefore useful in the diagnosis and treatment of anxiety, depression, Down Syndrome, sleep and seizure disorders, overdose with benzodiazepine drugs and for enhancement of memory. Pharmaceutical compositions, including packaged pharmaceutical compositions, are further provided. Compounds of the invention are also useful as probes for the localization of GABAA receptors in tissue samples.

  • Patent number: 6323197
    Abstract: The invention concerns compounds of formula (I), in which R1, R2, R3 and R4 mean hydrogen or different substituents; X means hydrogen or halogen; Y means C1-6 alkoxy or X and Y together mean —O—(CH2)n—O—; n means 1, 2 or 3; and A together with nitrogen forms a saturated or unsaturated five-member heterocycle which can contain between 1 and 3 nitrogen atoms and/or an oxygen atom and/or one or two carbonyl groups. Owing to their non-competitive inhibiting of the AMPA receptors, these compounds can be used as medicaments for treating diseases of the central nervous system.
