Abstract: A class of compounds is disclosed, comprising sulphonamido-substituted bridged bicycloalkyl structures. The compounds are inhibitors of gamma-secretase, and hence are useful in the treatment of and/or prevention of Alzheimer's disease.

Abstract: There is disclosed a novel class of sulphonamido-substituted bridged bicycloalkyl derivatives comprising a substitute on the bridgehead position. The compounds modulate the production of the ?-amyloid precursor protein, and hence are useful in the treatment of Alzheimer's Disease.

Abstract: Novel sulfamides of formula (I) are disclosed. The compounds exert an inhibitory action on the processing of APP by gamma-secretase, and are therefore useful in the treatment or prevention of Alzheimer's disease.

Abstract: A novel class of 1,4- and 1,5-benzodiazepines of formula (I) is disclosed.

Abstract: There is disclosed a novel class of sulphonamido-substituted bridged bicycloalkyl derivatives comprising a substitute on the bridgehead position. The compounds modulate the production of the &bgr;-amyloid precursor protein, and hence are useful in the treatment of Alzheimer's Disease.

Abstract: A novel class of 1,4- and 1,5-benzodiazepines of formula (I) is disclosed. The compounds modulate the processing of amyloid precursor protein by &ggr;-secretase, and hence find use in the treatment or prevention of conditions associated with the deposition of &bgr;-amyloid, such as Alzheimer's disease.

Abstract: Novel sulfamides of formula (1) are disclosed. The compounds exert an inhibitory action on the processing of APP by gamma-secretase, and are therefore useful in the treatment or prevention of Alzheimer's disease.

Abstract: Compounds according to Formula (I) or a salt thereof are selective ligands for GABAA receptors useful for treatment of disorders of the central nervous system:

Abstract: 1,2,4-triazolo[4,3-b]pyridazine derivatives, represented by wherein Z represents an optionally substituted tetrahydropyridinyl substituent, are selective ligands for GABAA receptors, in particular having high affinity for the &agr;2 and/or &agr;3 subunit thereof, are useful in the treatment of anxiety and convulsions.

Abstract: 1,2,4-triazolo[4,3-b]pyridazine derivatives, represented by wherein Z represents cyclobutyl, 1-methylcyclopentyl or pyrrolidin-1-yl, are selective ligands for GABAA receptors, in particular having high affinity for the &agr;2 and/or &agr;3 subunit thereof, are useful in the treatment of anxiety and convulsions.

Abstract: Compounds according to Formula (I) or a salt thereof are selective ligands for GABAA receptors useful for treatment of disorders of the central nervous system: 1

Abstract: Substituted 1H-Pyridinyl-2-ones are useful as GABAA-Alpha 2/3 ligands.

Abstract: The present patent application discloses compounds having formula (I) ##STR1## or a pharmaceutically acceptable salt thereof or an oxide thereof, wherein R.sup.3 is (II), ##STR2## wherein A, B and D each is CH, or one or two of A, B and D is N and the others are CH; R.sub.11 is phenyl, benzimidazolyl, or monocyclic heteroaryl all of which may be substituted one or more times with substituents selected from alkyl, alkoxy, phenyl, halogen, CF.sub.3, amino, nitro, cyano, acyl, acylamino, phenyl and monocyclic heteroaryl; and one of R.sup.6 and R.sup.7 is hydrogen and the other is furanyl or isoxazolyl each of which may be substituted one or more times with substituents selected from halogen, alkyl, alkoxy and phenyl. The compounds are useful for the treatment of various central nervous system disorders such as epilepsy and other convulsive disorders, anxiety, sleep disorders and memory disorders.
