The present invention is concerned with new indol-2-one derivatives of Formula (I), which have favorable activity profile for the prophylaxis and treatment of disorders in the central nervous or in the cadiovascular system. 

Piperazine derivatives of alkyl oxindoles

The present invention is concerned with new 3,3-disubstituted indol-2-one derivatives of the general Formula (I), wherein Rstands for hydrogen, halogen, alkyl having 1-7 carbon atom(s) or sulfonamido; Rrepresents hydrogen or halogen; Rdenotes hydrogen, alkyl having 1-7 carbon atom(s) optionally carrying an aryl substituent or aryl optionally carrying one or two halogen substituent(s); Rstands for alkyl having 1-7 carbon atom(s); Rrepresents a group of the general Formula (II a) or (II b), wherein Q and W each represents nitrogen or CH; R, Rand Reach stands for hydrogen, halogen, trifluoromethyl, alkyl or alkoxy having 1-7 carbon atom(s), or Rand Rtogether represent ethylenedioxy; m is 0, 1, or 2; a is a single, double or triple bond; n is 0, 1 or 2; and pharmaceutically acceptable acid addition salts thereof which are useful in the treatment or prophylaxis of diseases of the central nervous system, the gastrointestinal system and the cardiovascular system. 

Piperazine derivatives of dialkyl oxindoles

The invention refers to novel 2H-pyridazine-3-one derivatives of the formula I, pharmaceutical compositions containing the same and a process for the preparation of the active ingredient. The novel compounds possess neuroleptic effect and can be used, primarily, for the treatment of schizophrenia. In formula I, R stands for a hydrogen atom or a C, alkyl group, X and Y represent, independently, a hydrogen atom, a halogen atom or a group of the formula II, with the proviso that one of X and Y means always a group of the formula II, and then the other one stands for a hydrogen atom or a halogen atom, wherein in formula II n has a value of 1 or 2. 

2h-pyridazine-3-one derivatives, pharmaceutical compositions containing the same and a process for the preparation of the active ingredient

The invention relates to substituted alkylaminopyridazinone derivatives of the general Formula (I), (wherein Ris hydrogen or alkyl having 1-4 carbon atoms; one of X and Y stands for hydrogen or halogen and the other represents a group of the general Formula (II), Ris hydrogen or alkyl having 1-4 carbon atoms; n is 1, 2 or 3; Rstands for hydrogen, alkyl having 1-4 carbon atoms or aryl-(Calkyl); Z stands for oxygen; or Rand Z together with the groups placed between them form a piperazine ring; and Rstands for hydrogen, halogen, trifluoromethyl or alkoxy having 1-4 carbon atoms) and pharmaceutically acceptable acid addition salts thereof. The invention compounds are useful in the treatment of anxiolytic conditions and cognitive disorders.
