Abstract: The invention relates to heterocyclic aminoalkylpyridine derivatives of the formula I: where R1 is the radical of a heterocycle having 1 to 3 ring structures, where each ring structure is saturated, unsaturated or aromatic and optionally fused to other ring structures to give a fused ring system and the heterocycle has a total of 1 to 4 N, O and/or S atoms in the ring structures and is optionally monosubstituted, disubstituted or trisubstituted by one or more of the groups -A, —OR4, —N(R4)2, —NO2, —CN, Hal, —COOR4, —CON(R4)2, —COR4, ?O; R2 is a phenyl group which is optionally monosubstituted, disubstituted, trisubstituted, tetrasubstituted or pentasubstituted by one or more of the groups Hal, -A, —O-A, —NO2 or —CN, or is a thienyl group which is optionally monosubstituted or disubstituted by one or more of the groups Hal, -A, —O-A, -NO2, —CN or thienyl; R3 is H, -A, —CO-A, —C(R4)2R2, —C(R4)2-pyridinediyl-R2; R4 is H or -A; A is C1-C6-alkyl, where 1 to 7 hydrogen atoms are optionally replaced by fluor

Abstract: Amide and urea derivatives of the formula I R1—(CH2)n—(Y)q-(Z)r-CO—NH—R2 ??(I) in which R1, n, Y, q, Z, r and R2 have the meanings indicated in claim 1, are potent 5-HT1B/1D antagonists and exhibit 5-HT reuptake-inhibiting actions and are suitable for the treatment and prophylaxis of anxiety states, depressions, schizophrenia, compulsive ideas, tardive dyskinesias, learning disorders, age-dependent memory disorders, for positively affecting obsessive-compulsive behaviour (OCD), and also for the treatment and for the control of the sequelae of cerebral infarcts such as stroke and cerebral ischaemias.

Abstract: The invention relates to compounds of formula (I) wherein R1, R2, R4 and R5 have the meaning given in Claim 1. Said compounds are potent 5-HT2A-antagonists and are suitable for the treatment of psychosis, schizophrenia, depression, neurological disorders, memory disorders. Parkinson's disease, amyntrophic lateral schlerosis, Alzheimer's disease, Huntington's disease, eating disorders, e.g. nervous bulimia and anorexia and premenstrual syndrome and/or for positively influencing compulsive behaviours (obsessive-compulsive disorder, OCD).

Abstract: The invention relates to compounds of formula (I), wherein R1, R2 and A have the meanings given in claim 1, are potent 5-HT2A antagonists and are suitable for treating psychoses, schizophrenia, depression, neurological disorders, impaired memory, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer's disease, Huntington's disease, eating disorders such as bulimia and anorexia nervosa, Pre-Menstrual Syndrome and/or for positively influencing obsessive-compulsive disorders, (OCD).

Abstract: Indole derivatives of formula I, their salts and solvates, have valuable pharmacological properties together with good tolerability, as they have actions on the central nervous system: wherein R1 and R3 are as defined herein. The compounds have a strong affinity for 5-HT2A receptors, and furthermore exhibit 5HT2A receptor-antagonistic properties. These are therefore suitable both in veterinary and in human medicine for the treatment of functional disorders of the central nervous system and also of inflammation.
