Tetrahydropyridine-(or 4-hydroxypiperidine) alkylazoles

The present invention relates to new 4-aryltetra-hydropyridines and 4-arylpiperidinols linked to alkyl-azoles of general formula (I)

and to their physiologically acceptable salts, to the processes for their preparation, to their application as medicaments and to the pharmaceutical compositions which contain them.

The compounds which are the subjects of the invention can also be used in the pharmaceutical industry as intermediates and for the preparation of medicaments.

These compounds possess a powerful affinity for sigma and/or 5-HT

1A

receptors and are therefore potentially useful in the treatment of certain psychic and neurological disorders of human beings and other mammals.

Phenomena exist which involve sigma receptors in the treatment of psychosis. Many atypical antipsychotics, such as rimcazole (Schwarcz, G. et al., Drug Dev. Res., 1985, 5, 387), remoxipride (Wadworth, A. B. et al., Drugs 1990, 40, 863) or thiospirone (Jain, A. K. et al., Int. Clin. Psychopharmacol. 1987, 2, 129), show a significant affinity for sigma receptors.

Moreover, studies of the biology and function of sigma receptors indicate that ligands for the sigma receptor can be effective in the treatment of certain motor disorders, in particular Huntington's chorea, dystonia and Tourette's syndrome. The presence of sigma receptors in the substantia nigra makes it possible to use them in the treatment of Parkinson's disease (Walker, J. M. et al., Pharmacological Reviews, 1990, 42, 355).

Certain ligands for sigma receptors are involved in the modulation of the effects produced by the intervention of the NMDA receptor and act as antiischemic agents in in vivo tests (Rao, T. S. et al., Molecular Pharmacology, 1990, 37, 978), with the possibility of use as neuroprotectors and in the treatment of epilepsy and of convulsion (Kaiser C., Neurotransmissions VII, 1991).

It has been said that ligands for sigma receptors exhibit antiamnesic effects in animal models (Early et al., Brain Research, 1991, 546, 281).

Sigma ligands influence the levels of acetylcholine in animal models (Matsuno et al., Brain Research 1992, 575, 315) and can consequently be used in the treatment of senile dementia, for example of Alzheimer type.

Ligands for 5-HT

1A

receptors, in particular agonists or partial agonists for 5-HT

1A

, show a proven anxiolytic and antidepressant activity (Glitz, D. A., Drugs, 1991, 41, 11).

Consequently, agents having a powerful affinity for sigma and/or 5-HT

1A

receptors can be used in one or a number of the treatments indicated.

Examples of 4-aryl-1,2,3,6-tetrahydropyridines and of 4-aryl-4-hydroxypiperidines are found in the bibliography; however, compounds in which these sub-structures are joined to the nitrogen of an azole ring by means of an unsubstituted alkyl chain are not found to be described:

The Inventors have previously described a series of N-alkylazoles joined to the nitrogen of various heterocycles which are useful as non-benzodiazepine agents in the treatment of anxiety (European Patents No. EP 382637, EP 497659 and EP 502786) and in the treatment of other behavioral disorders (European Patents EP 429360 and EP 497658).

BIOLOGICAL TESTS

BINDING TO THE SEROTONIN RECEPTOR (5-HT

1A

)

A rat hippocampus homogenate is used, a modification of the process of S. J. Peroutka, J. of Neurochem., 47(2), 529-540 (1986) being followed. [

3

H]-8-OH-DPAT is used as radioligand and serotonin is used for measuring the non-specific binding. The incubation time is 15 minutes at a temperature of 37° C. The radioligand bound to the protein is separated by filtration on glass fiber filters and the radioactivity retained on the filter is determined by liquid scintillation. The inhibition constants (K

i

, nM) are calculated by non-linear regression analysis by using the EBDA/LIGAND program (Munson and Rodbard, Analytical Biochemistry, 107, 220 (1980)).

BINDING TO THE SIGMA RECEPTOR

A guinea pig brain (less the cerebellum) homogenate is used, a modification of the process of L. Radesca et al., J. Med. Chem., 34, 3058-3065 (1991) being followed. [

3

H]-(+)-3-PPP is used as radioligand and haloperidol is used for measuring the non-specific binding. The incubation time is 120 minutes at a temperature of 25° C. The radioligand bound to the protein is separated by filtration on glass fiber filters and the radioactivity retained on the filter is determined by liquid scintillation. The inhibition constants (K

i

, nM) are calculated by non-linear regression analysis by using the EBDA/LIGAND program (Munson and Rodbard, Analytical Biochemistry, 107, 220 (1980)).
