Definitions
- the present invention relates to new piperidines derived from aryl piperazine, as well as to their process of preparation, the pharmaceutical compositions containing them and their use as medicaments.
- Serotonin or 5-hydroxytryptamine (5 -HT) is a neurotransmitter and neuromodulator of the central nervous system involved in many physiological and pathological processes. Serotonin plays an important role both in the nervous system and in the cardiovascular and gastrointestinal systems. At the central level, serotonin controls functions as varied as sleep, locomotion, food intake, learning and memory, endocrine modulations, sexual behavior, thermoregulation. In the marrow, serotonin plays an important role in the control systems of the afferent peripheral nociceptives (cf. A. Moulignier, Rev. Neurol. (Paris), 1 50, 3 - 1 5, 1 994).
- Serotonin can play an important role in various types of pathological conditions such as certain psychiatric disorders (anxiety, depression, aggression, panic attacks, obsessive compulsive disorders, schizophrenia, tendency to suicide), certain neurodegenerative disorders (dementia of the ⁇ lzheimer type , Parkinsonism, Huntington's chorea), anorex, bulimia, alcohol-related disorders, cerebrovascular accidents, pain, migraine or various headaches (R. G lennon, Neurosci. Biobehavioral Reviews 14.35, 1 990). Numerous recent pharmacological studies have demonstrated the diversity of serotonin receptors as well as their respective involvement in its various modes of action (cf. E. Zifa, G.
- the receptors 5HTjr_ themselves contain many ur receptor subtypes; thus the receptors 5HT ⁇ r ja and 5HTi £) b were cloned and then identified in humans (cf. for example E. Hamel et al., Mol. Pharmacol., 4_4, 242, 1993; GW Rebeck et al. ., Proc. Natl. Acad. Sci. USA, 9_L, 3666.1994). Furthermore, it has recently been demonstrated that the 5HTj ⁇ auto-receptors in rodents and 5HTj £) in other species are capable of controlling the release of serotonin in nerve endings (cf. M. Briley, C. Moret, Cl.
- Compounds having a selective antagonist activity at the level of central SHTJD receptors can therefore exert a beneficial effect on subjects suffering from disorders of the central nervous system.
- such compounds find their use in the treatment of locomotion disorders, depression, anxiety, panic attacks, agoraphobia, obsessive compulsive disorders, memory disorders including dementia, amnesia , and appetite disorders, sexual dysfunctions, Alzheimer's disease, Parkinson's disease.

- the compounds according to the present invention are powerful and selective antagonists of 5HT ⁇ j3 receptors and more particularly receptors recently identified as 5HT ⁇ rj a and 5HT ⁇ r3b in humans and, therefore, find their utility, alone or in combination with other molecules. , as drugs and more particularly as therapeutic means for both curative and preventive treatment of disorders related to serotonin.
- the derivatives of the present invention are distinguished from the prior art not only by their original chemical structure which distinguishes them without ambiguity of the previously described derivatives may also be due to their original biological profile, in particular with regard to their selectivity for the serotonin receptor subtypes and with regard to their antagonistic activity in particular at the receptors known as name 5-HT j rj ⁇ .
