The ester (IV) is converted to the amide (V) by heating the trimethylaluminium complex and the appropriate amine, such as morpholine, at reflux of the solvent, such as toluene. The amine (V) can be deprotected by using a lithium compound of phenyliithium type in a solvent, such as tetrahydrofuran, at low temperature, for example at -70°C. An N-allylation is subsequently carried out using allyl bromide in ’ 10 the presence of a base, such as potassium carbonate, in a solvent, such as acetonitrile, at ambient temperature, in order to obtain the compound (VII). The morpholine amide of formula (VII) can be reacted with the lithiated aromatic compound of general formula (VIII), in which R, is as defined above, in an ethereal solvent, such as ether or tetrahydrofuran, at low temperature. A ketone of general formula (IX) is thus obtained and is reacted with O-benzylhydroxylamine hydrochloride, at reflux of pyridine, in order to obtain a Z/E mixture of oxime of general formula (X).

The compounds of the invention have been subjected fo a series of pharmacological trials which have demonstrated their advantage as substances possessing therapeutic activities.
Study of glycine transportation in SK-N-MC cells expressing the native human transporter GiyT1. :
The uptake of [“*Clglycine is studied in SK-N-MC cells (human neuroepithelial cells) expressing the native human transporter GlyT1 by measuring the radioactivity "incorporated in the presence or absence of the test compound. The cells are cultured ‘as a monolayer for 48 hours in plates pretreated with 0.02% fibronectin. On the dayof the experiment, the culture medium is removed and the cells are washed with
Krebs-HEPES (4-(2-hydroxyethyl)piperazine-1-ethanesulphonic acid) buffer at pH 7.4.
After preincubation for 10 minutes at 37°C in the presence either of buffer (control batch) or of test compound at various concentrations or of 10 mM of glycine
(determination of the non-specific uptake), 10 uM of ["“Clglycine (specific activity 112 mCi/mmol) are subsequently added. Incubation is continued for 10 min at 37°C and the reaction is halted by washing twice with pH 7.4 Krebs-HEPES buffer. The radioactivity incorporated by the cells is then estimated after adding 100 pl of liquid scintillant and stirring for 1 h. Counting is carried out on a Microbeta Tri-Lux™ counter. : The effectiveness of the compound is determined by the ICs;, the concentration of the compound which reduces by 50% the specific uptake of glycine, defined by the difference in radioactivity incorporated by the control batch and the batch which received the 10 mM glycine.
The compounds of the invention have, in this test, an ICs of the order of 0.01 to 10 uM.
Some examples of Cg results for compounds according to the invention are shown in
Table 3.

Ointments, lotions and collyria can be envisaged for topical administration. :
The said unit forms are dosed to allow a daily administration of 0.01 to 20 mg of active principie per kg of body weight, according to the pharmaceutical dosage form.
To prepare tablets, a pharmaceutical vehicle, which can be composed of diluents, such as, for example, lactose, microcrystalline cellulose or starch, and formulation adjuvants, such as binders (polyvinylpyrrolidone, hydroxypropylmethylceliulose, and the like), flow agents, such as silica, or lubricants, such as magnesium stearate, stearic acid, glyceryl tribehenate or sodium stearylfumarate, is added to the micronized or unmicronized active principle. Wetting or surface-active agents, such as sodium lauryt sulphate, can also be added.
The preparation techniques can be direct tableting, dry granulation, wet granulation or hot melt.
The tablets can be bare, coated with sugar, for example with sucrose, or coated with various polymers or other appropriate materials. They can be designed to make possible rapid, delayed or sustained release of the active principle by virtue of polymer matrices or of specific polymers used in the coating.
To prepare gelatin capsules, the active principle is mixed with dry pharmaceutical vehicles (simple mixing, dry or wet granulation, or hot melt) or liquid or semisolid pharmaceutical vehicles.
The gelatin capsules can be hard or soft and coated or uncoated with a thin film, so as to have a rapid, sustained or delayed activity (for example, for an enteric form).
A composition in the form of a syrup or an elixir or for administration in the form of drops can comprise the active principle in conjunction with a sweetener, preferably a calorie-free sweetener, methylparaben or propylparaben, as antiseptic, a flavour enhancer and a colorant.
The water-dispersible powders and granules can comprise the active principle as a mixture with dispersing agents or wetting agents, or dispersing agents, such as polyvinylpyrrolidone, as well as with sweeteners and flavour-correcting agents.
Recourse is had, for rectal administration, to suppositories prepared with binders which melt at the rectal temperature, for example cocoa butter or polyethylene glycols.
Use is made, for parental administration, of aqueous suspensions, isotonic saline solutions or injectable sterile solutions comprising pharmacologically compatible dispersing agents and/or wetting agents, for example propylene glycol or butylene glycol.
The active principle can aiso be formulated in the form of microcapsules, opftionaily with one or more vehicles or additives or else with a polymer matrix or with a cyclodextrin (patches or sustained release forms).
The topical compositions according to the invention comprise a medium compatible with the skin. They can be provided in particular in the form of aqueous, alcoholic or aqueous/alcoholic solutions, of gels, of water-in-oil or oil-in-water emulsions having the appearance of a cream or of a gel, of microemulsions or of aerosols or in the form of vesicular dispersions comprising ionic and/or nonionic lipids.
