représente un groupe partant dérivé par exemple de benzotriazole, d'acylurée ou un atome d'halogène et R2 est tel que défini ci-dessus, en utilisant les méthodes connues de l'Homme du métier.
Les composés de formule générale (I) dans laquelle R représente l'atome d'hydrogène peuvent être aussi préparés à partir de composés de formule générale (I) dans laquelle R représente :
- soit un groupe protecteur que l'on peut déprotéger par hydrogénolyse, - soit un groupe allyle, en déprotégeant l'azote, par exemple par un complexe du palladium zéro , selon les méthodes connues de l'Homme du métier.
Les composés de formule générale (I) dans laquelle R est différent de l'atome d'hydrogène peuvent être aussi préparés à partir de composés de formule générale (I) dans laquelle R représente un atome d'hydrogène, soit par alkylation dudit composé de formule générale (I) avec un halogénure ou mésylate du type RX, dans lequel R est tel que défini ci-dessus et X est mésylate ou halogène, en présence d'une base minérale, par exemple le carbonate de potassium dans l'acétonitrile ; soit par une réaction de type Eschweiler-Clarke ou une amination réductrice avec un aldéhyde ou une cétone appropriés selon les méthodes connues de l'Homme du métier ; soit avec un dérivé époxyde approprié, selon les méthodes connues de l'Homme du métier.

L'amine (V) peut-être déprotégée en utilisant un lithien de type phényllithium dans un solvant tel que le tétrahydrofurane à basse température, par exemple à
-70 C. On procède ensuite à une N-allylation au moyen du bromure d'allyle en présence d'une base telle que le carbonate de potassium, dans un solvant tel que l'acétonitrile à température ambiante, pour obtenir le composé (VII). On fait réagir l'amide morpholinique de formule (VII) avec l'aromatique lithié de formule générale (VIII), dans laquelle R, est tel que défini ci-dessus, dans un solvant éthéré
tel que l'éther ou le tétrahydrofurane, à basse température. On obtient ainsi une cétone de formule générale (IX) que l'on fait réagir avec le chlorhydrate de la O-benzylhydroxylamine, au reflux de la pyridine, pour obtenir un mélange d'oxime Z/E

Le jour de l'expérience, le milieu de culture est éliminé et les cellules sont lavées par un tampon Krebs-HEPES (acide [4-(2-hydroxyéthyl)pipérazine-1-éthanesulfonique) à pH 7,4. Après 10 min de préincubation à 37 C en présence soit de tampon (lot témoin), soit de composé à tester à différentes concentrations ou de 10 mM de glycine (détermination de la capture non spécifique), 10 pM de [14C]glycine (activité spécifique 112 mCi/mmole) sont ensuite ajoutés. L'incubation se poursuit pendant 10 min à 37 C, et la réaction est arrêtée par 2 lavages avec un tampon Krebs-HEPES à pH 7,4. La radioactivité incorporée par les cellules est alors estimée après ajout de 100 pl de scintillant liquide et agitation pendant 1 h. Le comptage est réalisé sur compteur Microbeta Tri-IuxTM.

Incubation is continues for 10 min at 37 ° C., and the reaction is stopped by 2 washes with a buffer Krebs-HEPES at pH 7.4. The radioactivity incorporated by the cells is then estimated after addition of 100 μl of liquid scintillant and stirring for 1 h. The counting is performed on Microbeta Tri-IuxTM counter. The effectiveness of the compound is determined by the C150, concentration of the compound which decreases by 50% the specific capture of glycine, defined by the difference in radioactivity incorporated by the control group and the lot that has received glycine at 10 mM.
