Pyrrolidone carboxamides of formula (I) where R2 = a group of formula (a) or (b), R5 = phenyl, heteroalkyl, aryloxy, alkoxy, alkanoyl or -NR6R7 and R1, X, R3, R4, R6 and R7 have the meanings given in the description and the claims, pharmaceutically applicable acid addition salts with basic compounds of formula (I), pharmaceutically applicable salts of acid compounds of formula (I) with bases, pharmaceutically applicable esters of hydroxy- or carboxy- group containing compounds of formula (I) and hydrates and solvates thereof, inhibit the interaction of neuropeptide Y (NPY) with one of the neuropeptide receptor subtypes (NPY-Y5) and are particularly suitable for the prevention and treatment of arthritis, diabetes and especially eating disorders and obesity. The above can be produced by known methods and converted into a galenic dosage form.

L'invention concerne des carboxamides de pyrrolidone de formule (I) dans laquelle R?2¿ désigne un reste de formule (a) ou (b), R?5¿ désigne phényle, hétéoralkyle, aryloxy, alcoxy, alcanoyle ou NR?6¿R?7¿ et R?1¿, X, R?3¿, R?4¿, R?6¿ et R?7¿ ont la signification mentionnée dans la description et les revendications, des sels d'addition d'acide de composés basiques de formule (I) utilisables pharmaceutiquement, des sels de composés acides de formule (I) utilisables pharmaceutiquement, avec des bases, des composés de formule (I) contenant des esters de groupes hydroxy ou carboxy, utilisables pharmaceutiquement, ainsi que leurs hydrates ou solvates. Ces composés inhibent l'interaction du neuropeptide Y (NPY) avec un sous-type de récepteur de neuropeptide (NPY-Y5) et s'utilisent notamment dans la prévention et le traitement de l'arthrite, du diabète et spécialement des troubles de la nutrition et de l'obésité. Lesdits composés peuvent être obtenus selon des procédés connus en soi et être présentés sous des formes d'administration galéniques.
