The present invention relates to pyridylpyrimidine derivatives of the general formula (I) : wherein R represents hydrogen or methyl and Z represents nitrogen containing functional groups, the use of the pyridylpyrimidine derivatives as pharmaceutically active agents, especially for the prophylaxis and/or treatment of prion infections and prion diseases, as well as compositions containing at least one pyridylpyrimidine derivative and/or pharmaceutically acceptable salt thereof. Furthermore, the present invention is directed to methods for preventing and/or treating prion infections and prion diseases using said pyridylpyrimidine derivatives. Human cellular protein kinases, phosphatases and cellular signal transduction molecules are disclosed as targets for detecting, preventing and/or treating prion infections and diseases, especially BSE, vCJD, or CJD, which can be inhibited by the inventive pyridylpyrimidine derivatives.

La présente invention concerne des dérivés de pyridylpyrimidine de formule générale (I), dans laquelle R représente un atome d'hydrogène ou un groupe méthyle et Z représente un atome d'azote contenant des groupes fonctionnels. L'invention concerne également l'utilisation de ces dérivés de pyridylpyrimidine comme agents pharmaceutiquement actifs, en particulier en prévention et/ou traitement d'infections et de maladies à prions, ainsi que des compositions contenant au moins un dérivé de pyridylpyrimidine et/ou un sel pharmaceutiquement acceptable de celui-ci. L'invention concerne en outre des procédés de prévention et/ou traitement d'infections et de maladies à prions au moyen de ces dérivés de pyridylpyrimidine. Par ailleurs, des protéines kinases cellulaires humaines, des phosphatases et des molécules de transduction de signal cellulaire sont présentées en tant que cibles pour la détection, la prévention et/ou le traitement d'infections et de maladies à prions, en particulier l'ESB, la vMCJ ou la MCJ, qui peuvent être inhibées par les dérivés de pyridylpyrimidine faisant l'objet de l'invention.
