Summary:Novel pyridopyrimidine-based compounds are found to be useful for the treatment or prevention of symptoms or manifestations associated with diseases or disorders affected by cytokine intracellular signaling, having the following formula: formula (I) wherein R1 is selected from a member of the group consisting of hydrogen, hydroxyl, methoxyl, N-OH, acylamino group, cyano group, sulfo, sulfonyl, sulfinyl, sulfhydryl (mercapto), sulfeno, sulfanilyl, sulfamyl, sulfamino, and phosphino, phosphinyl, phospho phosphono and -NRaRb, wherein each of Ra and Rb may be the same or different and each is selected from the group consisting of hydrogen and optionally substituted: C(1-20)alkyl, C(1-20)cycloalkyl, C(1-20)alkenyl, C(1-20)cycloalkenyl, C(1-20)alkynyl, aryl, heteroaryl, and heterocyclic group. R2 and R3 are independently selected from a member of the group consisting of halo, thio, oxo, C(1-20)alkyl, C(1-20)hydroxyalkyl, C(1-20)thioalkyl, C(1-20)alkylthio, C(1-20)alkylamino, C(1-20)alkylaminoalkyl, C(1-20)aminoalkyl, C(1-20)aminoalkoxyalkenyl, C(1-20)aminoalkoxyalkynyl, C(1-20)diaminoalkyl, C(1-20)triaminoalkyl, C(1-20)tetraaminoalkyl, C(1-20)aminotrialkoxyamino, C(1-20)alkylamido, C(1-20)alkylamidoalkyl, C(1-20)amidoalkyl, C(1-20)acetamidoalkyl, C(1-20)alkenyl, C(1-20)alkynyl, C(1-20)alkoxyl, C(1-20)alkoxyalkyl, C(1-20)dialkoxyalkyl, and NraRb. R4 may be hydrogen or an optionally substituted member of the group consisting of C(1-20)alkyl, C(1-20)cycloalkyl, C(1-20)alkenyl, C(1-20)cycloalkenyl, C(1-20)alkynyl, aryl, heteroaryl, and heterocyclic group. L'invention porte sur de nouveaux composés à base de pyridopyrimidine qui s'avèrent être utiles dans le traitement et la prévention de symptômes ou manifestations associés à des maladies ou troubles provoqués par la signalisation intracellulaire de la cytokine, ces composés ayant la formule (I) dans laquelle R1 est sélectionné à partir d'un élément du groupe comprenant hydrogène, hydroxyle, méthoxyle, N-OH, le groupe acylamino, le groupe cyano, sulfo, sulfonyle, sulfinyle, sulfhydryl (mercapto), sulfeno, sulfanilyle, sulfamyle, sulfamino, et phosphino, phosphinyle, phospho phosphono et -NRaRb, où chacun de Ra et Rb peut être identique ou différent, et chacun est sélectionné dans le groupe comprenant hydrogène et éventuellement substitué: C(1-20)alkyle, C(1-20)cycloalkyle, C(1-20)alcényle, C(1-20)cycloalcényle, C(1-20)alkynyle, aryle, hétéroaryle et le groupe hétérocyclique. R2 et R3 sont sélectionés indépendamment à partir d'un élément du groupe comprenant halo, thio, oxo, C(1-20)alkyle, C(1-20)hydroxyalkyle, C(1-20)thioalkyle, C(1-20)alkylthio, C(1-20)alkylamino, C(1-20)alkylaminoalkyle, C(1-20)aminoalkyle, C(1-20)aminoalcoxyalcényle, C(1-20)aminoalkoxyalkynyle, C(1-20)diaminoalkyle, C(1-20)triaminoalkyle, C(1-20)tétraaminoalkyle, C(1-20)aminotrialkoxyamino, C(1-20)alkylamido, C(1-20)alkylamidoalkyle, C(1-20)amidoalkyle, C(1-20)acétamidoalkyle, C(1-20)alcényle, C(1-20)alkynyle, C(1-20)alcoxyle, C(1-20)alcoxyalkyle, C(1-20)dialcoxyalkyle et NraRb. R4 peut être hydrogène ou éventuellement un élément substitué du groupe comprenant C(1-20)alkyle, C(1-20)cycloalkyle, C(1-20)alcényle, C(1-20)cycloalcényle, C(1-20)alkynyle, aryle, hétéroaryle et le groupe hétérocyclique.
