Various substituted 2(3)-(4-fluorophenyl)-3(2)-(pyridin-4-yl)quinoxatines and 2(3)-(4-fluorophenyl)3(2)-(pyridin-4-yl)pyridopyrazines were synthesized as novel p38 alpha MAP kinase inhibitors via different short synthetic strategies with high variation possibilities. The formation of the quinoxaline/pyridopyrazine core was achieved from alpha-cliketones and o-phenylenodiamines/alpha-diaminopyridines under microwave irradiation. Introduction of an amino moiety at the pyridine C2 position of the 2(3)-(4-fluorophenyl)-3(2)-(pyridin-4-yl)quinoxalines led to compounds showing potent enzyme inhibition down to the double-digit nanomolar range (6f; IC50 = 81 nM). Replacement of the quinoxaline core with pyrido[2,3-b]pyrazine gave compound 9e with superior p38 alpha MAP kinase inhibition (IC50 = 38 nM).

[EN] The invention relates to 2-sulfinyl- or 2-sulfonyl-substituted imidazole derivatives of the formula (I) in which the radicals R1, R2, R3 and R4 have the meaning indicated in the description. The compounds of the invention have an immunomodulating and/or cytokine release-inhibiting effect and are therefore suitable for the treatment of disorders associated with an impairment of the immune system. [FR] La présente invention concerne des dérivés d'imidazole de 2-sulfinyle et de 2-sulfonyle de la formule (I) dans laquelle les radicaux R1, R2, R3 et R4 possèdent la signification indiquée dans la description. Les composés de l'invention présentent un effet immunomodulateur et/ou d'inhibition de libération des cytokines et, par conséquent, sont appropriés pour le traitement de désordres associés aux troubles du système immunitaire.
