2,4-Dianilino pyrimidines are well-known inhibitors of tyrosine kinases including lymphocyte specific kinase (Lek). Structure-activity relationships at the 4-position are discussed and rationalised. Examples bearing a 2-methyl-5-hydroxyaniline substituent at the 4-position were especially potent but showed poor oral pharmacokinetics. Replacement of this substituent by 4-amino(5methyl-IH-indazole) yielded compounds with comparable enzyme potency and improved pharmacokinetic properties. (c) 2007 Elsevier Ltd. All rights reserved.

[EN] Bis-anilinopyrimidine compounds of the formula (I); are useful as inhibitors of spleen tyrosine kinase (Syk) and thus useful in treating diseases resulting from in appropriate mast cell activation, for instance allergic and inflammatory diseases. [FR] L'invention concerne des composés bis-anilinopyrimidine de la formule (I), qui sont utilisés comme inhibiteurs de la tyrosine kinase de la rate (Syk) et qui sont par conséquent utiles dans le traitement de maladies causées par une activation inappropriée des mastocytes, par exemple dans les maladies allergiques et inflammatoires.
