(EN) This invention relates to certain 5-(optionally substituted aryl or heteroaryl)-4-(optionally substituted heteroaryl)-1-(optionally substituted heterocyclyl or heterocyclylalkyl) or 1- optionally substituted alkyl or alkenyl -imidazoles and derivatives thereof. Synthetic processes for the preparation of said tri-substituted imidazoles is described. The aforementioned imidazoles are useful for treating cytokine mediated diseases. The compounds of the invention are incorporated into pharmaceutical compositions for use in treating cytokine related diseases.(FR) L'invention concerne certains imidazoles 5-(aryle ou hétéroaryle éventuellement substitué)-4-(hétéroaryle éventuellement substitué)-1-(hétérocyclyle ou hétérocyclylalkyle éventuellement substitué) ou 1-alcényle ou alkyle éventuellement substitué et des dérivés de ces imidazoles. L'invention concerne également des procédés de synthèse pour la préparation de ces imidazoles trisubstitués. Ces imidazoles sont utiles pour traiter les maladies induites par la cytokine. Les composés de l'invention sont incorporés dans des compositions pharmaceutiques permettant de traiter les maladies liées à la cytokine.

Novel potent and selective diarylimidazole inhibitors of p38 MAP (mitogen-activated protein) kinase are described which have activity in both cell-based assays of tumor necrosis factor-alpha (TNF-alpha) release and an animal model of rheumatoid arthritis; The SAR leading to the development of selectivity against c-Raf and JNK2 alpha 1 kinases is presented, with key features being substitution of the 4-aryl ring with m-trifluoromethyl and substitution of the 5-heteroaryl ring with a a-amino substituent. Cell-based activity was significantly enhanced by incorporation of a 4-piperidinyl moiety at the 2-position of the imidazole which also enhanced aqueous solubility. In general, oral bioavailability of this class of compounds was found to be poor unless the imidazole was methylated on nitrogen. This work led to identification of 48, a potent (p38 MAP kinase inhibition IC50 0.24 nM) and selective p38 MAP kinase inhibitor which inhibits lipopolysaccharide-stimulated release of TNF-alpha from human blood with an IC50 2.2 nM, shows good oral bioavailability in rat and rhesus monkey, and demonstrates significant improvement in measures of disease progression in a rat adjuvant-induced arthritis model.
