Patent

CA 2508788

The invention relates to substituted pyrroles of formula (I), in which: R1 represents -OR8 or -NR9R10; R2 represents hydrogen, C1-C6 alkyl or aryl, whereby R2 as an alkyl can be substituted with 0, 1, 2 or 3 substituents R2-1 independently of one another, selected from the group comprising halogen, hydroxy, C1-C6 alkoxy, hydroxycarbonyl, C1-C6 alkoxycarbonyl, C1- C6alkylcarbonyloxy, amino, C1-C6 alkylamino, aminocarbonyl, C1-C6 alkylaminocarbonyl, C3-C8 cycloalkyl, a 5- to 10-membered heterocyclyl, C6-C10 aryl, phenoxy and a 5- to 10-membered heteroaryl and whereby R2 as an aryl can be substituted with 0, 1, 2 or 3 substituents R2-2 independently of one another, selected from the group comprising halogen, hydroxy, nitro, cyano, trifluoromethyl, trifluoromethoxy, C1-C6 alkyl, C1-C6 alkoxy, hydroxycarbonyl, C1-C6 alkoxycarbonyl, amino, C1-C6 alkylamino, aminocarbonyl, C1-C6 alkylaminocarbonyl, C3-C8 cycloalkyl, a 5- to 10-membered heterocyclyl, C6- C10 aryl and a 5- to 10-membered heteroaryl; R3 and R4 independently of one another represent hydrogen or C1-C6 alkyl; R5 and R6 independently of one another represent hydrogen or C1-C6 alkyl; and R7 represents a 3- to 12- membered carbocyclyl, whereby the carbocyclyl can be substituted with 0, 1, 2, 3, 4 or 5 substituents independently of one another, selected from the group comprising halogen, hydroxy, C1-C6 alkyl and C1-C6 alkoxy. The invention also relates to a method for producing said pyrroles, to their use for the treatment and/or prophylaxis of diseases, in addition to their use for producing medicaments for the treatment and/or prophylaxis of diseases, notably to their use as antiviral agents, in particular against cytomegaloviruses.

L'invention concerne des pyrroles substitués de formule (I), dans laquelle R?1¿ signifie -OR?8¿ ou -NR?9¿R?10 ¿; R?2¿ désigne hydrogène, alkyle C¿1?-C¿6? ou aryle, R?2¿ pouvant être substitué comme alkyle avec 0, 1, 2 ou 3 substituants R?2-1 ¿indépendamment l'un de l'autre, sélectionnés dans le groupe comprenant halogène, hydroxy, alcoxy C¿1?-C¿6?, hydroxycarbonyle, alcoxycarbonyle C¿1?-C¿6?, alkylcarbonyloxy C¿1?-C¿6?, amino, alkylamino C¿1?-C¿6?, aminocarbonyle, alkylaminocarbonyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿8?, hétérocyclyle à 5 à 10 éléments, aryle C¿6?-C¿10?, phénoxy et hétéroaryle à 5 à 10 éléments, R?2¿ pouvant être substitué comme aryle avec 0, 1, 2 ou 3 substituants R?2-2 ¿indépendamment l'un de l'autre, sélectionnés dans le groupe comprenant halogène, hydroxy, nitro, cyano, trifluorométhyle, trifluorométhoxy, alkyle C¿1?-C¿6?, alcoxy C¿1?-C¿6?, hydroxycarbonyle, alcoxycarbonyle C¿1?-C¿6?, amino, alkylamino C¿1?-C¿6?, aminocarbonyle, alkylaminocarbonyle C¿1?-C¿6?, cycloalkyle C¿3?-C¿8?, hétérocyclyle à 5 à 10 éléments, aryle C¿6?-C¿10? et hétéroaryle à 5 à 10 éléments ; R?3¿ et R?4¿ représentent indépendamment l'un de l'autre hydrogène ou alkyle C¿1?-C¿6?; R?5¿ und R?6¿ représentent indépendamment l'un de l'autre hydrogène ou alkyle C¿1?-C¿6 ?; R?7¿ désigne carbocyclyle à 3 à 12 éléments, carbocyclyle pouvant être substitué avec 0, 1, 2, 3, 4 ou 5 substituants indépendamment l'un de l'autre, sélectionnés dans le groupe comprenant halogène, hydroxy, alkyle C¿1?-C¿6 ?et alcoxy C¿1?-C¿6?. La présente invention porte également sur des procédés de production associés, sur l'utilisation de ces pyrroles pour traiter et/ou prévenir des maladies et pour préparer des médicaments destinés au traitement et/ou à la prophylaxie de maladies, notamment en tant qu'agents antiviraux, en particulier contre les cytomégalovirus.
