Compounds of formula (I) are antibacterials: wherein R1 represents hydrogen, or C1-C6 alkyl or C1-C6 alkyl substituted by one or more halogen atoms; R2 represents a group R10-(X)n-(ALK)M- wherein R10 represents hydrogen, or a C1- C6 alkyl, C2-C6 alkenyl,C2-C6 alkynyl, cycloalkyl, aryl, or heterocyclyl group, any of which may be unsubstituted or substituted by (C1-C6) alkyl, (C1- C6) alkoxy, hydroxy, mercapto, (C1-C6) alkylthio, amino, halo (including fluoro, chloro, bromo and iodo), trifluoromethyl, cyano, nitro, -COOH, -CONH2, -COORA, -NHCORA, -CONHRA, -NHRA, -NRARB, or -CONRARB wherein RA and RB are independently a (C1-C6) alkyl group, and ALK represents a straight or branched divalent C1-C6 alkylene, C2-C6 alkenylene, or C2-C6 alkynylene radical, and may be interrupted by one or more non-adjacent -NH-, -O- or -S- linkages, X represents -NH-, -O- or -S-, and m and n are independently 0 or 1; and A represents a group as defined in the specification.

L'invention concerne des composés antibactériens selon la formule (I). Dans cette dernière, R?1¿ représente hydrogène, ou alkyle C¿1?-C¿6? ou alkyle C¿1?-C¿6? substitué par un ou plusieurs atomes d'halogène; R¿2? représente un groupe R¿10?-(X)¿n?-(ALK)¿m?- où R¿10? représente hydrogène, ou un groupe alkyle C¿1?-C¿6?, alkényle C¿2?-C¿6?, alkynyle C¿2?-C¿6?, cycloalkyle, aryle ou hétérocyclile; chacun pouvant être substitué ou non par alkyle (C¿1?-C¿6?), alcoxy(C¿1?-C¿6?), hydroxy, mercapto, alkylthio(C¿1?-C¿6?), amino, halo (y compris, fluoro, chloro, nromo et iodo), trifluorométhyle, cyano, nitro, -COOH, -CONH¿2?, -COOR?A¿, -NHCOR?A¿, -CONHR?A¿, -NHR?A¿, -NR?A¿R?B¿, ou -CONR?A¿R?B¿ où R?A¿ et R?B¿ sont indépendamment un groupe alkyle (C¿1?-C¿6?), et ALK représente un alkylène C¿1?-C¿6? divalent droit ou ramifié, alkénylène C¿2?-C¿6?, ou un radical alkynylène C¿2?-C¿6? et peut être interrompu par une ou plusieurs liaisons non adjacentes -NH-, -O- ou -S-, X représente -NH-, -O- ou -S- et m et n sont indépendamment 0 ou 1; et A représente un groupe tel que défini dans les spécifications.
