摘要

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 fluor o, chloro, bromo and iodo), trifluoromethyl, cyano, nitro, -COOH, -CONH2, -COOR A, -NHCORA, -CONHRA, -NHRA, -NRARB, or -CONRARB wherein RA and RB are independently a (C1-C6)alkyl group, and ALK represents a straight or branche d 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.
