The invention relates to antibacterial compounds of formula I wherein is a bond or is absent, V is CH, CR6 or N； R0 is H or, if is a bond, may also be alkoxy； R1 is notably H or halogen； U is CH or N when is a bond, or, if is absent, U is CH2, NH or NR9； R2 is H, alkylcarbonyl or -CH2-R3； R3 is H, alkyl or hydroxyalkyl； R4 is H or, if n is not 0 and R5 is H, may also be OH； R5 is H, alkyl, hydroxyalkyl, aminoalkyl, alkoxyalkyl, carboxy or alkoxycarbonyl； R6 is hydroxyalkyl, carboxy, alkoxycarbonyl or -(CH2)q-NR7R8, q being 1, 2 or 3 and each of R7 and R8 independently being H or alkyl or R7 and R8 forming with the N atom bearing them a ring； R9 is alkyl or hydroxyalkyl； A is -(CH2)p-, -CH2CH2CH(OH)- or -COCH2CH(OH)-； G is substituted phenyl or G1 or G2 wherein Q is O or S and X is CH or N； and Y1, Y2 and Y3 may each be CH or N； and n is 0 when A is -CH2CH2CH(OH)- or -COCH2CH(OH)-, and n is 0, 1 or 2 when A is -(CH2)p-, p being 1, 2, 3 or 4, with the proviso that the sum of n and p is then 2, 3 or 4； and to salts of such compounds.
