The invention relates to antibacterial compounds of formula I n n n n n n n n n n wherein is a bond or is absent, V is CH, CR 6 or N; R 0 is H or, if is a bond, may also be alkoxy; R 1 is notably H or halogen; U is CH or N when is a bond, or, if is absent, U is CH 2 , NH or NR 9 ; R 2 is H, alkylcarbonyl or —CH 2 —R 3 ; R 3 is H, alkyl or hydroxyalkyl; R 4 is H or, if n is not 0 and R 5 is H, may also be OH; R 5 is H, alkyl, hydroxyalkyl, aminoalkyl, alkoxyalkyl, carboxy or alkoxycarbonyl; R 6 is hydroxyalkyl, carboxy, alkoxycarbonyl or —(CH 2 ) q —NR 7 R 8 , q being 1, 2 or 3 and each of R 7 and R 8 independently being H or alkyl or R 7 and R 8 forming with the N atom bearing them a ring; R 9 is alkyl or hydroxyalkyl; A is —(CH 2 ) p —, —CH 2 CH 2 CH(OH)— or —COCH 2 CH(OH)—; G is substituted phenyl or G 1 or G 2 n n n n n n n n n n wherein Q is O or S and X is CH or N; and Y 1 , Y 2 and Y 3 may each be CH or N; and n is 0 when A is —CH 2 CH 2 CH(OH)— or —COCH 2 CH(OH)—, and n is 0, 1 or 2 when A is —(CH 2 ) 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. |
