Antibacterial agents have the formula (I) or are pharmaceutically acceptable salts or in vivo hydrolysable esters thereof:
in which Y¹ is oxygen, sulphur or -CH₂ and Z represents hydrogen, halogen, C1-4 alkoxy, -CH₂-Q or -CH=CH-Q where Q represents hydrogen, halogen, hydroxy, mercapto, cyano, carboxy, carboxylic ester, C1-4 alkyloxy, acyloxy, aryl, a heterocyclyl group bonded via carbon, a heterocyclylthio group or a nitrogen containing heterocyclic group bonded via nitrogen;
R⁵ represents phenyl, substituted phenyl, cyclohexenyl, cyclohexadienyl or an optionally substituted 5 or 6-membered heterocyclic ring containing up to three hetero atoms selected from oxygen, sulphur or nitrogen, R⁶ is hydrogen, hydroxymethyl, formamido, or methoxy, R⁷ and R⁸ are the same or different and represent hydrogen, C1-6 alkyl, substituted C1-6 alkyl, halogen, amino, phenyl, substituted phenyl, hydroxy or C1-6 alkoxy or R⁷ and R⁸ form the residue of an optionally substituted 5 or 6- membered carbocyclic ring or a 5 or 6-membered heterocyclic ring containing up to three hetero atoms selected from oxygen, sulphur or nitrogen, R⁹ is
wherein R¹⁰ and R¹¹ are the same or different and each represents hydroxy, or protected hydroxy and XR⁹ is -(CH₂)nR⁹, -NHCOR⁹, -N=CHR⁹, -NHCH₂R⁹, or -COR⁹, where n is from 0 to 2; with the proviso that XR⁹ does not represent -N=CHR⁹ when R⁶ represents hydrogen.
The use of the compounds is described together with intermediates for their preparation.
