Compounds of formula (I), or a pharmaceutically-acceptable salt, or an in-vivo- hydrolysable ester thereof, wherein, for example, X is -O- or -S-; HET is an optionally substituted C-linked 6-membered heteroaryl ring containing 1 or 2 N atoms; Q is selected from, for example, (Q1) and (Q2); R2 and R3 are independently hydrogen or fluoro; T is selected from a range of groups, for example, an N-linked (fully unsaturated) 5-membered heteroaryl ring system or a 3,6-dihydro-(2H)-pyran-4-yl group or a 4-substituted piperazino group; are useful as antibacterial agents; and processes for their manufacture and pharmaceutical compositions containing them are described.

L'invention concerne des composés représentés par la formule (I), ou un sel pharmaceutiquement acceptable ou un ester de ceux-ci pouvant être hydrolysé in vivo. Dans la formule, par exemple, X est -O- ou -S-; HET est un système cyclique hétéroaryle à 6 chaînons et à liaison C éventuellement substitué contenant 1 ou 2 atomes N; Q est sélectionné, par exemple, entre Q1 et Q2. R?2¿ et R?3¿ sont indépendamment hydrogène ou fluoro; T est sélectionné dans le groupe comprenant, par exemple, un système cyclique hétéroaryle à 5 chaînons (complètement insaturé) à liaison N, un groupe 3,6-dihydro-(2H)-pyrane-4-yle, et un groupe pipérazino substitué en 4. Les composés sont utiles comme agents antibactériens. Des procédés de fabrication de ces composés sont décrits, ainsi que des compositions pharmaceutiques contenant ceux-ci.
