摘要

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 5-membered heteroaryl ring containing 2 to 4 heteroatoms independently selected from N, O and S; Q is selected from, for example, formulae (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 group of formula (TC5) wherein Rc is, for example, R13CO-, R13SO2- or R13CS-; wherein R13 is, for example, optionally substituted (1-10C)alkyl or R14C(O)O(1-6C)alkyl wherein R14 is optionally substituted (1-10C)alkyl; are useful as antibacterial agents; and processes for their manufacture and pharmaceutical compositions containing them are described.
