Compounds of formula (I)
or a pharmaceutically-acceptable salt, or an in-vivo-hydrolysable ester thereof, wherein, for example, 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, Q3 and Q5; 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.
                            化合物的公式(I)或其药学上可接受的盐或其体内
水解酯,其中,例如,HET是一个可选取的含有2-4个杂原子(独立选择自N、O和S)的C-连接的5元杂环芳基环;Q选自Q3和Q5等;R2和R3独立地是氢或
氟;T选自一系列基团,例如,一个N-连接的(完全不饱和的)5元杂环芳基环系统或一个公式为(TC5)的基团:其中Rc是例如R13CO—、R13SO2—或R13CS—;其中R13是例如可选取的取代的(1-10C)烷基或R14C(O)O(1-6C)烷基,其中R14是可选取的取代的(1-10C)烷基;它们可用作抗菌剂;并描述了制造它们的过程和含有它们的制药组合物。
