Compounds of the formula (I), or a pharmaceutically-acceptable salt, or an in-vivo-hydrolysable ester thereof, (I) R1a is NH(C═W)R
5
or (a); W is O or S; R
2
and R
3
are for example H or F; R
1
is for example hydrogen, or halogen; R
5
is selected from hydrogen, (2-6C)alkyl (optionally substituted); R
6
and R
7
are independently selected from hydrogen, and (1-4C)alkyl (optionally substituted); wherein R
4
is either a hydroxymethyl substituent on C-4′ of the isoxazoline ring; or R
4
is a hydroxymethyl substituent on C-5′ of the isoxazoline ring and the stereochemistry at C-5′ of the isoxazoline ring and at C-5 of the oxazolidinone ring is selected, such that the compound of formula (I) is a single diastereomer; are useful as antibacterial agents; and processes for their manufacture and pharmaceutical compositions containing them are described.
化合物的公式为(I),或其药学上可接受的盐,或其体内可水解的酯,其中(I) R1a为NH(C═W)R5或(a);W为O或S;R2和R3例如为H或F;R1例如为氢或卤素;R5选择自氢、(2-6C)烷基(可选取取代基);R6和R7独立选择自氢和(1-4C)烷基(可选取取代基);其中R4为在异氧杂环环的C-4'上的羟甲基取代基;或R4为在异氧杂环环的C-5'上的羟甲基取代基,并且异氧杂环环的C-5'和噁唑烷环的C-5的立体化学被选择,使得公式(I)的化合物是单一对映体。这些化合物作为抗菌剂有用,并且描述了制造它们的过程以及含有它们的制药组合物。
