Compounds of the formula (I), or a pharmaceutically-acceptable salt, or an in-vivo-hydrolysable ester thereof, (I) R1a is NH(C=W)R5 or (a); W is O or S; R2 and R3 are for example H or F; R1 is for example hydrogen, or halogen; R5 is selected from hydrogen, (2-6C)alkyl (optionally substituted); R6 and R7 are independently selected from hydrogen, and (1-4C)alkyl (optionally substituted); wherein R4 is either a hydroxymethyl substituent on C-4' of the isoxazoline ring; or R4 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.
公式(I)的化合物,或其药学上可接受的盐,或其体内可水解的酯,(I)中R1a是NH(C=W)R5或(a);W是O或S;R2和R3例如是H或F;R1例如是氢或卤素;R5从氢,(2-6C)烷基(可选地取代)中选择;R6和R7独立地从氢和(1-4C)烷基(可选地取代)中选择;其中R4是异噁唑环的C-4'上的羟甲基取代基;或R4是异噁唑环的C-5'上的羟甲基取代基,且异噁唑环的C-5'和噁唑烷酮环的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;它们作为抗菌剂是有用的;并描述了它们的制备方法和含有它们的药物组合物。
