| abstract |
The invention relates to antibacterial compounds of formula (I), wherein R 1 is H, halogen, (C 1 -C 3 )alkyl or (C 1 -C 3 )alkoxy; R 2 is H, halogen, (C 1 -C 3 )alkyl, (C 1 -C 3 )alkoxy or pyrrolidin-1-yl; R 3 is H, halogen, (C 1 -C 3 )alkyl, (C 1 -C 3 )alkoxy, vinyl or 2-methoxycarbonyvinyl or R 2 and R 3 together with the two carbon atoms which bear them form a phenyl ring; R 4 is H, halogen, (C 1 -C 3 )alkyl or (C 1 -C 3 )alkoxy; and R 5 is H, (C 1 -C 3 )alkyl or cyclopropyl, or R 4 and R 5 form together a —CH 2 CH 2 CH 2 — group; A is the divalent group —CH 2 —, —CH 2 CH 2 —, #—CH(OH)CH 2 —*, #—CH 2 N(R 6 )—* and —CH 2 NHCH 2 —, wherein # indicates the point of attachment to the optionally substituted (quinazoline-2,4-dione-3-yl)methyl residue and * represents the point of attachment to the substituted (oxazolidinon-4-yl)methyl residue; R 6 is H or acetyl; Y is CH or N; and Q is O or S; and salts of such compounds. |
