The invention provides a novel oxazolidinone derivative represented by the formula (I):
wherein
Ring A is optionally substituted or fused and represents
(A-1) at least 7-membered monocyclic hetero ring containing at least three N atoms; (A-2) at least 6-membered monocyclic hetero ring containing at least two N atoms and at least one O atom; or (A-3) at least 7-membered monocyclic hetero ring containing at least two N atoms and at least one S atom;
X1 is a single bond, -O-, -S-, -NR2-, -CO-, -CS-, - CONR3-, -NR4CO-, -SO2NR5-, and -NR6SO2- (wherein R2 - R6 are independently hydrogen or lower alkyl), or lower alkylene or lower alkenylene in which one of the preceding groups may intervene;
Ring B is optionally substituted carbocycle or optionally substituted heterocycle;
R1 is hydrogen, or an organic residue which is able to bind to the 5-position of oxazolidinone ring in oxazolidinone antimicrobial agent,
and an antibacterial agent containing the same.
