Disclosed is a novel oxazolidinone derivative, particularly a novel oxazolidinone compound with a cyclic amidoxime or cyclic amidrazone group. Also disclosed is a pharmaceutical antibiotic composition including a novel oxazolidinone derivative, in vivo hydrolysable ester thereof, in vivo hydrolysable phosphate ester thereof, an isomer thereof or a pharmaceutically acceptable salt thereof as an effective ingredient. Because the novel oxazolidinone derivative, in vivo hydrolysable ester thereof, in vivo hydrolysable phosphate ester thereof, an isomer thereof or a pharmaceutically acceptable salt thereof exhibits a wide antibacterial spectrum against resistant bacteria, a low toxicity, and a strong antibacterial activity against Gram-positive and Gram-negative bacteria, it can be usefully used as an antibiotic.
