The present invention relates to novel oxazolidinone derivatives, their pharmaceutically acceptable salts and a process for the preparation thereof. More particularly, the present invention relates to oxazolidinone derivatives having pyridine or pyrimidine moeity substituted by heterocycle and heteroaromaticcycle at 4-position of phenyl ring. The compounds of the present invention have wide antibacterial spectrum, superior antibacterial activity and low toxicity, such that the compound of this invention can be used as an antibacterial agent.

group of linezolid was replaced with heteroaromatic ring substituted pyridine moiety, were newly synthesized, and their substituted effects on in vitro and in vivo antibacterialactivities were evaluated against four problematic gram-positive strains including drug resistant strains and two gram-negative strains. Most compounds exhibited the enhanced in vitro activities with 4-16-fold and three compounds
