| abstract |
This invention provides novel oxazolidinone derivatives represented by chemical Formula (I), or pharmaceutically acceptable salts thereof: wherein X is NR1, CR2R3, O, S, SO, or SO2; and Z is NR4, S, SO, SO2 or O. The compounds are useful antimicrobial agents, effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria such as multiply-resistant staphylococci and streptococci, as well as anaerobic organisms such as bacteroides and clostridia species, and acid-fast organisms such as Mycobacterium tuberculosis and Mycobacterium avium. |
