This invention relates to new oxazolidinones having a cyclopropyl moiety, which are effective against aerobic and anerobic pathogens such as multi-resistant
staphylococci, streptococci
and
enterococci, Bacteroides
spp.,
Clostridia
spp. species, as well as acid-fast organisms such as
Mycobacterium tuberculosis
and other mycobacterial species.
The compounds are represented by structural formula I:
its enantiomer, diastereomer, or pharmaceutically acceptable salt or ester thereof.
Novelantibacterial biaryl oxazolidinones bearing an aza-, an oxa-, or a thiabicyclo[3.1.0]hex-6-yl ring system were synthesized, and their in vitro antibacterialactivity and structure-activity relationships (SAR) were evaluated. Most of the synthesized biaryl bicyclo[3.1.0]hex-6-yl oxazolidinones showed good antibacterialactivity against the Gram-positive and -negative bacteria tested. Regarding
