Abstract: A process for preparing a compound of the formula I: or pharmaceutical acceptable salts thereof wherein X is —NR1—, —S(O)g—, or —O—; R1 is —H, C1-6 alkyl optionally substituted with one or more —OH, —CN, or halo, or R1 is —(CH2)h-aryl, —COR1-1, —COOR1-2, —CO—(CH2)h—COR1-1, C1-6 alkyl sulfonyl, —SO2—(CH2)h-aryl, or —(CO)i-Het; R2 is —H, C1-6 alkyl, —(CH2)h-aryl, or halo; R3 and R4 are the same or different and are —H or halo; R6 is —H, C1-12 alkyl optionally substituted with one or more halo, C3-12 cycloalkyl, C1-6 alkoxy. The compounds are useful antimicrobial agents.

Abstract: The present invention provides compounds of formula I ##STR1## or a pharmaceutical acceptable salt thereof wherein Q, X, Y and R.sub.1 are as defined in the claims which are antibacterial agents.

Abstract: The present invention provides novel substituted amionphenyl isoxazoline derivatives of formula I ##STR1## wherein R.sub.1 is H, alkyl, cycloalkyl, alkoxy, amino, or alkylamino; X and Y are the same and different and are H, F, or CH.sub.3 ; W is O, or S;Q is a 4-, 5-, 6-, 7-, or 9-membered heterocyclic moiety containing one or more nitrogen, sulfur and/or oxygen. The compounds of the invention are useful as antimicrobial agents for preventing and treating infectious diseases.

Abstract: A process for preparing a compound of the formula I: ##STR1## or pharmaceutical acceptable salts thereof wherein X is --NR,--, --S(O).sub.g --, or --O--; R.sub.1 is --H, C.sub.1-6 alkyl optionally substituted with one or more --OH, --CN, or halo, or R.sub.1 is --(CH.sub.2).sub.h -aryl, --COR.sub.1-1, 13 COOR.sub.1-2, --CO--(CH.sub.2).sub.h --COR.sub.1-1, C.sub.1-6 alkyl sulfonyl, --SO.sub.2 --(CH.sub.2).sub.h -aryl, or --(CO).sub.i -Het; R.sub.2 is --H, C.sub.1-6 alkyl, --(CH.sub.2).sub.h -aryl, or halo; R.sub.3 and R.sub.4 are the same or different and are --H or halo; R.sub.5 is --H, C.sub.1-12 alkyl optionally substituted with one or more halo, C.sub.3-12 cycloalkyl, C.sub.1-6 alkoxy. The compounds are useful antimicrobial agents.

Abstract: The present invention provides compounds of formula 1 ##STR1## or pharmaceutical acceptable salts thereof wherein A and R.sub.1 are as defined in the claims which are antibacterial agents.

Abstract: This invention provides novel oxazolidinone derivatives represented by chemical Formula (I), or pharmaceutically acceptable salts thereof: ##STR1## wherein X is NR.sub.1, CR.sub.2 R.sub.3, O, S, SO, or SO.sub.2 ; and Z is NR.sub.4, S, SO, SO.sub.2 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.
