Carbapenem antibacterial compounds, compositions containing such compounds and methods of treatment

Compounds of formula I are disclosed. ##STR1## as well as pharmaceutically acceptable salts thereof. The naphthosultam is substituted with various substituent groups including at least one cationic group -A-Q-L-B. The carbapenems of the invention are effective against susceptible bacterial organisms, including methicillin resistant Staphylococcus aureus (MRSA), methicillin resistant Staphylococcus epidermidis (MRSE), and methicillin resistant coagulase negative Staphylococci (MRCNS).

Carbapenem antibacterial compounds, compositions containing such

Carbapenems substituted with a naphthosultam at position 2 and linked through a CH.sub.2 group are disclosed. Pharmaceutical compositions and methods of treatment are also included. The naphthosultam is substituted with at least one cationic group --A--Q--L--B. ##STR1## A--Q--L--B represents a side chain wherein in part: A is a C.sub.1-6 alkylene group, straight or branched, and optionally interrupted or terminated by 1-2 of --O--, --S--, NR.sup.a --, --C(O)-- and CH.dbd.CH--

3-aryl of heteroaryl-7-heteroaralkylamido cephalosporin compounds,

Disclosed are carbapenems of the formula ##STR1## which are 2-(9-fluorenonyl)-carbapenems useful as antibacterial agents. Intermediates for preparation of these compounds is also disclosed.

2-(9-fluorenonyl)-carbapenem intermediates

Carbapenems of the formula ##STR1## are useful intermediates in the preparation of 2-(9-fluorenonyl)-carbapenem antibacterial agents.

##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are, inter alia, independently selected from the group consisting of hydrogen, alkyl, aryl, and aralykl. Such compounds as well as their pharmaceutically acceptable salt, ester and amide derivatives are useful as antibiotics. Also disclosed are processes for the preparation of such compounds, pharmaceutical compositions comprising such compounds and methods of treatment comprising administering such compounds and compositions when an antibiotic effect is indicated.

Process for preparing 1-carba-2-penem-3-carboxylic acid

Carbapenems of the formula ##STR1## wherein either the 2-fluoren-9-one or 3-fluoren-9-one is attached at the 2-position of the carbapenem are useful antibacterial agents.
