A is a C1-6 alkylene group, straight or branched, and optionally interrupted or terminated by 1-2 of —O—, —S—, NRa—, —C(O)— and —CH═CH—;
Q represents
in which:
b is 2 or 3;
and X− is a charge balancing group;
L represents a C1-8 alkylene group, unsubstituted or substituted with 1-3 Rc groups, and is interrupted or terminated by 1-3 of —CH═CH—, —C(O)—, —C(O)NRd—, —Het(Re)—, —C(O)—Het(Re)—, —C(O)NRa—Het(Re)—, —O—,—S—, —S(O)—, —SO2—, —CO2—, NRa—, —N+(Ra)2—
B represents
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).
