The present invention relates to carbapenems and provides a compound of the formula (I)
wherein :
R1 is i-hydroxyethyl, 1-fluoroethyl or hydroxymethyl ;
R2 is hydrogen or C1-4alkyl;
R3 is hydrogen or C1-4alkyl;
A is a 5-membered heteroaryl ring containing one nitrogen atom and up to two additional heteroatoms selected from nitrogen, oxygen and sulphur ; and is bonded to the nitrogen of the linking carbamoyl group by a carbon atom in the ring, is substituted with the carboxy group on a carbon atom in the ring and is optionally further substituted on a carbon atom in the ring ; and
in any ring -NH-, H is optionally replaced by C1-4alkyl;
or a pharmaceutically acceptable salt or in vivo hydrolysable ester thereof. Processes for their preparation, intermediates in their preparation, their use as therapeutic agents and pharmaceutical compositions containing them are also described.
