We discovered an orally active carbapenem, L-084, through pharmacokinetic studies on various prodrug esters of (1R,5S,6S)-6-[(R)-1-hydroxyethyl]-1-methyl- 2-[1-(1,3-thiazolin-2-yl)azetidin-3-yl]thio-1-carbapen-2-em-3-carboxylic acid (LJC11,036). L-084 showed a strong antimicrobial activity against Gram-positive and Gram-negative bacteria and exhibited the highest intestinal absorption among synthesized prodrugs of LJC11,036.

Carbapenem-3-carboxylic acid ester derivatives
-
, (2008/06/13)
Disclosed are carbapenem-3-carboxylic acid ester derivatives of formula (I), wherein R1 is a hydrogen atom or a lower alkyl group, R2 is an alkyl group which may be substituted by a cycloalkyl group having about 4 to 7 carbon atoms and which may be substituted by a lower alkyl group, or is a cycloalkyl group having 4 to 7 carbon atoms which may be substituted by a lower alkyl group and n is 0 or 1. The compounds are highly absorbable through the digestive tract and are rapidly converted in the body to the active compound, which shows strong antibacterial activity. STR1
