Abstract
The synthesis and in vitro antimicrobial activity of a new synthetic carbapenem, (5R, 6S)-6-[(R)-1-hydroxyethyl]-2-[(S)-l-acetimidoylpyrrolidin-3-ylthio]-l-carbapen-2-em-3-carboxylic acid (RS-533), are described. The MIC values of related penems and carbapenems are also given for comparison with those of the new carbapenem.
