1 beta-Methyl-2-(5-substituted pyrrolidin-3-ylthio)carbapenems. 3. Synthesis and antibacterial activity of BO-2727 and its related compounds.
The synthesis and biological activity of (1R,5S,6S)-2-[(3S,5S)- 5-substituted pyrrolidin-3-ylthio]- 6-[(R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylic acid in which hydroxy-substituted aminoethyl, aminopropyl, and aminobutyl groups were introduced as substituents, are described. These derivatives showed potent antibacterial activity against Gram-positive and Gram-negative bacteria including P. aeruginosa. Among them, lenapenem (BO-2727, 7b), carrying an (R)-1-hydroxy-3-(N-methylamino)propyl group, was selected as a development candidate.
