  Synthesis and antibacterial activity of novel 4-pyrrolidinylthio carbapenems—I. 2-alkoxymethyl derivatives

  摘要：

  The synthesis and in vitro antibacterial activity of a novel series of 2-alkoxymethyl-4-pyrrolidinylthio-1 beta-methyl carbapenems are described. As a result of these studies, we discovered that FR27743 (19j) containing a novel,2-fluoroethoxymethyl substituent possesses a broad spectrum of antibacterial activity against both Gram-positive and Gram-negative organisms, including Pseudomonas aeruginosa. Furthermore, FR27743 exhibited excellent stability against renal dehydropeptidase-I (DHP-I), good urinary recovery, and superior in vivo activity compared to that for Meropenem against several systemic infections.
