  A series of 1 beta-methylcarbapenems containing variously C-2 substituted thiazol-2-ylthio groups were synthesized, and their in vitro anti-MRSA activity was examined. Among them, 1 beta-methyl-2-(4-arylthiazol-2-ylthio) carbapenems exhibited superior anti-MRSA activity. Introduction of a cationic moiety in the C-2 side chain not only reduced the binding to HSA but also increased the stability against DHP-I, without affecting the anti-MRSA, activity. It was also found that the distance between the cationic moiety and the carbapenem skeleton was related to the strength of HSA binding and the stability against DHP-I. (C) 1997 Elsevier Science Ltd.

  Discovery of novel antimicrobial agents effective against infections caused by drugresistant pathogens is an important objective. In order to find a new parenteral carbapenem antibiotic, which has potent antibacterial activity especially against methicillin-resistant staphylococci, vancomycin-resistant enterococci and penicillin-resistant Streptococcus pneumoniae, a series of 1β-methylcarbapenems with thiazol-2-ylthio groups at the C-2 position have been synthesized. Structure-activity relationships were investigated which led to SM-197436 (27), SM-232721 (44) and SM-232724 (41), being selected for further evaluation.

  An efficient synthesis of 1β-methylcarbapenem from the 1-(2-oxoazetidinyl)acetate 8 was developed by application of the Dieckmann reaction. Dieckmann-type cyclization of 8 and conversion to the enolphosphate 10 were achieved without epimerization to the 1α-methyl isomer in a one-pot procedure. Treatment with the mercaptan 22 after the phosphorylation resulted in a practical one-pot preparation of the 1β-methylcarbapenem derivative 23 from 8.
