摘要:
                                The synthesis and biological activities of a series of new 1 beta -methylcarbapenems 1a-h having heteroaromatic thioether moiety at C-5 position of pyrrolidine were described. Among these compounds, 1,2,3-thiadiazole derivative 1h showed the most potent antibacterial activity and advanced pharmacokinetics in comparison with meropenem. (C) 2001 Elsevier Science Ltd.
