1Beta-methylcarbapenems having various 3,5-disubstituted pyrrolidinylthio-side chains at C-2 were designed and synthesized. Evaluation of their antibacterial activities indicated that J-111,347 (1a) is the first example of an extremely broad spectrum antibiotic showing activity against methicillin-resistant Staphylococcus aureus (MRSA) as well as Pseudomonas aeruginosa.
