Its phosphonate analog 17, however, was neither a significant antibacterial agent nor a good beta-lactamase inhibitor. Chemical combinations of trans carbapenem 13 with cis carbapenem 6 (compound 19) as well as clavulanic acid (20) with cis carbapenem 6 (compound 22) via a tetrachloroethane linker exhibited remarkable activity against beta-lactamase producing microorganisms in vitro.
