Lenapenem is an anti-bacterial agent that was tested in late 90's in phase II clinical trials against bacterial infections. Lenapenem was shown to be active against both Gram-positive and Gram-negative bacteria and exerted its therapeutic effect by inhibiting penicillin binding proteins. The development of the drug was terminated due to the safety reason.
