Mechanism of Action

Targets/IC₅₀/Ki	AmpC β-lactamase
In vitro	Imipenem, a β-lactam antibiotic, binds to penicillin binding protein 2 with the highest affinity and produces rounded cells. The binding of this compound causes cells to lyse quickly and thereby to release less free endotoxin.
In vivo	Imipenem has a very short half-life. This compound has antimycobacterial activity both in a mouse model and in humans at high risk for failure of treatment for MDR (multiple-drug-resistant) tuberculosis.
