Outer Membrane Permeability Enhancement

Molecular classification: Other

Overview

Outer membrane permeability enhancement refers to strategies or mechanisms that increase the permeability of the outer membrane (OM) of Gram-negative bacteria. The OM acts as a selective barrier, protecting bacteria from harmful agents, including antibiotics, by limiting their entry into the cell. Enhancing OM permeability is a key approach in overcoming bacterial resistance and improving antibiotic efficacy. Mechanisms include disruption via polycations/chelators and efflux pump inhibition.

Mechanism of action

Disruption of outer membrane integrity via LPS interaction or efflux pump inhibition, leading to increased antibiotic permeability.
