Tetraethylene glycol monooctyl ether

四聚乙二醇单辛醚,

Tetraethylene glycol monooctyl ether (TEGMOOE) is a surfactant and antimicrobial agent. It is a non-ionic surfactant that is used in many industrial applications, including as an emulsifier, dispersing agent, wetting agent, and defoamer. TEGMOOE has been shown to inhibit the multidrug efflux pump in some bacterial cells by binding to the signal peptide. This binding prevents the formation of an antibiotic-inhibitor complex with the enzyme cell wall synthesis that is required for cell wall biosynthesis, inhibiting protein synthesis and cell division. TEGMOOE also has been shown to have antimicrobial properties against tissue culture bacteria such as Staphylococcus aureus and Enterococcus faecalis. TEGMOOE can also be used as a calibration standard for titration calorimetry or flow systems by adding fatty acid to TEGMOOE solution
