Abstract

Glycerol monolaurate (GML) is a naturally occurring surfactant that is used widely as an emulsifier in the food and cosmetics industries and is generally regarded as lacking in important biological activities. The recent observation that it inhibits the production of staphylococcal toxic shock toxin-1 (P. M. Schlievert, J. R. Deringer, M. H. Kim, S. J. Projan, and R. P. Novick, Antimicrob. Agents Chemother. 36:626-631, 1992) is therefore rather surprising and raises the interesting question of how such a compound might interact with cells. In this report, we show that GML inhibits the synthesis of most staphylococcal toxins and other exoproteins and that it does so at the level of transcription. We find that GML blocks the induction but not the constitutive synthesis of beta-lactamase, suggesting that it acts by interfering with signal transduction.

  • Glycerol monolaurate inhibits the production of staphylococcal toxic shock toxin-1 and the expression of virulence factors including protein A, alpha-hemolysin, β-lactamase, and the induction of vancomycin resistance in Enterococcus faecalis by interfering with signal transduction.

    “GML also inhibits the production of staphylococcal toxic shock toxin-1 effectively and the expression of virulence factors including protein A, alpha-hemolysin, β-lactamase, and the induction of vancomycin resistance in Enterococcus faecalis by interfering with signal transduction (Projan et al., 1994; Ruzin and Novick, 2000).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
