Local Anesthetics, Antipsychotic Phenothiazines, and Cationic Surfactants Shut Down Intracellular Reactions through Membrane Perturbation in Yeast

Abstract

High osmolarity and glucose deprivation cause rapid shutdowns of both actin polarization and translation initiation in yeast. Like these stresses, administration of local anesthetics and of antipsychotic phenothiazines caused similar responses. All these drugs have amphiphilic structures and formed emulsions and permeabilized the cell membrane, indicating that they have the same features as a surfactant. Consistently with this, surfactants induced responses similar to those of local anesthetics and phenothiazines. Benzethonium chloride, a cationic surfactant, showed a more potent shutdown activity than phenothiazines, whereas SDS, an anionic surfactant, transiently depolarized actin without inhibiting translation initiation, suggesting that a cationic charge in the amphiphile is important to the shutdown of both reactions. The clinical drugs and the cationic surfactants at low concentrations caused shutdown without membrane permeabilization, suggesting that these compounds and stresses activate shutdown, via perturbation rather than disruption of the cell membrane.

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.
