Structural analysis of compounds with actions similar to local anesthetics and antipsychotic phenothiazines in yeast

Abstract

Local anesthetics and antipsychotic phenothiazines cause a rapid shutdown of both actin polarization and translation initiation in yeast cells, like some environmental stresses. These compounds all have an amphiphilic structure, surfactant activity and the ability to lyse yeast cells. To elucidate the structures responsible for the shutdown activity and cell lysis, we investigated a variety of amphiphiles. In the hydrophobic region, the straight alkyl structure was sufficient for the shutdown of actin polarization and translational initiation. In the hydrophilic region of the straight alkyl compounds, cationic trimethyl ammonium (TMA) and non‐ionic hydroxyl structure (alcohols) shut down both reactions, while an anionic structure, sulphate, with a long alkyl chain (≥C6) shut down actin polarization only. On the compounds that shut down both reactions, including the clinical drugs, TMA compounds and alcohols, the potencies of shutdown and lysis exponentially increased with increasing the number of carbons in the hydrophobic region, whereas safety was affected by the structures of both hydrophilic and hydrophobic regions. These results indicate that the yeast system can easily evaluate clinical drugs, and provide a structural basis for designing compounds to shut down intracellular reactions.

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.
