Understanding how this tiny molecule kills yeast is hence important for guiding improvement of derivatives with an improved therapeutic index and other resistance-refractory antimicrobial agents. In the widely accepted ion channel model for its mechanism of cytocidal action, amphotericin forms aggregates inside lipid bilayers that permeabilize and kill cells. In contrast, we report that amphotericin exists mostly inside the kind of massive, extramembranous aggregates that kill yeast by extracting ergosterol from lipid bilayers. These findings reveal that extraction of a polyfunctional lipid underlies the resistance-refractory antimicrobial action of amphotericin and suggests a roadmap for separating its cytocidal and membrane-permeabilizing activities. This new mechanistic understanding is also guiding improvement of the first derivatives of amphotericin that kill yeast but not human cells.Users may view, print, copy, and download text and data-mine the content material in such documents, for the purposes of academic research, topic often to the full Circumstances of use:http:natureauthorseditorial_policieslicense.html#terms Correspondence and requests for materials should be addressed to C.M.R.
