Capturing the Molecular Mechanism of Anesthetic Action by Simulation Methods.

Significant computational efforts have been focused toward exposing the molecular mechanisms of anesthesia in recent years. In the past decade, this has been aided considerably by a momentous increase in the number of high-resolution structures of ion channels, which are putative targets for the anesthetic agents, as well as advancements in high-performance computing technologies. In this review, typical simulation methods to investigate the behavior of model membranes and membrane-protein systems are briefly reviewed, and related computational studies are surveyed. Both lipid- and protein-mediated mechanisms of anesthetic action are scrutinized, focusing on the behavior of ion channels in the latter case.
