| Research Abstract |
Apart from the conventional mechanism in which anesthetics specifically bind to receptors and channels, we reverified the mechanistic hypothesis that anesthetics may interact with biomembranes to exert clinically useful and adverse effects based on the latest structural and functional theory about biomembranes. The relevance of membrane lipid rafts to anesthetics was questionable at least in their effects on raft-like model membranes. However, anesthetics structure-dependently interacted with biomimetic membranes consisting of specific lipids (cholesterol and anionic phospholipids) and their interacting potencies were discriminated even between stereoisomers. These results support the membrane interaction of anesthetics as the mode of action.
