  • Title: The interaction of local anesthetics with lipid membranes.
    Author: Zapata-Morin PA, Sierra-Valdez FJ, Ruiz-Suárez JC.
    Journal: J Mol Graph Model; 2014 Sep; 53():200-205. PubMed ID: 25181454.
    Abstract:
    Molecular Dynamic Simulations are performed to evaluate the interaction of lidocaine, procaine and tetracaine with a lipid membrane. The main interest is to evaluate the structural changes produced by these local anesthetics in the bilayers. Penetration trajectories, interaction energies, entropy changes and an order parameter are calculated to quantify the destabilization of the lipid configurations. We show that such structural parameters give important information to understand how anesthetic agents influence the structure of plasma membranes. Graphic processing units (GPUs) are used in our simulations.
