Distribution and dynamics of adamantanes in a lipid bilayer.

ABSTRACT: The adamantanes are a class of compounds that have found use in the treatment of influenza A and Parkinson's disease, among others. The mode of action for influenza A is based on the adamantanes' interaction with the transmembrane M2 channel, whereas the treatment of Parkinson's disease is thought to relate to a channel block of N-methyl-D-aspartate receptors. An understanding of how these compounds interact with the lipid bilayer is thus of great interest. We used molecular-dynamics simulations to calculate the potential of mean force of adamantanes in a lipid bilayer. Our results demonstrate a preference for the interfacial region of the lipid bilayer for both protonated and deprotonated species, with the protonated species proving significantly more favorable. However, the protonated sp
