In this paper the process of α-tocopherol (TCP) passing across DPPC membrane was simulated using both the potential of mean force (PMF) and the accelerated molecular dynamics (aMD) methods, respectively. Energy properties, hydrogen bonds and orientation have been compared between these two methods and several conclusions have been obtained. The results indicate that TCP tends to stay at z = 1.2 nm of lipid bilayer. The binding free energy profiles of these two methods are alike. All these show that aMD could obtain comparable results as PMF method, while needs less computation time and resources. Therefore, aMD method could be used as an alternative method for prediction of transport properties of drug-lipid system.
