The potential of antiepileptic drugs (AEDs) to inhibit the water transport properties of Aquaporin 4 (AQP4) was investigated using a combination of in silico and in vitro screening methods. Virtual docking studies on 14 AEDs indicated a range of docking energies that spanned approximately 40 kcal/mol, where the most stabilized energies were consistent with that of the previously identified AQP4 inhibitor acetazolamide. Nine AEDs and one bio-active metabolite were further investigated in a functional assay using AQP4 expressing Xenopus oocytes. Seven of the assayed compounds were found to inhibit AQP4 function, while three did not. A linear correlation was indicated between the in silico docking energies and the in vitro AQP4 inhibitory activity at 20 mu M. (C) 2007 Elsevier Ltd. All rights reserved.
