Stabilization of clathrin coated vesicles by amantadine, tromantadine and other hydrophobic amines

Abstract
Amantadine and related compounds stabilized the structure of purified pig brain clathrin coated vesicles (CCV) at biologically relevant concentrations. Incubation of purified CCV for 30 min at 25°C or 37°C caused the release clathrin, as determined by a centrifugation assay, and a reduction in the number of coated vesicles, by electron microscopy. Amantadine (10 mM), tromantadine (1 mM), amidine D295 (cyclohexylcarboximidamide-(N-benzyl)hydrochloride) (10 mM), chloroquin (0.1 mM) and monodansyleadaverine (10 mM) significantly reduced the extent of dissociation.
