title: d-Amphetamine binding to brain lipid.
abstract: The interaction of d-amphetamine with several brain tissue components has been investigated. A brain lipid extract and a number of individual phospholipids were found to bind d-amphetamine when measured by means of a hexane-buffer partition coefficient technique. Phosphatidylserine showed the greatest binding and phosphatidylethanolamine and dipalmitoyllecithin were also effective. Phospholipid binding of d-amphetamine was shown to be related to fatty acid composition. Cholesterol and ganglioside did not bind. It is suggested that phospholipid binding of d-amphetamine may play a role in the pharmacological action of this drug.
