Decreased conversion of tyrosine to catecholamines in the brain of rats treated with p-chlorophenylalanine

Abstract
Repeated treatment with p-chlorophenylalanine (100 mg kg−1) daily for 5 days impairs the transport of amino-acids from plasma into the brain and decreases the rate of conversion of [3H]tyrosine to [3H] catecholamines in the rat brain. The possible mechanisms involved are discussed.
