The Influence of 2,4-Diamino-6-Hydroxypyrimidine and Food Restriction on Tetrahydrobiopterin Metabolism, Neurotransmitters and Behaviour in the Rat

Pteridines, 1991
Administration of 2,4-diamino-6-hydroxypyrimidine (DAHP) in the diet of rats reduced total biopterins in plasma, brain and liver. The levels of dihydropteridine reductase (DHPR) and the rate of biopterin biosynthesis were unaffected.
