Description and Uses

2,4-Diamino-6-hydroxypyrimidine (DAHP) is a selective, specific inhibitor of GTP cyclohydrolase I, the rate limiting step for de novo pterin synthesis. In HUVEC cells, the IC₅₀ for inhibition of BH₄ biosynthesis is about 0.3 mM. DAHP can be used to effectively block NO production in several cell types.
