Cat.No. 0476 - 2,4-Diamino-6-hydroxypyrimidine | C4H6N4O | CAS No. 56-06-4
Description: Inhibits tetrahydrobiopterin synthesis and thus NOS activity
Purity: ≥99% (HPLC)
Literature (1)

Biological Activity

GTP cyclohydrolase I (GCH1) inhibitor. Prevents the de novo synthesis of tetrahydrobiopterin (BH4) and thus suppresses the activity of NO synthase. Exhibits more potent inhibition of GCH1 in the presence of GFRP (GTP cyclohydrolase feedback-regulatory protein).

Technical Data

M. Wt 126.12
Formula C4H6N4O
Storage Desiccate at +4°C
Purity ≥99% (HPLC)
CAS Number 56-06-4
PubChem ID 2944
Smiles NC1=NC(N)=NC(O)=C1
