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

Soluble in DMSO
>99 %
Desiccate at +4°C
