24-Diamino-6-hydroxypyrimidine (DAHP) is a selective specific inhibitor of GTP cyclohydrolase I the rate limiting step for de novo pterin synthesis.

Methoxyamine HCl covalently binds to apurinic/apyrimidinic (AP) DNA damage sites and inhibits base excision repair (BER), which may result in an increase in DNA strand breaks and apoptosis.
