Chemical Information
FooDB Name2,4-Diamino-6-hydroxypyrimidine
Description2,4-Diamino-6-hydroxypyrimidine (DAHP) is a selective inhibitor of GTP cyclohydrolase I (GTPCH) that restricts the de novo synthesis of tetrahydrobiopterin (BH4) or the BH4 precursor in vascular smooth muscle cells (VSMC). (PMID 12883322) 2,4-Diamino-6-hydroxypyrimidine also inhibits nitric oxide (NO) in both Interferon-gamma (IFN-gamma) and antigen (Ag)/IgE (Ag/IgE) systems, increasing Mast cells (MC) degranulation. (PMID 14514683) Sepiapterin, a precursor to tetrahydrobiopterin in the salvage pathway, completely reverses the effect of 2,4-diamino-6-hydroxypyrimidine on neuronal NO-synthase (nNOS) ubiquitylation. (PMID 16216381) [HMDB]
