5-Aminoimidazole-4-carboxamide

5-Aminoimidazole-4-carboxamide ribotide

C4H6N4O (126.0542)

5-Aminoimidazole-4-carboxamide is an imidazole derivative which is a metabolite of the antineoplastic agents BIC and DIC. By itself, or as the ribonucleotide, it is used as a condensation agent in the preparation of nucleosides and nucleotides. Compounded with orotic acid, it is used to treat liver diseases. -- Pubchem.

2,4-Diamino-6-hydroxypyrimidine

2,6-diamino-1,4-dihydropyrimidin-4-one

C4H6N4O (126.0542)

2,4-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). 2,4-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).
