8-Hydroxyguanine

1H-Purine-6,8-dione, 2-amino-7,9-dihydro-1H-purine-6,8-dione

C5H5N5O2 (167.0443)


Formation of 8-hydroxyguanine (8-OHG), a mutagenic base which is a marker for OH-mediated DNA damage, requires peroxidase and halides and occurs in the presence of transition metal chelators (DTPA +/- desferrioxamine), and is inhibited by catalase, superoxide dismutase (SOD), and scavengers of hypohalous acids. (PMID 10820020). 8-Hydroxyguanine is an oxidative stress marker for diagnosis of Alzheimers disease (AD). (PMID 15977989).

2,8-Dihydroxyadenine

6-Amino-1H-purine-2,8(3H,7H)-dione

C5H5N5O2 (167.0443)


2,8-Dihydroxyadenine is a Purine metabolite usually not detectable in biofluids of normal individuals; this insoluble metabolite (at physiological urinary pH) cause urinary tract calculi and arthritis, and is identified in Adenine phosphoribosyltransferase deficiency (APRT, OMIM 102600). (PMID 16613999) In APRT, 2,8-dihydroxyadenine (DHA) accumulates in crystals within the tubular lumens (a feature of many kidney stone diseases) creating crystal-induced injury in human kidney epithelial cells. (PMID 16374038) Urinary DHA crystals are easily recognized under a microscope, and effective treatment can be offered and therefore the prognosis depends upon the renal function at diagnosis; treatment consists of adequate fluid intake, a low-purine diet and administration of allopurinol.

2,8-Dihydroxyadenine

C5H5N5O2 (167.0443)


A member of the class of 6-aminopurines that is adenine bearing two hydroxy substituents at positions 2 and 8. It is a highly insoluble metabolite of adenine that causes radiolucent urolithiasis. It is produced by individuals who suffer from adenine phosphoribosyltransferase (APRT) deficiency, a rare autosomal recessive error of purine metabolism.
