This compound was shown to be identical to a synthetic adduct prepared according to the procedure of Seto<jats:italic>et al. (Bull. Chem. Soc. Jpn. 58<\/jats:italic>, 3431\u20133435, 1985). The UV, NMR and other characteristics of the compound were consistent with the tricyclic pyrimidinopurine structure proposed by these investigators. Its endogenous origin is indicated by its presence in the urine of rats fed an MDA\u2010free diet, and by the observation that its excretion increased following iron or carbon tetrachloride administration. It may serve as a marker for nucleic acid modification caused by lipid peroxidation<jats:italic>in vivo<\/jats:italic>.<\/jats:p>","DOI":"10.1007\/bf02562209","type":"journal-article","created":{"date-parts":[[2007,2,8]],"date-time":"2007-02-08T02:11:18Z","timestamp":1170900678000},"source":"Crossref","is-referenced-by-count":42,"title":["Isolation of a guanine\u2010malondialdehyde adduct from rat and human urine"],"prefix":"10.1002","volume":"25","author":[{"given":"M.","family":"Hadley","sequence":"first","affiliation":[{"name":"Department of Nutritional Sciences, College of Biological Science University of Guelph Guelph Ontario N1G 2W1 Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
