7-Methylguanine
7-Methylguanine is a metabolite of DNA methylation and depurination observed in normal human biofluids; however, it has been found significantly higher in the urine of smokers than in nonsmokers. (PMID 16059882). 7-Methylguanine has been identified in the human placenta (PMID: 32033212). 7-Methylguanine is a metabolite of DNA methylation and depurination observed in normal human biofluids; however, it has been found significantly higher in the urine of smokers than in nonsmokers. (PMID 16059882) [HMDB] KEIO_ID M043
3-Methylguanine
3-Methylguanine is a methylated purine base. Methylated purine bases are known to be present in normal urine and to change under pathological conditions, in particular in the development of leukemia, tumors and immunodeficiency, by the altered turnover of nucleic acids typical of these diseases.

1-Methylguanine
1-Methylguanine is a naturally occurring modified purine derived from tRNA, found in elevated levels in the serum and urine of cancer patients (PMID:2413515). Increase of 1-methylguanine in the urine of colorectal tumor bearing patients, has been justified either by a more rapid turnover of nucleic acids in tumor tissue or by an increase in the extent of their methylation (PMID:9069642). Present in Chinese cabbage (Brassica chinensis), and other plants
N2-Methylguanine
N2-Methylguanine is a modified nucleoside. N2-Methylguanine is an endogenous methylated nucleoside found in human fluids; methylated purine bases are present in higher amounts in tumor-bearing patients compared to healthy controls. Human exposure to carcinogenic alkylating agents can lead to the formation of covalently bound adducts in DNA, some of which are excreted in urine as alkylated purines following DNA degrdn. and repair; the N2 position of guanine is one of the major sites for DNA modification by various carcinogens. Measurements of RNA or DNA catabolites in urine can be used as a measure for the metabolism of each of the three major species of RNA. An accumulation of modified ribonucleosides appears in the serum of uremic patients. (PMID: 16527824, 16061253, 8043914, 2428556, 7159514, 9607216) [HMDB] N2-Methylguanine is a modified nucleoside.
