Natural Product Identification
Common Name1-Methylguanine
Description1-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 ).
