1-methyl-4-imidazoleacetate
Methylimidazoleacetic acid is the main metabolite of histamine. This end product of histamine catabolism is formed by N-methylation in the imidazole ring to methylhistamine by histamine methyltransferase (EC 2.1.1.8) and a subsequent oxidative deamination in the side chain by type B monoamine oxidase (EC 1.4.3.4). Based on studies, it is known that as much as 70 to 80 percent of the histamine metabolized in the body is excreted in the urine as methylimidazoleacetic acid. Thus, urinary methylimidazoleacetic acid being the major and specific histamine metabolite is a clear marker of any changes in histamine metabolism in the body. The urinary excretion of methylimidazoleacetic acid is considered a reliable indicator of histamine turnover rate in the body. The excretion of methylimidazoleacetic acid is higher in men than in women. However, this gender difference is abolished when corrected for creatinine excretion. A possible explanation is that basal histamine turnover is related to body size. There is no significant difference in methylimidazoleacetic acid excretion between smokers and non-smokers when analyzing absolute values (mg/24 h). When using methylimidazoleacetic acid values corrected for creatinine excretion female smokers have significantly higher methylimidazoleacetic acid excretion compared to nonsmokers (PMID:11411609, 7130180, 10350179, 10202992).

1,3-Dimethyluracil
1,3-Dimethyluracil is a methyl derivative of uric acid, found occasionally in human urine. 1,3-Dimethyluracil is one of the purine component in urinary calculi. Methylated purines originate from the metabolism of methylxanthines (caffeine, theophylline and theobromine). Methyluric acids are indistinguishable from uric acid by simple methods routinely used in clinical laboratories, requiring the use of high-performance liquid chromatography (HPLC). Purine derivatives in urinary calculi could be considered markers of abnormal purine metabolism. The content of a purine derivative in stone depends on its average urinary excretion in the general population, similarity to the chemical structure of uric acid, and content of the latter in stone. This suggests that purines in stones represent a solid solution with uric acid as solvent. It is also plausible that methylxanthines, ubiquitous components of the diet and drugs, are involved in the pathogenesis of urolithiasis.

3,5-Dihydroxyanisole
3,5-Dihydroxyanisole, also known as 5-methoxyresorcinol or flamenol, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 3,5-Dihydroxyanisole is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 3,5-dihydroxyanisole has been detected, but not quantified in, several different foods, such as annual wild rice, prairie turnips, thistles, grapefruit/pummelo hybrids, and pecan nuts. This could make 3,5-dihydroxyanisole a potential biomarker for the consumption of these foods. BioTransformer predicts that 3,5-dihydroxyanisole is a product of helichrysetin metabolism via a keto-hydrolysis-pattern5 reaction occurring in human gut microbiota and catalyzed by an unspecified-gutmicro enzyme (PMID: 30612223). 5-methoxybenzene-1,3-diol, also known as flamenol or 5-methoxyresorcinol, is a member of the class of compounds known as methoxyphenols.
