L-Histidinol
L-Histidinol, a structural analogue of the essential amino acid L-histidine, enhances the toxicity of a variety of anticancer drugs for many tumour cells of animal origin (PMID:8297120). L-Histidinol inhibits human myristoyl-CoA:protein-myristoyltransferase (hNMT), an essential eukaryotic enzyme that catalyzes the cotranslational transfer of myristate into the NH2-terminal glycine residue of a number of important proteins of diverse function (PMID:9778369). L-Histidinol, a structural analogue of the essential amino acid L-histidine, enhances the toxicity of a variety of anticancer drugs for many tumor cells of animal origin. (PMID 8297120)
3-Methyladenine
3-Methyladenine, also known as 3-ma nucleobase, belongs to the class of organic compounds known as 6-aminopurines. These are purines that carry an amino group at position 6. Purine is a bicyclic aromatic compound made up of a pyrimidine ring fused to an imidazole ring. 3-Methyladenine exists in all living species, ranging from bacteria to humans. 3-Methyladenine has been detected, but not quantified, in several different foods, such as soft-necked garlics, chinese bayberries, burbots, amaranths, and tea. This could make 3-methyladenine a potential biomarker for the consumption of these foods. 3-Methyladenine is one of the purines damaged by alkylation and oxidation which can be recognized and excised by the human 3-methyladenine DNA glycosylase (AAG) (EC: EC3.2.2.21). 3-Methyladenine is one of the purines damaged by alkylation and oxidation which can be recognized and excised by the human 3-methyladenine DNA glycosylase (AAG) (EC: EC 3.2.2.21) [HMDB]. 3-Methyladenine is found in many foods, some of which are sacred lotus, evergreen huckleberry, swamp cabbage, and red rice.

Pilocarpine
Pilocarpine is only found in individuals that have used or taken this drug. It is a slowly hydrolyzed muscarinic agonist with no nicotinic effects. Pilocarpine is used as a miotic and in the treatment of glaucoma. [PubChem]Pilocarpine is a cholinergic parasympathomimetic agent. It increase secretion by the exocrine glands, and produces contraction of the iris sphincter muscle and ciliary muscle (when given topically to the eyes) by mainly stimulating muscarinic receptors.

1-Methylhistamine
1-Methylhistamine, also known as H137, belongs to the class of organic compounds known as 2-arylethylamines. These are primary amines that have the general formula RCCNH2, where R is an organic group. 1-Methylhistamine exists in all living organisms, ranging from bacteria to humans. Within humans, 1-methylhistamine participates in a number of enzymatic reactions. In particular, S-adenosylhomocysteine and 1-methylhistamine can be biosynthesized from S-adenosylmethionine and histamine; which is mediated by the enzyme histamine N-methyltransferase. In addition, 1-methylhistamine can be converted into methylimidazole acetaldehyde through its interaction with the enzyme amine oxidase [flavin-containing] a. In humans, 1-methylhistamine is involved in histidine metabolism. 1-Methylhistamine is a potentially toxic compound. 1-Methylhistamine is a histamine metabolite. It is a product of histamine 1-methyltransferase [EC 2.1.1.8] in the pathway histidine metabolism (KEGG). [HMDB] Acquisition and generation of the data is financially supported in part by CREST/JST.

Cucumopine
Cucumopine, also known as mikimopine or cucumopine, (4r-cis)-isomer, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. Cucumopine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Cucumopine can be found in carrot and wild carrot, which makes cucumopine a potential biomarker for the consumption of these food products.
