C15H14O3 (242.0943)


Beta-lapachone is a benzochromenone that is 3,4-dihydro-2H-benzo[h]chromene-5,6-dione substituted by geminal methyl groups at position 2. Isolated from Tabebuia avellanedae, it exhibits antineoplastic and anti-inflammatory activities. It has a role as an antineoplastic agent, an anti-inflammatory agent and a plant metabolite. It is a benzochromenone and a member of orthoquinones. Lapachone has been used in trials studying the treatment of Cancer, Carcinoma, Advanced Solid Tumors, Head and Neck Neoplasms, and Carcinoma, Squamous Cell. beta-Lapachone is a natural product found in Markhamia stipulata, Markhamia lutea, and other organisms with data available. Lapachone is a poorly soluble, ortho-naphthoquinone with potential antineoplastic and radiosensitizing activity. Beta-lapachone (b-lap) is bioactivated by NAD(P)H:quinone oxidoreductase-1 (NQO1), creating a futile oxidoreduction that generates high levels of superoxide. In turn, the highly reactive oxygen species (ROS) interact with DNA, thereby causing single-strand DNA breaks and calcium release from endoplasmic reticulum (ER) stores. Eventually, the extensive DNA damage causes hyperactivation of poly(ADP-ribose) polymerase-1 (PARP-1), an enzyme facilitating DNA repair, accompanied by rapid depletion of NAD+/ATP nucleotide levels. As a result, a caspase-independent and ER-stress induced mu-calpain-mediated cell death occurs in NQO1-overexpressing tumor cells. NQO1, a flavoprotein and two-electron oxidoreductase, is overexpressed in a variety of tumors.

1-Methylhistidine

(2S)-2-Amino-3-(1-methyl-1H-imidazol-4-yl)propanoic acid

C7H11N3O2 (169.0851)


1-Methylhistidine, also known as 1-MHis or 1MH, belongs to the class of organic compounds known as histidine and derivatives. 1MH is also classified as a methylamino acid. Methylamino acids are primarily proteogenic amino acids (found in proteins) which have been methylated (in situ) on their side chains by various methyltransferase enzymes. Histidine can be methylated at either the N1 or N3 position of its imidazole ring, yielding the isomers 1-methylhistidine (1MH; also referred to as pi-methylhistidine) or 3-methylhistidine (3MH; tau-methylhistidine), respectively. There is considerable confusion with regard to the nomenclature of the methylated nitrogen atoms on the imidazole ring of histidine and other histidine-containing peptides such as anserine. In particular, older literature (mostly prior to the year 2000) designated anserine (Npi methylated) as beta-alanyl-N1-methyl-histidine, whereas according to standard IUPAC nomenclature, anserine is correctly named as beta-alanyl-N3-methyl-histidine. As a result, many papers published prior to the year 2000 incorrectly identified 1MH as a specific marker for dietary consumption or various pathophysiological effects when they really were referring to 3MH (PMID: 24137022). Recent discoveries have shown that 1MH is produced in essentially all mammals (and other vertebrates) via the enzyme known as METTL9 (PMID: 33563959). METTL9 is a broad-specificity methyltransferase that mediates the formation of the majority of 1MH present in mammalian proteomes. METTL9-catalyzed methylation requires a His-x-His (HxH) motif, where "x" is a small amino acid. This HxH motif is found in a number of abundant mammalian proteins such as ARMC6, S100A9, and NDUFB3 (PMID: 33563959). Because of its abundance in many muscle-related proteins, 1MH has been found to be a good biomarker for the consumption of meat (PMID: 21527577). Dietary studies have shown that poultry consumption (p-trend = 0.0006) and chicken consumption (p-trend = 0.0003) are associated with increased levels of 1MH in human plasma (PMID: 30018457). The consumption of fish, especially salmon and cod, has also been shown to increase the levels of 1MH in serum and urine (PMID: 31401679). As a general rule, urinary 1MH is associated with white meat intake (p< 0.001), whereas urinary 3MH is associated with red meat intake (p< 0.001) (PMID: 34091671). 1-Methyl-L-histidine is an objective indicator of meat ingestion and exogenous 3-methylhistidine (3MH) intake. 1-Methyl-L-histidine is an objective indicator of meat ingestion and exogenous 3-methylhistidine (3MH) intake. 3-Methyl-L-histidine is a biomarker for meat consumption, especially chicken. It is also a biomarker for the consumption of soy products.

   

N-Acetylleucine

(2S)-2-acetamido-4-methylpentanoic acid

C8H15NO3 (173.1052)


N-Acetyl-L-leucine or N-Acetylleucine, belongs to the class of organic compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. N-Acetylleucine can also be classified as an alpha amino acid or a derivatized alpha amino acid. Technically, N-Acetylleucine is a biologically available N-terminal capped form of the proteinogenic alpha amino acid L-lecuine. N-acetyl amino acids can be produced either via direct synthesis of specific N-acetyltransferases or via the proteolytic degradation of N-acetylated proteins by specific hydrolases. N-terminal acetylation of proteins is a widespread and highly conserved process in eukaryotes that is involved in protection and stability of proteins (PMID: 16465618). About 85\\\\% of all human proteins and 68\\\\% of all yeast proteins are acetylated at their N-terminus (PMID: 21750686). Several proteins from prokaryotes and archaea are also modified by N-terminal acetylation. The majority of eukaryotic N-terminal-acetylation reactions occur through N-acetyltransferase enzymes or NAT’s (PMID: 30054468). These enzymes consist of three main oligomeric complexes NatA, NatB, and NatC, which are composed of at least a unique catalytic subunit and one unique ribosomal anchor. The substrate specificities of different NAT enzymes are mainly determined by the identities of the first two N-terminal residues of the target protein. The human NatA complex co-translationally acetylates N-termini that bear a small amino acid (A, S, T, C, and occasionally V and G) (PMID: 30054468). NatA also exists in a monomeric state and can post-translationally acetylate acidic N-termini residues (D-, E-). NatB and NatC acetylate N-terminal methionine with further specificity determined by the identity of the second amino acid. N-acetylated amino acids, such as N-acetylleucine can be released by an N-acylpeptide hydrolase from peptides generated by proteolytic degradation (PMID: 16465618). In addition to the NAT enzymes and protein-based acetylation, N-acetylation of free leucine can also occur. In particular, N-Acetylleucine can be biosynthesized from L-leucine and acetyl-CoA by the enzyme leucine N-acetyltransferase (EC 2.3.1.66). Excessive amounts N-acetyl amino acids including N-acetylleucine (as well as N-acetylglycine, N-acetylserine, N-acetylglutamine, N-acetylglutamate, N-acetylalanine, N-acetylmethionine and smaller amounts of N-acetylthreonine, N-acetylisoleucine, and N-acetylvaline) can be detected in the urine with individuals with acylase I deficiency, a genetic disorder (PMID: 16465618). Aminoacylase I is a soluble homodimeric zinc binding enzyme that catalyzes the formation of free aliphatic amino acids from N-acetylated precursors. In humans, Aminoacylase I is encoded by the aminoacylase 1 gene (ACY1) on chromosome 3p21 that consists of 15 exons (OMIM 609924). Individuals with aminoacylase I deficiency will experience convulsions, hearing loss and difficulty feeding (PMID: 16465618). ACY1 can also catalyze the reverse reaction, the synthesis of acetylated amino acids. Many N-acetylamino acids, including N-acetylleucine are classified as uremic toxins if present in high abundance in the serum or plasma (PMID: 26317986; PMID: 20613759). Uremic toxins are a diverse group of endogenously produced molecules that, if not properly cleared or eliminated by the kidneys, can cause kidney damage, cardiovascular disease and neurological deficits (PMID: 18287557).

Urocanic acid

(2E)-3-(1H-Imidazol-5-yl)-2-propenoic acid

C6H6N2O2 (138.0429)


Urocanic acid (CAS: 104-98-3) is a breakdown (deamination) product of histidine. In the liver, urocanic acid is an intermediate in the conversion of histidine to glutamic acid, whereas, in the epidermis, it accumulates and may be both a UV protectant and an immunoregulator. Urocanic acid (UA) exists as a trans isomer (t-UA, approximately 30 mg/cm2) in the uppermost layer of the skin (stratum corneum). t-UA is formed as the cells of the second layer of the skin become metabolically inactive. During this process, proteins and membranes degrade, histidine is released, and histidase (histidine ammonia lyase) catalyzes the deamination of histidine to form t-UA. t-UA accumulates in the epidermis until removal by either the monthly skin renewal cycle or sweat. Upon absorption of UV light, the naturally occurring t-UA isomerizes to its cis form, c-UA. Because DNA lesions (e.g., pyrimidine dimers) in the lower epidermis can result from UV-B absorption, initial research proposed that t-UA acted as a natural sunscreen absorbing UV-B in the stratum corneum before the damaging rays could penetrate into lower epidermal zones. Researchers have found that c-UA also suppresses contact hypersensitivity and delayed hypersensitivity, reduces the Langerhans cell count in the epidermis, prolongs skin-graft survival time, and affects natural killer cell activity. (E)-Urocanic acid is found in mushrooms. It has been isolated from Coprinus atramentarius (common ink cap) and Phallus impudicus (common stinkhorn). Trans-urocanic acid, also known as 4-imidazoleacrylic acid or urocanate, belongs to imidazolyl carboxylic acids and derivatives class of compounds. Those are organic compounds containing a carboxylic acid chain (of at least 2 carbon atoms) linked to an imidazole ring. Trans-urocanic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Trans-urocanic acid can be found in mung bean, which makes trans-urocanic acid a potential biomarker for the consumption of this food product. Trans-urocanic acid can be found primarily in most biofluids, including sweat, feces, blood, and urine, as well as in human liver and skin tissues. Trans-urocanic acid exists in all living organisms, ranging from bacteria to humans. In humans, trans-urocanic acid is involved in the histidine metabolism. Trans-urocanic acid is also involved in a couple of metabolic disorders, which include ammonia recycling and histidinemia.

Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway. Levuglandins (LGs) and their stereo and structural isomers are extraordinarily reactive γ-ketoaldehydes that are generated by rearrangements of prostanoid endoperoxide intermediates of polyene cyclooxygenation. Their rapid adduction with biological nucleophiles results, inter alia, in pathological modifications of proteins and DNA. It also complicates their detection. Cyclooxygenase-promoted lipid oxidation is a pivotal step in the biosynthesis of an array of physiologically active metabolites. COX fosters a highly regio and stereoselective cyclooxygenation of arachidonic acid (AA) to deliver a single, enantiomerically pure endoperoxide, PGH2, that is a branch point in the biosynthesis of numerous hormone-like mediators of cellular activities. Spontaneous rearrangements of PGH2 were known to generate prostaglandins (PG) PGD2 and PGE2. (PMID: 15752459) [HMDB] Levuglandin E2 is a levuglandin generated in the cyclooxygenase (COX) pathway.

3-Methylhistidine

(2S)-2-Amino-3-(1-methyl-1H-imidazol-5-yl)propanoic acid

C7H11N3O2 (169.0851)


3-Methylhistidine, also known as 3-MHis or 3MH, belongs to the class of organic compounds known as histidine and derivatives. 3MH is also classified as a methylamino acid. Methylamino acids are primarily proteogenic amino acids (found in proteins) which have been methylated (in situ) on their side chains by various methyltransferase enzymes. 3-Methylhistidine is also classified as 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. Amino acids are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain (R group) specific to each amino acid. 3-Methylhistidine is generated from histidine residues found in proteins. Histidine can be methylated at either the N1 or N3 position of its imidazole ring, yielding the isomers 1-methylhistidine (1MH; also referred to as pi-methylhistidine) or 3-methylhistidine (3MH; tau-methylhistidine), respectively. There is considerable confusion with regard to the nomenclature of the methylated nitrogen atoms on the imidazole ring of histidine and other histidine-containing peptides such as anserine. In particular, older literature (mostly prior to the year 2000) designated anserine (Npi methylated) as beta-alanyl-N1-methyl-histidine, whereas according to standard IUPAC nomenclature, anserine is correctly named as beta-alanyl-N3-methyl-histidine. As a result, many papers published prior to the year 2000 incorrectly identified 1MH as a specific marker for dietary consumption or various pathophysiological effects when they really were referring to 3MH (PMID: 24137022). Histidine methylation on the 3- or tau site is mediated by the enzyme known as METTL18. METTL18 is a nuclear methyltransferase protein that contains a functional nuclear localization signal and accumulates in nucleoli. Urinary concentrations of 3-methylhistidine can be used as a biomarker for skeletal muscle protein breakdown in humans who have been subject to muscle injury (PMID: 16079625). 3-methylhistidine is formed by the posttranslational methylation of histidine residues of the main myofibrillar proteins actin and myosin. During protein catabolism, 3-methylhistidine is released but cannot be reutilized. Therefore, the plasma concentration and urine excretion of 3-methylhistidine are sensitive markers of myofibrillar protein degradation (PMID: 32235743). Approximately 75\\\% of 3-methylhistidine is estimated to originate from skeletal muscle (PMID: 32235743). In addition to the degradation of muscle proteins, the 3-methylhistidine level is affected by the degradation of intestinal proteins and meat intake. 3-Methylhistidine exists in all eukaryotes, ranging from yeast to humans. In humans, 3-methylhistidine is involved in methylhistidine metabolism. 3-Methylhistidine has been found to be associated with several diseases such as diabetes mellitus type 2, eosinophilic esophagitis, and kidney disease. The normal concentration of 3-methylhistidine in the urine of healthy adult humans has been detected and quantified in a range of 3.63–69.27 micromoles per millimole (umol/mmol) of creatinine, with most studies reporting the average urinary concentration between 15–20 umol/mmol of creatinine. The average concentration of 3-methylhistidine in human blood plasma has been detected and quantified at 2.85 micromolar (uM) with a range of 0.0–5.9 uM. As a general rule, urinary 1MH is associated with white meat intake (p< 0.001), whereas urinary 3MH is associated with red meat intake (p< 0.001) (PMID: 34091671). 3-Methyl-L-histidine is a biomarker for meat consumption, especially chicken. It is also a biomarker for the consumption of soy products.

C6H6N2O2 (138.0429)


An alpha,beta-unsaturated monocarboxylic acid that is prop-2-enoic acid substituted by a 1H-imidazol-4-yl group at position 3. It is a metabolite of hidtidine. Urocanic acid is an intermediate in the catabolism of L-histidine.; Urocanic is a breakdown (deamination) product of histidine. In the liver, urocanic acid is an intermediate in the conversion of histidine to glutamic acid, whereas in the epidermis, it accumulates and may be both a UV protectant and an immunoregulator. Urocanic acid (UA) exists as a trans isomer (t-UA, approximately 30 mg/cm2) in the uppermost layer of the skin (stratum corneum). t-UA is formed as the cells of the second layer of skin become metabolically inactive. During this process, proteins and membranes degrade, histidine is released, and histidase (histidine ammonia lyase) catalyzes the deamination of histidine to form t-UA. t-UA accumulates in the epidermis until removal by either the monthly skin renewal cycle or sweat. Upon absorption of UV light, the naturally occurring t-UA isomerizes to its cis form, c-UA. Because DNA lesions (e.g., pyrimidine dimers) in the lower epidermis can result from UV-B absorption, initial research proposed that t-UA acted as a natural sunscreen absorbing UV-B in the stratum corneum before the damaging rays could penetrate into lower epidermal zones. Researchers have found that c-UA also suppresses contact hypersensitivity and delayed hypersensitivity, reduces the Langerhans cell count in the epidermis, prolongs skin-graft survival time, and affects natural killer cell activity. Urocanic acid is found in mung bean.

Byakangelicin is an aldose-reductase inhibitor with an IC50 value of 6.2 μM[1]. Byakangelicin, one of the active compounds found in the roots of Angelica gigas, can serve as a modulator to improve brain accumulation of diverse active compounds (Umb, Cur, and Dox) and enhance therapeutic effects[1]. Byakangelicin is likely to increase the expression of all PXR target genes (such as MDR1) and induce a wide range of agent-agent interactions. Byakangelicin can inhibit the effects of sex hormones, it may increase the catabolism of endogenous hormones[2].
