L-Histidine
Histidine (His), also known as L-histidine, is an alpha-amino acid. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 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. Histidine is one of 20 proteinogenic amino acids, i.e., the amino acids used in the biosynthesis of proteins. Histidine is found in all organisms ranging from bacteria to plants to animals. It is classified as an aliphatic, positively charged or basic amino acid. Histidine is a unique amino acid with an imidazole functional group. The acid-base properties of the imidazole side chain are relevant to the catalytic mechanism of many enzymes such as proteases. In catalytic triads, the basic nitrogen of histidine abstracts a proton from serine, threonine, or cysteine to activate it as a nucleophile. In a histidine proton shuttle, histidine is used to quickly shuttle protons. It can do this by abstracting a proton with its basic nitrogen to make a positively charged intermediate and then use another molecule to extract the proton from its acidic nitrogen. Histidine forms complexes with many metal ions. The imidazole sidechain of the histidine residue commonly serves as a ligand in metalloproteins. Histidine was first isolated by German physician Albrecht Kossel in 1896. Histidine is an essential amino acid in humans and other mammals. It was initially thought that it was only essential for infants, but longer-term studies established that it is also essential for adults. Infants four to six months old require 33 mg/kg of histidine. It is not clear how adults make small amounts of histidine, and dietary sources probably account for most of the histidine in the body. Histidine is a precursor for histamine and carnosine biosynthesis. Inborn errors of histidine metabolism, including histidinemia, maple syrup urine disease, propionic acidemia, and tyrosinemia I, exist and are marked by increased histidine levels in the blood. Elevated blood histidine is accompanied by a wide range of symptoms, from mental and physical retardation to poor intellectual functioning, emotional instability, tremor, ataxia and psychosis. Histidine and other imidazole compounds have anti-oxidant, anti-inflammatory and anti-secretory properties (PMID: 9605177 ). The efficacy of L-histidine in protecting inflamed tissue is attributed to the capacity of the imidazole ring to scavenge reactive oxygen species (ROS) generated by cells during acute inflammatory response (PMID: 9605177 ). Histidine, when administered in therapeutic quantities is able to inhibit cytokines and growth factors involved in cell and tissue damage (US patent 6150392). Histidine in medical therapies has its most promising trials in rheumatoid arthritis where up to 4.5 g daily have been used effectively in severely affected patients. Arthritis patients have been found to have low serum histidine levels, apparently because of very rapid removal of histidine from their blood (PMID: 1079527 ). Other patients besides arthritis patients that have been found to be low in serum histidine are those with chronic renal failure. Urinary levels of histidine are reduced in pediatric patients with pneumonia (PMID: 2084459 ). Asthma patients exhibit increased serum levels of histidine over normal controls (PMID: 23517038 ). Serum histidine levels are lower and are negatively associated with inflammation and oxidative stress in obese women (PMID: 23361591 ). Histidine supplementation has been shown to reduce insulin resistance, reduce BMI and fat mass and suppress inflammation and oxidative stress in obese women with metabolic syndrome. Histidine appears to suppress pro-inflammatory cytokine expression, possibly via the NF-κB pathway, in adipocytes (PMID: 23361591 ). Low plasma concentrations of histidine are associated with protein-energy...

Adenosine phosphosulfate
Adenosine phosphosulfate, also known as adenylylsulfate or adenosine sulfatophosphate, belongs to the class of organic compounds known as purine ribonucleoside monophosphates. These are nucleotides consisting of a purine base linked to a ribose to which one monophosphate group is attached. Adenosine phosphosulfate exists in all living species, ranging from bacteria to humans. Within humans, adenosine phosphosulfate participates in a number of enzymatic reactions. In particular, adenosine phosphosulfate can be biosynthesized from sulfate through the action of the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In addition, adenosine phosphosulfate can be converted into phosphoadenosine phosphosulfate; which is catalyzed by the enzyme bifunctional 3-phosphoadenosine 5-phosphosulfate synthase 2. In humans, adenosine phosphosulfate is involved in sulfate/sulfite metabolism. Outside of the human body, Adenosine phosphosulfate has been detected, but not quantified in several different foods, such as chia, yardlong beans, swiss chards, sapodilla, and chicory leaves. This could make adenosine phosphosulfate a potential biomarker for the consumption of these foods. An adenosine 5-phosphate having a sulfo group attached to one the phosphate OH groups. Adenosine phosphosulfate (also known as APS) is the initial compound formed by the action of ATP sulfurylase (or PAPS synthetase) on sulfate ions after sulfate uptake. PAPS synthetase 1 is a bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3-phosphoadenylylsulfate (PAPS). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate-activation pathway. [HMDB]. Adenosine phosphosulfate is found in many foods, some of which are muskmelon, garlic, caraway, and peach (variety).
Docetaxel
Docetaxel (sold under the brand name Taxotere) is a clinically well-established anti-mitotic chemotherapy medication (that is, it interferes with cell division). It is used mainly for the treatment of breast, ovarian, prostate, and non-small cell lung cancer. Docetaxel binds to microtubules reversibly with high affinity and has a maximum stoichiometry of 1 mole docetaxel per mole tubulin in microtubules. Docetaxel has been FDA-approved to treat patients who have locally advanced, or metastatic breast, or non-small-cell lung cancer who have undergone anthracycline-based chemotherapy and failed to stop cancer progression or relapsed. Docetaxel has a European approval for use in hormone-refractory prostate cancer. Docetaxel is a chemotherapeutic agent and is a cytotoxic compound. It is effectively a biologically damaging drug. As with all chemotherapy, adverse effects are common and many varying side-effects have been documented. Because docetaxel is a cell-cycle specific agent, it is cytotoxic to all dividing cells in the body. This includes tumour cells as well as hair follicles, bone marrow, and other germ cells. For this reason, common chemotherapy side effects such as alopecia occur (this can sometimes be permanent). The drug company Sanofi Aventis claims that they do not routinely keep this data. A survey being conducted in northwest France aims to establish exactly how many patients are being disfigured in this way. Independent studies show it could be as high as 6.3\\\% which puts this ASE in the common and frequent classification. Docetaxel is mainly metabolized in the liver by the cytochrome P450 CYP3A4 and CYP3A5 subfamilies of isoenzymes. Metabolism is principally oxidative and at the tert-butylpropionate side chain, resulting first in an alcohol docetaxel (M2), which is then cyclized to three further metabolites (M1, M3, and M4). M1 and M3 are two diastereomeric hydroxyoxazolidinones and M4 is an oxazolidinedione. Phase II trials of 577 patients showed that docetaxel clearance is related to body surface area and plasma levels of hepatic enzyme alpha-1-acid glycoprotein. Docetaxel is of the chemotherapy drug class taxane and is a semi-synthetic analogue of paclitaxel (Taxol), an extract from the bark of the rare Pacific yew tree Taxus brevifolia. Due to the scarcity of paclitaxel, extensive research was carried out which lead to the formulation of docetaxel, an esterified product of 10-deacetylbaccatin III. It was extracted from the renewable and readily available European yew tree. Drug interactions may be the result of altered pharmacokinetics or pharmacodynamics due to one of the drugs involved. Cisplatin, dexamethasone, doxorubicin, etoposide, and vinblastine are all potentially co-administered with docetaxel and did not modify docetaxel plasma binding in phase II studies. Cisplatin is known to have a complex interaction with some CYPs and has, in some events, been shown to reduce docetaxel clearance by up to 25\\\%. Anticonvulsants induce some metabolic pathways relevant to docetaxel. CYP450 and CYP3A show increased expression in response to the use of anticonvulsants and the metabolism of docetaxel metabolite M4 is processed by these CYPs. A corresponding increase in clearance of M4 by 25\\\% is observed in patients taking phenytoin and phenobarbital, common anticonvulsants. STAMPEDE is a UK-based six-arm, five-stage, open-label randomized controlled trial involving more than 3000 men. Arms C and E of this trial involve administering docetaxel to men starting long-term hormone therapy for the first time. This could be newly diagnosed metastatic, non-metastatic, or high-risk, previously-treated prostate cancer. The trial tests the value of the drug earlier in the treatment pathway instead of waiting until it has become androgen-independent. Docetaxel anhydrous is a tetracyclic diterpenoid that is paclitaxel with the N-benzyloxycarbonyl group replaced by N-tert-butoxycarbonyl, and the acetoxy group at position 10 replaced by a hydroxy group. It has a role as an antineoplastic agent, a photosensitizing agent and an antimalarial. It is a tetracyclic diterpenoid and a secondary alpha-hydroxy ketone. It derives from a hydride of a taxane. Docetaxel is a clinically well established anti-mitotic chemotherapy medication used mainly for the treatment of breast, ovarian, and non-small cell lung cancer. Docetaxel reversibly binds to tubulin with high affinity in a 1:1 stoichiometric ratio Docetaxel anhydrous is a Microtubule Inhibitor. The physiologic effect of docetaxel anhydrous is by means of Microtubule Inhibition. Docetaxel is an antineoplastic agent that has a unique mechanism of action as an inhibitor of cellular mitosis and that currently plays a central role in the therapy of many solid tumors including breast and lung cancer. Docetaxel therapy is frequently associated with serum enzyme elevations which are usually transient and mild, but more importantly has been linked to rapid onset, severe hypersensitivity reactions that can be associated with acute hepatic necrosis, liver failure and death. Docetaxel is a natural product found in Penicillium ubiquetum with data available. Docetaxel is a semi-synthetic, second-generation taxane derived from a compound found in the European yew tree, Taxus baccata. Docetaxel displays potent and broad antineoplastic properties; it binds to and stabilizes tubulin, thereby inhibiting microtubule disassembly which results in cell- cycle arrest at the G2/M phase and cell death. This agent also inhibits pro-angiogenic factors such as vascular endothelial growth factor (VEGF) and displays immunomodulatory and pro-inflammatory properties by inducing various mediators of the inflammatory response. Docetaxel has been studied for use as a radiation-sensitizing agent. (NCI04) Docetaxel Anhydrous is the anhydrous form of docetaxel, a semisynthetic side-chain analogue of paclitaxel with antineoplastic property. Docetaxel binds specifically to the beta-tubulin subunit of microtubules and thereby antagonizes the disassembly of the microtubule proteins. This results in the persistence of aberrant microtubule structures and results in cell-cycle arrest and subsequent cell death. Docetaxel is a clinically well established anti-mitotic chemotherapy medication used mainly for the treatment of breast, ovarian, and non-small cell lung cancer. Docetaxel binds to microtubules reversibly with high affinity and has a maximum stoichiometry of one mole docetaxel per mole tubulin in microtubules. A semisynthetic analog of PACLITAXEL used in the treatment of locally advanced or metastatic BREAST NEOPLASMS and NON-SMALL CELL LUNG CANCER.

Triphosphate
Triphosphate is a salt or ester containing three phosphate groups. It is the ionic form of triphosphoric acid, a condensed form of phosphoric acid. Triphosphate is an intermediate in the biosynthesis of folate, the metabolism of purine, the metabolism of porphyrin and chlorophyll, the metabolism of pyrimidine, and the metabolism of thiamine. It is a substrate for transforming protein p21/H-Ras-1, bis(5-adenosyl)-triphosphatase, ectonucleoside triphosphate diphosphohydrolase, DNA polymerase gamma subunit 1, DNA nucleotidylexotransferase, inosine triphosphate pyrophosphatase, cob(I)yrinic acid a,c-diamide adenosyltransferase (mitochondrial), thiamine-triphosphatase, DNA-directed RNA polymerase III 32 kDa polypeptide, and 6-pyruvoyl tetrahydrobiopterin synthase. Compounds such as ATP (adenosine triphosphate) are esters of triphosphoric acid. Polyphosphates are hydrolyzed into smaller units (orthophosphates) in the gut before absorption, which may induce metabolic acidosis. The acute toxicity of polyphosphonates is low as the lowest LD50 after oral administration is > 1,000 mg/kg body weight. Polyphosphates are moderately irritating to skin and mucous membrane because of their alkalinity. No mutagenic potential was observed when TTP was tested in a Salmonella/microsome assay (Ames test) and in a chromosomal aberration assay in vitro using a Chinese hamster fibroblast cell line (Ishidate et al. 1984). Tetrasodium pyrophosphate was not mutagenic in an in vitro assay using S. cerevisiae strains and S. typhimurium strains with and without the addition of mammalian metabolic activation preparations (IPCS 1982). Reproduction studies in three generations of rats on diets with 0.5\\% TTP were performed. TTP had no effects on fertility or litter size, or on growth or survival on offspring (Hodge 1964). Triphosphoric acid, also tripolyphosphoric acid, with formula H5P3O10, is a condensed form of phosphoric acid. In polyphosphoric acids, it is the next after pyrophosphoric acid, H4P2O7, also called diphosphoric acid. Compounds such as ATP (adenosine triphosphate) are esters of triphosphoric acid. [Wikipedia]
Diadenosine tetraphosphate
Diadenosine tetraphosphate (AP4A) is a diadenosine polyphosphate. Diadenosine polyphosphates (APnAs, n=3-6) are a family of endogenous vasoactive purine dinucleotides which have been isolated from thrombocytes. APnAs have been demonstrated to be involved in the control of vascular tone as well as the growth of vascular smooth muscle cells and hence, possibly, in atherogenesis. APnAs isolated substances are Ap3A, Ap4A, Ap5A, and Ap6A. APnAs are naturally occurring substances that facilitate tear secretion; they are released from the corneal epithelium, they stimulate tear production and therefore they may be considered as physiological modulators of tear secretion. The APnAs were discovered in the mid-sixties in the course of studies on aminoacyl-tRNA synthetases (aaRS). APnAs have emerged as intracellular and extracellular signalling molecules implicated in the maintenance and regulation of vital cellular functions and become considered as second messengers. Great variety of physiological and pathological effects in mammalian cells was found to be associated with alterations of APnAs. APnAs are polyphosphated nucleotidic substances which are found in the CNS and are known to be released in a calcium-dependent manner from storage vesicles in brain synaptosomes. AP5A is a specific adenylate kinase inhibitor in the hippocampus, decreasing the rate of decomposition of ADP and the formation of ATP; a pathway that influences the availability of purines in the central nervous system. AP4A is the only APnA that can induce a considerable increase in [Ca2+] in endothelial cells, indicating that its vasoactive effects are comparable to the known effects of arginine vasopressin, Angiotensin II, and ATP. AP4A is a ubiquitous ApnA is a signal molecule for DNA replication in mammalian cells. AP4A is a primer for oligoadenylate synthesis catalyzed by interferon-inducible 2-5A synthetase. AP4A is an avid inhibitor of eosinophil-derived neurotoxin (EDN). EDN is a catalytically proficient member of the pancreatic ribonuclease superfamily secreted along with other eosinophil granule proteins during innate host defense responses and various eosinophil-related inflammatory and allergic diseases. The ribonucleolytic activity of EDN is central to its antiviral and neurotoxic activities and possibly to other facets of its biological activity.

Methyleugenol
Methyleugenol, also known as 4-allylveratrole or eugenol methyl, belongs to the class of organic compounds known as dimethoxybenzenes. These are organic aromatic compounds containing a monocyclic benzene moiety carrying exactly two methoxy groups. FDA noted the action was despite its continuing stance that this substance does not pose a risk to public health under the conditions of its intended use. Methyleugenol is a sweet, anise, and apricot tasting compound. Methyleugenol is found, on average, in the highest concentration within a few different foods, such as allspices, tarragons, and sweet bay and in a lower concentration in sweet basils, rosemaries, and hyssops. Methyleugenol has also been detected, but not quantified, in several different foods, such as soy beans, evergreen blackberries, muskmelons, citrus, and pomes. This could make methyleugenol a potential biomarker for the consumption of these foods. As of October 2018, the US FDA withdrew authorization for the use of methyl eugenol as a synthetic flavoring substance for use in food because petitioners provided data demonstrating that these additives induce cancer in laboratory animals. Methyleugenol is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Methyl eugenol (allylveratrol) is a natural chemical compound classified as a phenylpropene, a type of phenylpropanoid. It is the methyl ether of eugenol and is important to insect behavior and pollination. Their ability to attract insects, particularly Bactrocera fruit flies was first noticed in 1915 by F. M. Howlett. The compound may have evolved in response to pathogens, as methyl eugenol has some antifungal activity. Methyl eugenol is found in a number of plants (over 450 species from 80 families including both angiosperm and gymnosperm families) and has a role in attracting pollinators. About 350 plant species have them as a component of floral fragrance. Methyleugenol is a clear colorless to pale yellow liquid with a spicy earthy odor. Bitter burning taste. (NTP, 1992) O-methyleugenol is a phenylpropanoid. It is functionally related to a eugenol. Methyleugenol is a natural product found in Vitis rotundifolia, Elettaria cardamomum, and other organisms with data available. Methyleugenol is a yellowish, oily, naturally occurring liquid with a clove-like aroma and is present in many essential oils. Methyleugenol is used as a flavoring agent, as a fragrance and as an anesthetic in rodents. Methyleugenol is mutagenic in animals and is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in animals. (NCI05) Methyleugenol is found in allspice. Methyleugenol is present in many essential oils, e.g. nutmeg, mace and also many fruits, e.g. apple, banana, orange juice or peel, grapefruit, bilberryMethyleugenol has been shown to exhibit anti-nociceptive function (A7914).Methyleugenol belongs to the family of Anisoles. These are organic compounds contaiing a methoxybenzene or a derivative thereof. Present in many essential oils, e.g. nutmeg, mace and also many fruits, e.g. apple, banana, orange juice or peel, grapefruit, bilberry. Methyleugenol is found in many foods, some of which are wild carrot, sweet basil, citrus, and fruits.

4-Nitrotoluene
P-nitrotoluene appears as a yellow liquid with a weak aromatic odor. Toxic. Insoluble in water. Combustible but may take some effort to ignite. Produces toxic oxides of nitrogen when burned. In a spill, immediate steps should be taken to limit its spread to the environment. Can easily penetrate the soil and contaminate groundwater or nearby streams. Used to make other chemicals. 4-Nitrotoluene is an organic compound with the chemical formula C7H7NO2. It is a yellowish liquid or solid, depending on the temperature, and has a characteristic aromatic odor. This compound is primarily used in industrial applications, such as in the production of dyes, pesticides, and other chemicals. In terms of its toxicity to humans: Acute Toxicity: 4-Nitrotoluene can enter the body through inhalation, skin contact, and ingestion. Acute exposure can lead to irritation of the eyes and skin, headaches, dizziness, nausea, vomiting, and liver damage. Chronic Toxicity: Prolonged exposure to 4-nitrotoluene can result in more severe health issues, including damage to the liver and kidneys, effects on the central nervous system, and a potential risk of cancer. Environmental and Health Impact: 4-Nitrotoluene can be found in water and soil, posing a risk to aquatic life. It can also accumulate in the food chain. Due to its toxicity and potential health risks, 4-nitrotoluene is typically subject to strict control and regulation, especially in industrial settings. Appropriate safety measures, such as wearing personal protective equipment and following safe operating procedures, are necessary when handling this chemical.
Oxazepam
Oxazepam is only found in individuals that have used or taken this drug. It is an intermediate-acting benzodiazepine used to treat alcohol withdrawal and anxiety disorders. It is a metabolite of diazepam, prazepam, temazepam, and clorazepate, and has moderate amnesic, anxiolytic, anticonvulsant, hypnotic, sedative, and skeletal muscle relaxant properties compared to other benzodiazepines (Wikipedia). Like other benzodiazepines, oxazepam exerts its anxiolytic effects by potentiating the effect of gamma-aminobutyric acid (GABA) on GABA-A receptors through a cooperative mechanism of action. GABA receptors are ionotropic chloride-linked channel receptors that produce inhibitory postsynaptic potentials. When activated by GABA, the GABA receptor/chloride ionophore complex undergoes a conformational change that allows the passage of chloride ions through the channel. Benzodiazepines are believed to exert their effect by increasing the effect of GABA at its receptor. Benzodiazepine binding increases chloride conductance in the presence of GABA by increasing the frequency at which the channel opens. In contrast, barbiturates increase chloride conductance in the presence of GABA by prolonging the time in which the channel remains open. There are 18 subtypes of the GABA receptor subunits. The α2 subunit of the α2β3γ2 receptor complex is thought to mediate anxiolytic effects while the α1 subunit of the α1β2γ2 receptor complex is thought to mediate sedative, anticonvulsant, and anterograde amnesia effects.

1-Methyl-4-nitrobenzene
4-Nitrotoluene, being a volatile organic compound, can potentially penetrate the skin epidermis under certain conditions. The skin is a complex barrier that can prevent many substances from entering the body, but it is not impervious to all chemicals, especially those that are small, lipophilic (fat-soluble), and volatile. The epidermis, the outermost layer of the skin, consists of several sub-layers, including the stratum corneum, which is the primary barrier to external agents. Substances can pass through the skin via two main routes: transcellular (through the cells) and intercellular (between the cells). The efficiency of this penetration depends on various factors, such as the concentration of the compound, the duration of exposure, the condition of the skin (e.g., damaged or intact), and the chemical's properties. In the case of 4-nitrotoluene, if there is direct contact with the skin, especially in liquid or high vapor concentration forms, it could potentially penetration through the skin layers. This is particularly a concern in occupational settings where workers might be exposed to this compound without adequate protection. To minimize the risk of skin absorption, it is crucial to use appropriate personal protective equipment, such as gloves and aprons, when handling 4-nitrotoluene or any other potentially hazardous chemicals. In case of skin contact, it is important to wash the affected area immediately with soap and water and seek medical attention if necessary.
