Etomidate

(R)-(+)-1-(alpha-Methylbenzyl)imidazole-5-carboxylic acid ethyl ester

C14H16N2O2 (244.1212)


Etomidate is only found in individuals that have used or taken this drug. It is an midazole derivative anesthetic and hypnotic with little effect on blood gases, ventilation, or the cardiovascular system. It has been proposed as an induction anesthetic. [PubChem]Etomidate binds at a distinct binding site associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.

Pyroglutamic acid

(S)-(-)-gamma-Butyrolactam-gamma-carboxylic acid

C5H7NO3 (129.0426)


Pyroglutamic acid (5-oxoproline) is a cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam. It is formed nonenzymatically from glutamate, glutamine, and gamma-glutamylated peptides, but it can also be produced by the action of gamma-glutamylcyclotransferase on an L-amino acid. Elevated blood levels may be associated with problems of glutamine or glutathione metabolism. This compound is found in substantial amounts in brain tissue and other tissues in bound form, especially skin. It is also present in plant tissues. It is sold, over the counter, as a "smart drug" for improving blood circulation in the brain. Pyroglutamate in the urine is a biomarker for the consumption of cheese. When present in sufficiently high levels, pyroglutamic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of pyroglutamic acid are associated with at least five inborn errors of metabolism including 5-oxoprolinuria, 5-oxoprolinase deficiency, glutathione synthetase deficiency, hawkinsinuria, and propionic acidemia. Pyroglutamic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. It has been shown that pyroglutamic acid releases GABA from the cerebral cortex and displays anti-anxiety effects in a simple approach-avoidance conflict situation in the rat. In clinical pharmacology experiments, pyroglutamic acid significantly shortens the plasma half-life of ethanol during acute intoxication. Found in vegetables, fruits and molasses. A cyclized derivative of L-glutamic acid. It is an uncommon amino acid derivative in which the free amino group of glutamic acid cyclizes to form a lactam.

Carbimazole

ethyl 3-methyl-2-sulfanylidene-2,3-dihydro-1H-imidazole-1-carboxylate

C7H10N2O2S (186.0463)


Carbimazole is only found in individuals that have used or taken this drug. It is an imidazole antithyroid agent. Carbimazole is metabolized to methimazole, which is responsible for the antithyroid activity. [PubChem]Carbimazole is an aitithyroid agent that decreases the uptake and concentration of inorganic iodine by thyroid, it also reduces the formation of di-iodotyrosine and thyroxine. Once converted to its active form of methimazole, it prevents the thyroid peroxidase enzyme from coupling and iodinating the tyrosine residues on thyroglobulin, hence reducing the production of the thyroid hormones T3 and T4.

Safrole

4-Allyl-1,2-(methylenedioxy)benzene, 8ci

C10H10O2 (162.0681)


Safrole, also known as shikimol, is a colorless or slightly yellow oily liquid. It is typically extracted from the root-bark or the fruit of sassafras plants in the form of sassafras oil, or synthesized from other related methylenedioxy compounds. It is the principal component of brown camphor oil, and is found in small amounts in a wide variety of plants, where it functions as a natural pesticide. Safrole is found in anise and nutmeg. Banned by FDA for use in food. Safrole is formerly used as a food flavour It is a precursor in the synthesis of the insecticide synergist piperonyl butoxide and the recreational drug MDMA ("Ecstacy"). Safrole is a natural plant constituent, found in oil of sassafras and certain other essential oils. It is a member of the methylenedioxybenzene group of compounds, many of which (e.g. piperonyl butoxide) are extensively used as insecticide synergists. Safrole is a major source of human exposure to safrole is through consumption of spices, such as nutmeg, cinnamon and black pepper, in which safrole is a constituent. Safrole is also present in root beer, and has been used as an additive in chewing gum, toothpaste, soaps and certain pharmaceutical preparations. Safrole is a weak hepatocarcinogen and it is a matter of considerable interest whether the ally1 moiety or the methylenedioxy group, or both, are involved in the mechanism of its carcinogenesis. Safrole is extensively metabolized, giving rise to a large number of metabolites. Metabolism involves essentially two major routes, oxidation of the ally1 side chain, and oxidation of the methylenedioxy group with subsequent cleavage to form the catechol. Safrole undergoes oxidation of the allylic group to yield the 2, 3-epoxide (safrole epoxide). The dihydrodiol is one of the metabolites of safrole, and presumably arises from the hydration of the 2, 3-epoxide. The principal route of metabolism of safrole is through cleavage of the methylenedioxy group, the major metabolites being allylcatechol and its isomer, propenylcatechol. Eugenol and its isomer I-methoxy- 2-hydroxy-4-allylbenzene have been detected as minor metabolites in rat, mouse and human (PMID:6719936). The Ocotea cymbarum oil made of the Ocotea pretiosa, a plant growing in Brazil, and sassafras oil made of Sassafras albidum, a tree growing in eastern North America, are the main natural sources for safrole. It has a characteristic "candy-shop" aroma Occurs in nutmeg. Banned by FDA for use in food. Formerly used as a food flavour

Imidazole

N,N-1,2-ethenediylmethanimidamide

C3H4N2 (68.0374)


Imidazole is an organic compound with the formula C3N2H4. It is a white or colourless solid that is soluble in water, producing a mildly alkaline solution. In chemistry, it is an aromatic heterocycle, classified as a diazole, and has non-adjacent nitrogen atoms. Imidazole is a heterocyclic aromatic organic compound. It is classified as an alkaloid. The ring system of the molecule is present in important biological building blocks such as histidine and histamine. Imidazole can act as a base and as a weak acid. Imidazole exists in two tautomeric forms with the hydrogen atom moving between the two nitrogens. Many drugs contain an imidazole ring, such as antifungal drugs and nitroimidazole. Imidazole is a 5 membered planar ring which is soluble in water and polar solvents. Imidazole is a base and an excellent nucleophile. It reacts at the NH nitrogen, attacking alkylating and acylating compounds. It is not particularly susceptible to electrophilic attacks at the carbon atoms, and most of these reactions are substitutions that keep the aromaticity intact. One can see from the resonance structure that the carbon-2 is the carbon most likely to have a nucleophile attack it, but in general nucleophilic substitutions are difficult with imidazole. Imidazole is incorporated into many important biological molecules. The most obvious is the amino acid histidine, which has an imidazole side chain. histidine is present in many proteins and enzymes and plays a vital part in the structure and binding functions of hemoglobin. Isolated from the seeds of Lens culinaris (lentil)and is also present in the seeds of other legumes: Macrotyloma uniflorum (horse gram), Psophocarpus tetragonolobus (winged bean), Vigna radiata (mung bean) CONFIDENCE standard compound; INTERNAL_ID 8091 D004791 - Enzyme Inhibitors KEIO_ID I046
