Compostos Deuterados

Diethylene glycol d8 is a deuterated analog of diethylene glycol. It is synthesized from ethylene oxide and diethylene glycol by substitution of one hydrogen atom with deuterium. The sequences of this molecule have been determined, yielding a traceless product that can be used as a synthetic intermediate in the production of imidazoles. Diethylene glycol d8 is also used to study anions, acidic materials, and isotopic labeling. This compound has been methylated, butylated, or solvented to form different derivatives for use in studies on other molecules.

Benzidine D8 is a benzidine compound that has been shown to be carcinogenic. It is used in the production of dyes and colorants, and it is found in wastewater from dyeing factories. Benzidine D8 has been detected in human urine, which may be due to occupational exposure. This chemical can also be found in the environment as a result of industrial discharge. The carcinogenicity of benzidine D8 is mediated by its ability to produce reactive metabolites that bind to DNA, forming adducts. These adducts inhibit DNA replication and transcription, leading to cell death through inhibition of protein synthesis. Benzidine D8 undergoes metabolism via oxidative reactions with amines or hydrolysis with hydrophilic compounds such as alcohols or phenols, which are present at high levels in the bladder tissue. The risk of bladder cancer increases when benzidine D8 binds to these amines or hydrophilic compounds, resulting in the formation of reactive metabolites that can bind to DNA

Trideuteriomethylbenzene is a chemical compound that contains three deuterium atoms. It is a member of the class of compounds called alkyl-deuteriomethylbenzenes, which are used as proton donors in chemical reactions. It has been shown to be an effective supercritical solvent for the separation of long-chain alcohols from hydrocarbons. Trideuteriomethylbenzene may also be used as a photoelectron donor for the determination of time constants and depression constants by electron diffraction.

24,25-Dihydroxy vitamin D2 is a form of vitamin D that has been shown to be effective in the treatment of biliary cirrhosis and neonatal cirrhosis. It is synthesized from 25-hydroxyvitamin D3 by the enzyme 24-hydroxylase. The assay sensitivity for this compound is 10 ng/mL. This form of vitamin D has been shown to have an effect on serum bilirubin levels in patients with biliary cirrhosis. 24,25-Dihydroxy vitamin D2 can also be used to treat patients with chronic renal failure who are deficient in vitamin D3. The plasma concentration of 24,25-dihydroxyvitamin D2 is lower than that of 25-hydroxyvitamin D2 and 1,25-dihydroxyvitamin D2 because it is more rapidly metabolized by the liver.

4-Aminobiphenyl is a chemical compound that belongs to the group of aromatic amines. It is a human carcinogen and has been shown to cause cancer in animals. 4-Aminobiphenyl has been detected in the environment as an environmental pollutant and can be found in small quantities at low levels in food, air, and water. 4-Aminobiphenyl can be hydrolyzed by acid or alkaline hydrolysis to form its hydrolysate, which contains nitroarenes that are not present in the original compound. The DNA modification caused by 4-aminophenol may be due to its ability to modify DNA bases through reactive metabolites such as nitroarenes.

Rac-1,2-Bis-palmitoyl-3-chloropropanediol (rac1,2BPC) is a dispersive compound that has been used in the experimental phase of extraction. It has been shown to be efficient in the quantification and screening of fatty acids. Rac1,2BPC has also been used as a spiking agent for food samples to identify contaminants. The recoveries have been validated and linearity has been demonstrated. Rac1,2BPC is an anion that can be quantified by liquid chromatography with wavelength detection at 202 nm.

Dimethyl sulfoxide-d6, commonly called deuterated DMSO or DMSO-d6, differs isotopically from dimethyl sulfoxide (DMSO), in that the hydrogen atoms have been substituted by deuterium isotopes (2D). Dimethylsulfoxide-d6 is extensively used as an NMR solvent, which shows a characteristic shift observed at 2.50 ppm in 1H-NMR.

Alprazolam is a benzodiazepine drug used as an anxiolytic, anticonvulsant, and sedative. It is one of the most commonly prescribed drugs in the United States. Alprazolam-d5 solution is a solution that contains alprazolam labeled with D5. It can be used for wastewater treatment to identify the presence of trifluoroacetic acid (TFA) in wastewater samples. The dispersive solid-phase extraction method was validated for use with this labeled compound by detecting alprazolam-d5 at concentrations of 0.0025 µg/mL or less in urine samples within 10 minutes. Alprazolam-d5 solution has been shown to be stable in acidic pH environments and can be used for detection times up to 2 hours.

7-Hydroxy-4-cholesten-3-one-D7 (7OHCD7) is a metabolite of the bile acid, cholic acid. It is generated by the action of cholesterol 7α hydroxylase on cholesterol in the liver. It is excreted in bile, which is then absorbed back into the body from the gut and used for energy metabolism. 7OHCD7 has been shown to be an inhibitor of histone deacetylases, which are enzymes that regulate gene transcription. This inhibition leads to increased transcriptional regulation and reduced inflammatory responses in bowel disease models. 7OHCD7 has also been shown to increase cholesterol levels and reduce inflammation in humans with metabolic syndrome.
