Estándares farmacéuticos
Los estándares farmacéuticos son un conjunto integral de materiales de referencia esenciales para garantizar la seguridad, eficacia y calidad de los productos farmacéuticos. Esta categoría incluye estándares para ingredientes farmacéuticos activos (APIs), que son los componentes centrales responsables de los efectos terapéuticos. Además, abarca compuestos y metabolitos relevantes tanto para las industrias farmacéutica como veterinaria, proporcionando puntos de referencia para la medición y análisis precisos de estas sustancias. Los estándares de control de nitrosaminas son cruciales para detectar y mitigar las nitrosaminas potencialmente dañinas en las formulaciones de medicamentos. Los estándares de toxicología ayudan a evaluar la seguridad y los posibles efectos adversos de los compuestos farmacéuticos. Además, los estándares de activadores e inhibidores enzimáticos son vitales para la investigación y el desarrollo, permitiendo estudios precisos de las vías bioquímicas y los mecanismos de acción de los medicamentos. Estos estándares farmacéuticos son herramientas indispensables para el cumplimiento normativo, el control de calidad y la investigación, asegurando que los productos farmacéuticos cumplan con estrictos criterios de seguridad y eficacia.

CAS:<p>12-Amino-1-dodecanoic acid methyl ester hydrochloride salt (12ADM) has been shown to have immunomodulatory properties. It has a nanomolar range of activity, which is the optimal for an immunosuppressant. 12ADM inhibits the transcriptional activity of human immunodeficiency virus type 1 (HIV-1) and HIV-2, as well as other retroviruses, through interactions with specific RNA sequences in the viral genome. The amide group in this compound is essential for its antiviral activity, and it also interacts with betulinic acid to enhance its cytotoxicity.</p>Fórmula:C13H28ClNO2Pureza:Min. 95%Forma y color:PowderPeso molecular:265.82 g/mol7b-Hydroxy cholesterol 3b-acetate
CAS:Producto controlado7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.Fórmula:C29H48O3Pureza:Min. 95%Peso molecular:444.69 g/mol3a',4',7',7a'-Tetrahydrospiro[cyclopropane-1,8'-[2]oxa[4,7]methano[2]benzofuran]-1',3'-dione

CAS:Retinol is a form of vitamin A that is used for the treatment of insulin resistance. It can be synthesized by the body from all-trans-retinol, which is found in many animal and plant sources. Retinol can also be obtained from supplements, although it is poorly absorbed by the body. Retinol has been shown to improve insulin sensitivity in a cell culture model system, as well as in wild-type mice with diabetes mellitus. This drug has been shown to have strong anti-inflammatory effects and may also be useful for the treatment of hepatic steatosis. Retinol binds competitively to cellular retinoic acid receptors, leading to transcriptional activation of target genes, such as those involved in fatty acid metabolism.Fórmula:C20H32OPureza:Min. 95 Area-%Forma y color:Clear Viscous LiquidPeso molecular:288.47 g/mol1,8-Dinitropyrene
CAS:1,8-Dinitropyrene is a genotoxic and mutagenic potential agent. It has been shown to induce nitric oxide synthase activity in rat liver microsomes, which may be due to its ability to activate the redox potential of the cells. 1,8-Dinitropyrene also induces enzyme activities such as p450 and nitroreductase in rat liver microsomes. This chemical has an analytical detection limit of 0.05 ppm and can be used as a marker for environmental exposure. 1,8-Dinitropyrene is genotoxic and carcinogenic in rats but not mice. It has been shown to induce mutations at the thymidine position of calf-thymus DNA and is potent inducer of genetic mutation in vitro.Fórmula:C16H8N2O4Pureza:Min. 95%Forma y color:PowderPeso molecular:292.25 g/molγ-Dodecalactone
CAS:Gamma-dodecalactone is a naturally occurring fatty acid that exhibits antifungal and antitumor properties. The molecule is hydroxylated in vivo, forming an acid complex with the addition of water. This reaction produces a hydroxylate group, which increases the solubility of the compound. In vitro studies have shown that when gamma-dodecalactone is metabolized, it forms oxidation products such as nepeta cataria.Pureza:Min. 95%Atorvastatin
CAS:<p>Atorvastatin is a statin used to reduce low-density lipoprotein (LDL) cholesterol and triglyceride levels in the blood. It is marketed under the trade name Lipitor®. Atorvastatin inhibits the enzyme HMG-CoA reductase, which is responsible for the production of cholesterol. This drug also reduces plaque formation in atherosclerotic lesions by inhibiting inflammation and has been shown to be effective in reducing mortality from coronary heart disease. In addition, atorvastatin has a low incidence of side effects, particularly when compared with other statins such as simvastatin, pravastatin, or lovastatin. The risk of developing adverse reactions to this drug increases with age and prolonged use. The most common side effects are muscle pain or weakness, headache, nausea, high blood sugar levels (elevated glucose), and liver problems.</p>Fórmula:C33H35FN2O5Pureza:Min. 95%Forma y color:PowderPeso molecular:558.64 g/mol4-Nitrophenyl Anthranilate
CAS:Producto controlado<p>4-Nitrophenyl anthranilate is a potent inhibitor of serine protease. It is synthesized by reacting an anthranilate with an hydroxyl group in the presence of ultraviolet light, and can be used as a fluorescent probe. 4-Nitrophenyl anthranilate binds to the active site of serine protease, and prevents the hydrolysis of proteins by blocking the cleavage of peptide bonds at the carboxylic acid termini. This compound has been shown to inhibit human serum albumin and cell nuclei in vitro. The reaction mechanism for this compound is unknown, but it is believed that it may involve a photo-induced electron transfer mechanism.</p>Fórmula:C13H10N2O4Pureza:Min. 95%Forma y color:PowderPeso molecular:258.23 g/mol
