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:Erythropoietin is a hormone that stimulates the production of red blood cells, and is used for patients with anemia. It is a recombinant human erythropoietin (rhEPO) that has been produced by genetic engineering. Erythropoietin binds to receptors on the surface of many types of cells, including those in the bone marrow. This binding stimulates the production of red blood cells from precursor cells in the bone marrow, and increases oxygen-carrying capacity in blood. The half-life of erythropoietin is approximately 36 hours. This drug also can be used to reduce high blood pressure and improve responsiveness to other drugs that are given intravenously. Erythropoietin can cause an increase in asialoglycoprotein levels in serum, which may be due to its effects on hepatocytes or erythrocytes.Pureza:(Capillary Zone Electrophoresis) Min. 98.0%Cholesterol propionate
CAS:Producto controlado<p>Cholesterol Propionate is a monolayer film-forming polymer that forms a polymeric matrix when combined with water. The thermal expansion of this material is dependent on the concentration of cholesterol propionate and can be used as a target tissue for multi-walled carbon nanotubes (MWCNTs). In addition, Cholesterol Propionate has been shown to have light emission properties due to its hydroxyl group and fatty acid content. The phase transition temperature of the material is dependent on the concentration of benzoate in the formulation. When it reaches the phase transition temperature, cholesteryl benzoate undergoes a phase change from crystalline to liquid at room temperature. This property can be used to activate MWCNTs within Cholesterol Propionate films, which then emit light.</p>Fórmula:C30H50O2Pureza:Min. 95%Peso molecular:442.7 g/mol20a-Hydroxy cholesterol
CAS:Producto controlado<p>20a-Hydroxy cholesterol is a model system for studying the effects of hydroxylation on fatty acid metabolism. The addition of one hydroxyl group to the 20 carbon position in cholesterol leads to an analog, 20a-hydroxycholesterol. This compound has been shown to inhibit the enzyme activities of 3-hydroxyacyl coenzyme A dehydrogenase and acyl coenzyme A:cholesterol acyltransferase. The inhibition of these enzymes leads to decreased production of both prostaglandin E2 and leukotriene B4, which are pro-inflammatory mediators. 20a-Hydroxycholesterol has also been found to be effective in treating skin cancer and adrenocortical carcinoma by inhibiting lipid synthesis, thereby reducing cell proliferation rates.</p>Fórmula:C27H46O2Pureza:Min. 95%Peso molecular:402.65 g/molδ6-Testosterone
CAS:Producto controladoDelta6-Testosterone is a natural steroid hormone that belongs to the group of steroid drugs. It is a potent androgen, or male sex hormone, which stimulates the development and maintenance of male sexual characteristics, including the growth of prostate gland and seminal vesicles. The effects of Delta6-testosterone are mediated by binding to and activating the Androgen Receptor (AR). The effects may also be increased when Delta6-testosterone binds to AR in combination with other hormones such as estradiol. Delta6-Testosterone is metabolized by the liver into testosterone through the cytochrome p450 enzyme system. This process begins with conversion of Delta6-testosterone into 6alpha-dihydrotestosterone (DHT) by 5a-reductase. DHT can then be converted into testosterone by 3beta-hydroxysteroid dehydrogenase/3alpha-hydroxysteroid dehydrogenase (3betaHSD) or 17beta hydFórmula:C19H26O2Pureza:Min. 95%Peso molecular:286.41 g/molSenecionine
CAS:<p>Senecionine is a n-oxide that is found in the plant Senecio jacobaea. It has been shown to have insecticidal, antiparasitic, and anticancer activity. The mechanism of senecionine's cytotoxicity is not well understood, but it may be due to its ability to cause mitochondrial dysfunction and cell lysis. Senecionine also binds to p2y receptors, which are a family of G protein-coupled receptors that are involved in inflammation and immunity. The binding of senecionine to these receptors leads to the activation of phospholipase C and inhibition of adenylate cyclase. This results in an increase in intracellular calcium levels and subsequent cell lysis.</p>Fórmula:C18H25NO5Pureza:Min. 95%Forma y color:PowderPeso molecular:335.39 g/molNorfluoxetine HCl
