Esteroides y derivados
Los esteroides son compuestos orgánicos que poseen una estructura de cuatro anillos fusionados, conocida como el núcleo esteroídico. Este núcleo puede unirse a varios grupos funcionales que modifican sus propiedades y funciones biológicas. Los esteroides tienen un papel clave en la regulación de procesos metabólicos y hormonales. Se utilizan en medicina para tratar trastornos inflamatorios, autoinmunes y desequilibrios hormonales. Además, algunos derivados esteroides tienen propiedades antiinflamatorias potentes, como los corticosteroides. En terapias específicas, se usan para reducir la inflamación y controlar el dolor en diversas enfermedades.
En CymitQuimica contamos con una variedad de esteroides y sus derivados para investigación y desarrollo farmacéutico.

Producto descatalogadoAtorvastatin lactam sodium salt impurity
CAS:Atorvastatin is a drug used for the treatment of hypercholesterolemia and cardiovascular diseases. Atorvastatin lactam, which is an impurity formed during the synthesis of atorvastatin, has been shown to inhibit cholesterol biosynthesis in a rat model. The in vivo metabolism of atorvastatin lactam was studied by HPLC-MS/MS and was found to be identical to that of the parent molecule. This impurity may be useful as a research and development or custom synthesis product, or as an impurity standard for HPLC analysis.Fórmula:C33H34FN2NaO6Pureza:Min. 95%Forma y color:White PowderPeso molecular:596.62 g/molChenodeoxycholic acid

CAS:Fórmula:C20H24O3Peso molecular:312.41Atorvastatin tert-butyl ester
CAS:Atorvastatin tert-butyl ester is an acid that is used to treat high cholesterol. It is a synthetic statin that inhibits the enzyme HMG-CoA reductase and blocks the production of cholesterol in the liver. This drug is administered orally, as a tablet or capsule, or in liquid form as a suspension. The drug has a bitter taste and evaporation may occur if it comes into contact with skin or clothes. Atorvastatin tert-butyl ester may be found in polymorphic forms (including dihydropyridine, dihydrospirocyclopentane, and dihydrobenzoquinoline). These forms are inactive, but can be activated by exposure to light or heat. These reactions produce an acidic compound that can react with other compounds to form new compounds.Fórmula:C37H43FN2O5Pureza:Min. 95%Forma y color:White PowderPeso molecular:614.75 g/molBetamethasone 17-Propionate-d5

CAS:Atorvastatin is a statin drug that inhibits the enzyme HMG-CoA reductase, which is responsible for cholesterol synthesis. Atorvastatin is used to lower LDL cholesterol and total cholesterol levels in the blood. It also lowers triglyceride levels and raises HDL cholesterol levels. Atorvastatin has been shown to inhibit fibrinogen production, reduce TNF-α production, and improve body mass index (BMI) in obese patients. This drug has been shown to be effective in reducing the size of atherosclerotic lesions by decreasing the amount of cholesteryl esters transferred from high-density lipoprotein (HDL) to low-density lipoprotein (LDL). It has also been shown to inhibit collagen production and stimulate muscle cell proliferation.Fórmula:C33H34FN2NaO5Pureza:Min. 95%Forma y color:PowderPeso molecular:580.62 g/molBudesonide Impurity 5
