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.

CAS:<p>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.</p>Fórmula:C37H43FN2O5Pureza:Min. 95%Forma y color:White PowderPeso molecular:614.75 g/molNorethindrone Related Compound B CIII (Estr-4-ene-3,17-dione)
