Esteroides y derivados

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.

    <p>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.</p>
