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.
