Stéroïdes et Dérivés
Les stéroïdes sont des composés organiques possédant une structure de quatre cycles fusionnés, connue sous le nom de noyau stéroïdien. Ce noyau peut être associé à divers groupes fonctionnels modifiant leurs propriétés et leurs fonctions biologiques. Les stéroïdes jouent un rôle clé dans la régulation des processus métaboliques et hormonaux. Ils sont utilisés en médecine pour traiter les troubles inflammatoires, les maladies auto-immunes et les déséquilibres hormonaux. De plus, certains dérivés stéroïdiens possèdent de puissantes propriétés anti-inflammatoires, comme les corticostéroïdes. Dans certaines thérapies spécifiques, ils sont utilisés pour réduire l’inflammation et soulager la douleur dans diverses maladies.
Chez CymitQuimica, nous proposons une variété de stéroïdes et de leurs dérivés pour la recherche et le développement pharmaceutique.
