Esteroides e Derivados
Os esteroides são compostos orgânicos que possuem uma estrutura de quatro anéis fundidos, conhecida como núcleo esteroide. Esse núcleo pode estar ligado a vários grupos funcionais que modificam suas propriedades e funções biológicas. Os esteroides desempenham um papel fundamental na regulação dos processos metabólicos e hormonais. São utilizados na medicina para tratar distúrbios inflamatórios, doenças autoimunes e desequilíbrios hormonais. Além disso, alguns derivados de esteroides possuem potentes propriedades anti-inflamatórias, como os corticosteroides. Em terapias específicas, são utilizados para reduzir a inflamação e controlar a dor em diversas doenças.
Na CymitQuimica, oferecemos uma variedade de esteroides e seus derivados para pesquisa e desenvolvimento farmacêutico.
