Steroidi e Derivati
Gli steroidi sono composti organici con una struttura a quattro anelli fusi, nota come nucleo steroideo. Questo nucleo può essere legato a vari gruppi funzionali che ne modificano le proprietà e le funzioni biologiche. Gli steroidi svolgono un ruolo chiave nella regolazione dei processi metabolici e ormonali. Sono utilizzati in medicina per il trattamento di disturbi infiammatori, malattie autoimmuni e squilibri ormonali. Inoltre, alcuni derivati degli steroidi possiedono potenti proprietà antinfiammatorie, come i corticosteroidi. In terapie specifiche, vengono impiegati per ridurre l’infiammazione e controllare il dolore in diverse patologie.
Presso CymitQuimica, offriamo una varietà di steroidi e loro derivati per la ricerca e lo sviluppo farmaceutico.
