Steroids and Derivatives
Steroids are organic compounds with a structure of four fused rings, known as the steroid nucleus. This core can be linked to various functional groups that modify their properties and biological functions. Steroids play a key role in regulating metabolic and hormonal processes. They are used in medicine to treat inflammatory disorders, autoimmune diseases, and hormonal imbalances. Additionally, some steroid derivatives have potent anti-inflammatory properties, such as corticosteroids. In specific therapies, they are used to reduce inflammation and manage pain in various diseases.
At CymitQuimica, we offer a variety of steroids and their derivatives for pharmaceutical research and development.
