Sulfonamides and Derivatives
Sulphonamides are compounds that contain a sulphonamide functional group (-SO₂NH₂), where a sulphur atom is bonded to an amino group. They were among the first synthetic antibiotics used in medicine, inhibiting folic acid synthesis in bacteria, which gives them antimicrobial properties. They are mainly used to treat bacterial infections, although their use has declined due to antimicrobial resistance. In addition to their use as antibiotics, sulphonamides also have applications in the treatment of diseases such as malaria and inflammatory bowel diseases.
At CymitQuimica, we offer high-purity sulphonamides and their derivatives for research in microbiology and pharmaceutical development.

CAS:2-(4-Ethylphenyl)-propanoic acid is a supplement that is used to relieve pain and inflammation. It belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs). This drug has been shown to be efficacious in the treatment of osteoarthritis, rheumatoid arthritis, and bronchitis. 2-(4-Ethylphenyl)-propanoic acid inhibits both prostaglandin synthesis and leukotriene synthesis by inhibiting cyclooxygenase 1, which converts arachidonic acid into prostaglandins, and 5-lipoxygenase, which converts arachidonic acid into leukotrienes. This drug has also been shown to inhibit COX-2 production in human monocytes.
