Sulfasalazine, a sulfa agent and a derivative of mesalazine, is used primarily as an anti-inflammatory agent. Target: Others Sulfasalazine (Azulfidine), used to treat pain and swelling in arthritis, belongs to a class of drugs called sulfa drugs.

Background Information

Sulfasalazine (brand name Azulfidine) is a sulfa agent and a derivative of mesalazine. Sulfasalazine inhibits in vitro growth of the human pancreatic cancer cell lines MIA PaCa-2 and PANC-1. Sulfasalazine also inhibits the cystine-glutamate antiporter, system Xc (SXC). Sulfasalazine, and its metabolite 5-ASA, are poorly absorbed from the gut. Its main mode of action is therefore believed to be inside the intestine. Sulfasalazine (Salazopyrin) induced T lymphocyte apoptosis in glioblastoma cell lines, modulated inflammatory mediators from both cyclooxygenase/5-lipoxygenase pathways and NF-κB signaling pathways, attenuated transcription of proinflammatory cytokines, and activated PPARγ. Sulfasalazine has long been used in treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. ......by AbMole BioScience
Sulfasalazine (brand name Azulfidine in the U.S., Salazopyrin and Sulazine in Europe and Hong Kong) was developed in the 1950s specifically to treat rheumatoid arthritis.Sulfasalazine is a sulfa agent and a derivative of mesalazine used primarily as an an ......by BOC Sciences
Sulfasalazine is a drug for the treatment of rheumatoid arthritis and ulcerative colitis. Sulfasalazine is reported to suppress NF-κB activity. ......by MedChemexpress Co., Ltd.
Sulfasalazine is used in the treatment of inflammatory bowel disease, including ulcerative colitis and Crohn's disease. It is also indicated for use in rheumatoid arthritis and used in other types of inflammatory arthritis (e.g. psoriatic arthritis) where it has a beneficial effect. It is often well tolerated compared to other DMARDs. In clinical trials for the treatment of chronic alcoholics, sulfasalazine has been found to reverse the scarring associated with liver cirrhosis. ......by MedKoo Biosciences, Inc.
