Description

Olsalazine, also known as dipentum or olsalazine sodium, belongs to the class of organic compounds known as azobenzenes. These are organonitrogen aromatic compounds that contain a central azo group, where each nitrogen atom is conjugated to a benzene ring. It is sold under the name Dipentum. Olsalazine is a drug which is used for the treatment of inflammatory bowel disease and ulcerative colitis. Olsalazine gained Food and Drug Administration (FDA) approval in 1990. Olsalazine is an extremely weak basic (essentially neutral) compound (based on its pKa). Like balsalazide, olsalazine is believed to deliver mesalazine, or 5-aminosalicylic acid (5-ASA), past the small intestine, directly to the large intestine, which is the active site of disease in ulcerative colitis. The chemical name is 3,3' -azobis (6-hydroxybenzoate)salicylic acid. The drug is supplied by UCB Pharma. Olsalazine is an anti-inflammatory drug used in the treatment of inflammatory bowel disease such as ulcerative colitis. It is sold as the disodium salt. The Australian biotech company Giaconda has developed a combination therapy for treating constipation-predominant irritable bowel syndrome that uses olsalazine and the anti-gout drug colchicine.

2. Interferon gamma

General function:: Involved in cytokine activity
Specific function:: Produced by lymphocytes activated by specific antigens or mitogens. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons
Gene Name:: IFNG
