Possible mode of action of 5-aminosalicylic acid
Digestive Diseases and Sciences, 1987Despite the extensive use of sulfasalazine (SAS) and/or 5-aminosalicylic acid (5-ASA) in patients with inflammatory bowel disease and, more recently, rheumatoid arthritis, their mode of action has not been elucidated so far. None of the numerous pharmacological and biochemical effects described, including immunosuppressive, antifolate, and modulatory ...

The anti-oxidant properties of 5-aminosalicylic acid
Free Radical Biology and Medicine, 1996Oxidative damage to biological membranes is an important cause of tissue injury in inflammatory bowel disease. 5-Aminosalicylic Acid (5ASA) has therapeutic efficacy in Ulcerative colitis, which may be based on its antioxidant properties. We used Parinaric acid as a fluorescent marker of oxidation in an intestinal microvillous brush border membrane ...

5-Aminosalicylic Acid and Chemoprevention: Does It Work?
Digestive Diseases, 20135-Aminosalicylic acid (5-ASA)-containing drugs are the mainstay of therapy in inflammatory bowel disease (IBD). Intestinal inflammation is the main risk factor for colorectal cancer (CRC) in IBD. Hence, all drugs that are able to induce and maintain mucosal healing (MH) may prevent CRC risk in IBD.

Dextran-5-aminosalicylic acid ester (dextran-5-ASA) was synthesized as a colon-specific prodrug of 5-aminosalicylic acid (5-ASA) which is active against inflammatory bowel diseases. Chemical stability of dextran-5-ASA in the bath of pH 1.2 or 6.8 was investigated at 37 degrees C for 6 hrs, and 5-ASA was not released on such conditions. Depolymerization

SUMMARYSuppositories containing 300 mg 5‐aminosalicylic acid (1.96 mmol) or 425 mg acety1‐5‐aminosalicylic acid (1.96 mmol) were used in 40 patients with idiopathic proctitis to determine the efficacy of acetyl‐5‐aminosalicylic acid in treating this bowel inflammation.

5-aminosalicyl-L-aspartic acid (5-ASA-Asp) and 5-aminosalicyl-L-glutamic acid (5-ASA-Glu) were synthesized and their properties as colon-specific prodrugs of 5-aminosalicylic acid (5-ASA) were investigated employing rats as test animals. Incubation of 5-ASA-Asp and 5-ASA-Glu with the homogenates of tissue and contents of stomach or small intestine ...

As a new colon-specific prodrug of 5-aminosalicylic acid (5-ASA), 5-aminosalicyl-glycine (5-ASA-Gly) was prepared by a simple synthetic route in good yield. Apparent partition coefficients of 5-ASA-Gly were lower than those of 5-ASA, which determined in CHCl3/pH 6.8 buffer or n-octanol/pH 6.8 buffer system.
