Gene Information

Application

5-Aminosalicylic acid (5-ASA) has been used:
  • to synthesize 5-formyl-aminosalicylate-inulin to quantify its release during in vitro digestion and fermentation and compare the in vitro fermentation properties of the conjugated inulin to native inulin
  • in cell adhesion assay to study its effects on E-cadherin glycosylation and membranous turnover
  • to evaluate its effects on the neutrophilic inflammation index (NII) phenotype to study the effectiveness of the high cholesterol diet-gut inflammation (HCD-GI) platform

5-Aminosalicylic acid is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is brown in color and can be read spectrophotometrically at 450 nm. The reaction may be stopped with 3 N NaOH and read at 550 nm.

Biochem/physiol Actions

5-Aminosalicylic acid (5-ASA) is a first-line medicine, used to treat inflammatory bowel diseases like ulcerative colitis (UC). It has a high-efficiency rate in maintenance and induction of remission. 5-ASA is an active component of sulfasalazine and also consists of the carbohydrate polymer, inulin. It might exhibit anti-oxidant activity to lessen tissue injury. 5-ASA is vital for the prevention of T cell activation and proliferation. It negatively regulates cyclooxygenase and lipoxygenase pathways and lowers the formation of prostaglandins and leukotrienes. 5-ASA stimulates the membranous expression of E-cadherin and boosts intercellular adhesion.
