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.

Skin fibrosis is a complex biological remodeling process occurring in disease like systemic sclerosis, morphea, or eosinophilic fasciitis. Since the knowledge about the underlying pathomechanisms is still incomplete, there is currently no therapy, which prevents or reverses skin fibrosis sufficiently.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
