| Chemical Properties | beige powder |
| Originator | Pamisyl,Parke Davis,US,1948 |
| Uses | Intended for use in Sigma Periodic Acid Staining Procedure, 395. Kit is intended for use with blood, bone marrow, tissue touch preparations or routine tissue sections. It is used for staining glycoproteins in polyacrylamide gels. Schiff's reagent is also sometimes used to dye organic tissues. It is been widely used for detection of a certain functional group in chemical solutions. |
| Uses | antimycobacterial antitubercular;NF-kB inhibitor.
4-Aminosalicylic acid (p-aminosalicylic acid, PAS), an antituberculosis drug, is a model active pharmaceutical ingredient to study salt and cocrystal formation in a multiple hydrogen-bonding functionality molecule with carboxylic acid, amine, and phenol groups.
It has also been used as a second line agent to sulfasalazine in people with inflammatory bowel disease such as ulcerative colitis and Crohn's disease.It is typically taken by mouth. |
| Uses | An antibiotic used to treat tuberculosis. |
| Definition | ChEBI: An aminobenzoic acid that is salicylic acid substituted by an amino group at position 4. |
| Application | 4-Aminosalicylic acid (4-ASA) can be used in the synthesis of:
Azo derivatives of 4-ASA with anti-inflammatory effects.
Ammonium 4-aminosalicylate salt polymorphs which are used as pharmaceutical ingredients.
Salicylic acid-triazole analogs which are used as quorum sensing inhibitors against Pseudomonas aeruginosa. |
| Indications | p-Aminosalicylic acid is a bacteriostatic that inhibits most tuberculous mycobacteria. In terms of tuberculostatic activity it is inferior to isoniazid and streptomycin. It is nephroand hepatotoxic, and is rarely used. A synonym of this drug is apacizin. |
