Application & Function
Sulfanilamide (CAS 63-74-1) is white granular or powder crystal,odorless. Taste slightly bitter. Slightly soluble in cold water, ethanol, methanol, ether and acetone, soluble in water, glycerin, hydrochloric acid, potassium hydroxide and sodium hydroxide solution, insoluble in chloroform, ether, benzene, petroleum ether. It is topical anti-inflammatory drugs.
As a sulfonamide antibiotic, sulfanilamide functions by competitively inhibiting (i.e., by acting as a substrate analogue) enzymatic reactions involving para-aminobenzoic acid (PABA). PABA is needed in enzymatic reactions that produce folic acid, which acts as a coenzyme in the synthesis of purines and pyrimidines. Mammals do not synthesize their own folic acid so are unaffected by PABA inhibitors, which selectively kill bacteria.
