Sulfapyridine Chemical Properties,Usage,Production
Description
Sulfapyridine is a sulfonamide antibiotic with antibacterial and anti-inflammatory activities. It is also a metabolite of sulfasalazine formed through bacterial conversion in the colon. It is active against strains of Y. enterocolitica and Salmonella (MICs = 3.1-25 and 25-100 μg/ml, respectively), as well as S. aureus (MBC = 0.8 μM). It is an inhibitor of recombinant P. carinii dihydropteroate synthetase (DHPS; IC50 = 0.18 μM). Sulfapyridine scavenges peroxyl radicals in an oxygen radical absorbance capacity (ORAC) assay. It inhibits histamine release induced by compound 48/80 from isolated rat peritoneal mast cells in a dose-dependent manner. Sulfapyridine (1 μg/kg) also inhibits compound 48/80-induced systemic allergic reaction in rats. Formulations containing sulfapyridine have previously been used in the treatment of dermatological conditions and ulcerative colitis.
Chemical Properties
White to Off-White Solid
Uses
Used in treatment of dermatitis herpetiformis; antibacterial.
Uses
antibacterial, dermatitis herpetiformis therapy
Definition
ChEBI: A sulfonamide consisting of pyridine with a 4-aminobenzenesulfonamido group at the 2-position.
Antimicrobial activity
Like all sulfanilamides, this drug possesses antibacterial activity with respect to streptococci, pneumococci, staphylococci, meningococci, gonococci, colon bacillus, pathogenic dysentery, and so on. It is a long-lasting drug. Synonyms of this drug are bacillopirin, plurazol, sulfidin, and thiaseptol.
General Description
Sulfapyridine’s plasma half-life is 9 hours.This compound is a white, crystalline, odorless, and tastelesssubstance. It is stable in air but slowly darkens on exposureto light. It is soluble in water (1:3,500), in alcohol(1:440), and in acetone (1:65) at 25°C. It is freely soluble indilute mineral acids and aqueous solutions of sodium andpotassium hydroxide. The pKa is 8.4. Its outstanding effectin curing pneumonia was first recognized by Whitby; however,because of its relatively high toxicity, it has been supplantedlargely by sulfadiazine and sulfamerazine. Severalcases of kidney damage have resulted from acetylsulfapyridinecrystals deposited in the kidneys. It also causes severenausea in most patients. Because of its toxicity, it is usedonly for dermatitis herpetiformis.
Sulfapyridine was the first drug to have an outstandingcurative action on pneumonia. It gave impetus to the studyof the whole class of N1 heterocyclically substituted derivativesof sulfanilamide.
General Description
Odorless or almost odorless white or yellowish-white crystalline powder. Very slightly bitter taste. Aqueous solution is neutral.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Sulfapyridine is an amino acid. Slowly darkens on exposure to light . Soluble in both acidic and basic aqueous solutions
Fire Hazard
Flash point data for Sulfapyridine are not available; however, Sulfapyridine is probably combustible.
Safety Profile
Moderately toxic by intraperitoneal and intravenous routes. Slightly toxic by ingestion. Experimental reproductive effects. Human mutation data reported. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of NO, and SOx.
Synthesis
Sulfapyridine, N1 -(2-pyridyl)-sulfanilamide (33.1.21), is also synthesized by an analogous scheme from 4-acetylaminobenzenesulfonyl chloride and 2-amino pyridine.
Purification Methods
Crystallise sulfapyridine from 90% acetone and dry it at 90o. Its solubility in Me2CO, EtOH and H2O is 1.5%, 0.22% and 0.02%, respectively. [Winterbottom J Am Chem Soc 62 160 1940, Beilstein 22 III/IV 3978.]
