Description and Uses

Pyrazinamide was synthesized in 1952, and it is the nitrogen-analog of nicotinamide. It exhibits hepatotoxicity. Synonyms of this drug are dexambutol, miambutol, esnbutol, ebutol, and others.

Pyrazinamide is used therapeutically as an antitubercular agent. Pyrazinamide is used to form polymeric copper complexes, create pyrazine carboxamide scaffolds useful as FXs inhibitors, and as a component of mycobacteria identification kits. It is used to study liver toxicity prevention and mechanisms of resistance .
