Application

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 .

Actions biochimiques/physiologiques

The active moiety of pyrazinamide is pyrazinoic acid (POA). POA is thought to disrupt membrane energetics and inhibit membrane transport function at acid pH in Mycobacterium tuberculosis. Iron enhances the antituberculous activity of pyrazinamide . Pyrazinamide and its analogs have been shown to inhibit the activity of purified FAS I.

Pyrazinamide is a paradoxical frontline tuberculosis drug characterized by high in vivo sterilizing activity but poor in vitro activity. This separation in pyrazinamide activity reflects differences between the in vivo tissue environment and in vitro culture conditions. The well-known acid

Thirty-four pyrazinamide-resistant and 37 pyrazinamide-susceptible Mycobacterium tuberculosis complex strains were analyzed for pncA gene mutations. None of the sensitive strains had any mutations, apart from silent mutations, whereas all but one resistant strain showed pncA mutations. By using sequencing as

Mycobacteria are known to acquire resistance to the antituberculous drug pyrazinamide (PZA) through mutations in the gene encoding pyrazinamidase (PZase), an enzyme that converts PZA into pyrazinoic acid, the presumed active form of PZA against bacteria. Additional mechanisms of resistance
