Research Area: Infection
Biological Activity:
Pyrazinamide (Pyrazinoic acid amide) is an agent used to treat tuberculosis. M. tuberculosis has the enzyme pyrazinamidase which is only active in acidic conditions. Pyrazinamidase converts pyrazinamide (Pyrazinoic acid amide) to the active form, pyrazinoic acid which accumulates in the bacilli. Pyrazinoic acid inhibits the enzyme fatty acid synthase (FAS) I, which is required by the bacterium to synthesise fatty acids although this has been discounted. [1]

包装
10, 25, 100 g in poly bottle
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 1 and mechanisms of resistance 2.

Biochem/physiol Actions
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 3. Pyrazinamide and its analogs have been shown to inhibit the activity of purified FAS I.

Antibacterial (tuberculostatic).

CHEBI:45285 

A monocarboxylic acid amide resulting from the formal condensation of the carboxy group of pyrazinoic acid (pyrazine-2-carboxylic acid) with ammonia. A prodrug for pyrazinoic acid, pyrazinecarboxamide is used as part of multidrug regimens for the treatment of tuberculosis.
