生物活性:
Pyrazinamide (Pyrazinecarboxamide; Pyrazinoic acid amide) is a potent and orally active antitubercular antibiotic. Pyrazinamide is a proagent that is converted to the active form pyrazinoic acid (POA) by PZase/nicotinamidase encoded by the pncA gene in M. tuberculosis.
体外研究:
Pyrazinamide exhibits remarkable activity in vivo activity, has no activity against growing Mycobacterium tuberculosis except at an acidic pH. In M. tuberculosis, acidic pH enhances the intracellular accumulation of pyrazinoic acid (POA), the active derivative of PZA.POA is thought to disrupt membrane energetics and inhibit membrane transport function at acid pH in?Mycobacterium tuberculosis.
