Pyrazinamide is a paradoxical frontline tuberculosis drug characterized by high sterilizing in vivo activity but poor in vitro activity. Pyrazinamide is thought to act by the entrapment of pyrazinoic acid in the bacterial cell, leading to acidification and membrane damage. Consequently, the effects of weak acids and molecules affecting membranes added to pyrazinamide were studied.
