What is the Mycobacterium tuberculosis drug target for pyrazinamide?

It is likely that PanD is a target of PZA and that POA binding to PanD could inhibit pantothenate and co-enzyme A biosynthesis, which is critical for central metabolism required for energy production and fatty acid metabolism in M. tuberculosis.

What bacteria is sensitive to pyrazinamide?

tuberculosis is uniquely susceptible to pyrazinamide, and this unique pyrazinamide susceptibility correlates with a deficient pyrazinoic acid efflux mechanism in this organism, whereas the naturally pyrazinamide-resistant Mycobacterium smegmatis has a highly active pyrazinoic acid efflux mechanism that quickly extrudes …

What is the cellular target of isoniazid?

The primary target of isoniazid is believed to be InhA, a NADH-dependent enoyl acyl carrier protein reductase involved in the synthesis of mycolic acid. The activated species, presumably an isonicotinic acyl radical, forms an adduct with the NAD radical.
