Determination of pyrazinamide plasma concentrations using lc-ms and pharmacokinetics of pyrazinamide in patients with multidrug-resistant tuberculosis and in patients co-infected with multidrug-resistant tuberculosis and HIV [PDF]

open access: yes, 2013
Magister Pharmaceuticae - MPharmTuberculosis and HIV are arguably South Africa’s largest and most important health issues. With drug-resistant strains of tuberculosis on the increase and little research on new drugs, there is an urgent need for research ...

Effect of pyrazinamidase activity on pyrazinamide resistance in Mycobacterium tuberculosis [PDF]

open access: yesTuberculosis, 2009
Resistance of Mycobacterium tuberculosis to pyrazinamide is associated with mutations in the pncA gene, which codes for pyrazinamidase. The association between the enzymatic activity of mutated pyrazinamidases and the level of pyrazinamide resistance remains poorly understood. Twelve M.

Pyrazinoic Acid Inhibits the Bifunctional Enzyme (Rv2783) in Mycobacterium tuberculosis by Competing with tmRNA

open access: yesPathogens, 2019
Pyrazinamide (PZA) is a key drug for tuberculosis treatment. The active form of PZA, pyrazinoic acid (POA), appears to inhibit multiple targets in M. tuberculosis. Recently, the bifunctional enzyme Rv2783 was reported as a new target of POA. However, the

Insight to pyrazinamide resistance in Mycobacterium tuberculosis by molecular docking [PDF]

open access: yesBioinformation, 2009
Pyrazinamide (PZA) - an important drug in the anti-tuberculosis therapy, activated by an enzyme Pyrazinamidase (PZase). The basis of PZA resistance in Mycobacterium tuberculosis was owing to mutation in pncA gene coding for PZase. Homology modeling of PZase was performed using software Discovery Studio (DS) 2.0 based on the crystal structure of the ...

Pyrazinamide may possess cardioprotective properties [PDF]

open access: yes, 2019
Pyrazinamide is an anti-tubercular agent, used as a part of a three-drug regime (any three of the following: rifampicin, isoniazid, pyrazinamide, streptomycin or ethambutol) for the initial phase of treatment.

Pyrazinamide-3-Nitrophthalic Acid Cocrystals: Synthesis, Transformation, and Property Evaluation

open access: yes, 2023
The generation of multiple stoichiometric cocrystals from safe and nontoxic water is a rare occurrence. This study explored three different stoichiometric cocrystals (1:1, 1:2, and 2:1) of pyrazinamide-3-nitrophthalic acid cocrystals characterized by ...

Molecular investigation against the resistant mechanism of PncA mutated pyrazinamide resistance and insight into the role of pH environment for pyrazinamide activation

open access: yesJournal of Biomolecular Structure and Dynamics, 2019
Pyrazinamide (PZA), a crucial component of anti-TB therapy, is a prodrug. PZA interacts with PncA protein to be converted into its functional form i.e. pyrazinoic acid (POA). It has unique feature to kill dormant tubercle bacilli of acidic environment.
