Pyrazinamide 生物活性

描述 Pyrazinamide (PZA) is an important sterilising tuberculosis drug that helps to shorten the duration of current chemotherapy regimens for tuberculosis. PZA is more active against old than against actively growing cultures. The highly diverse mutations in the PZase gene (pncA) that lead to loss of PZase activity cause PZA resistance[2]. PZA markedly inhibited the activity of M. tuberculosis FASI (the eukaryotic-like fas1 gene), the biosynthesis of C16 to C24/C26 fatty acids from acetyl-CoA[3]. PZA is hydrolyzed intracellularly to pyrazinoic acid (POA) by pyrazinamidase (PZase, encoded by pncA), an enzyme frequently lost in PZA-resistant strains, but the target of POA in Mycobacterium tuberculosis has remained elusive[1]. In plant cells, PZA is converted to pyrazinecarboxylic acid (POA), suppressing the activity of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO), the enzyme catalysing the final step of ethylene formation[4].
