The new pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Initial amidoxime 1 was obtained in the reaction of pyrazinecarbonitrile with hydroxylamine. Upon treatment of amidoxime with methyl iodide O-methyl derivative 2 was formed. Both amidoximes were transformed into

Using resting cells of Rhodococcus rhodochrous J1, in which a large amount of nitrilase is induced, a simple and efficient bioconversion process for the production of pyrazinoic acid, an antimycobacterial agent, through catalysis by a nitrilase was developed. The reaction
Nicotinamidase/pyrazinamidase (PncA) is involved in the NAD+ salvage pathway of Mycobacterium tuberculosis and other bacteria. In addition to hydrolyzing nicotinamide into nicotinic acid, PncA also hydrolyzes the prodrug pyrazinamide to generate the active form of the drug, pyrazinoic acid, which
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
