Pyrazines

Pyrazines (paradiazines) are heterocyclic six-membered aromatic compounds containing para nitrogen atoms. Pyrazine derivatives are known for antitumor, antibiotic, anticonvulsant, antituberculosis and diuretic activities, as well as kinase, enzymatic, and potent tubulin and FtsZ polymerization inhibition. Pyrazines are volatile compounds that are also of interest to the cosmetic, food, flavor, and fragrance industries.
