Derivatives of pyrazine are very useful in the pharmaceutical, food, flavor and fragrance industries. For instance, phenazine is well known for its antitumor, antibiotic and diuretic activities. Tetramethylpyrazine has been reported to scavenge superoxide anions and decrease production of nitric oxide in human polymorphonuclear leukocytes.
