Pyrazine is a heterocyclic aromatic organic compound with the chemical formula C 4 H 4 N 2. It is a symmetrical molecule with point group D 2h. Pyrazine is less basic than pyridine, pyridazine and pyrimidine. It is a "deliquescent crystal or wax-like solid with a …

This is the first report to document the tobacco industry's incorporation of pyrazine compounds into cigarettes since the early 1970s which appear to contribute to the products’ appeal and abuse potential.

Pyrazine is a diazine that is benzene in which the carbon atoms at positions 1 and 4 have been replaced by nitrogen atoms. It has a role as a Daphnia magna metabolite. It is a member of pyrazines and a diazine.

Pyrazine is an aromatic azaheterocycle containing two nitrogen atoms, known for its electron-deficient nature. It is a key pharmacophore in various drugs, including anti-inflammatory, anticancer, and antimicrobial agents, with significant applications in pharmaceuticals, flavor, fragrance, and food industries.

pyrazine, any of a class of organic compounds of the heterocyclic series characterized by a ring structure containing four atoms of carbon and two of nitrogen. The pyrazine ring is part of many polycyclic compounds of biological or industrial significance.

2019年10月24日 · Pyrazine sequences are found in many compounds, which are the source of unique flavors and aromas in several foods and wines (Sumoto et al. 1991; Rohovec et al. 2010). Although pyrazines are widely studied as a flavor component of food, its derivatives are widely used in medicine, food, and chemicals.

2023年10月5日 · Pyrazine is a heterocycle common in drugs and natural products. In this review, we have described the structure, bioactivities and mechanism of action of the most active pyrazine derivatives based on their structure.
