2023年11月20日 · Fully unsaturated six-membered nitrogen heterocycles, such as pyridine, pyrazine, pyrimidine and pyridazine, have stable aromatic rings. Oxygen and sulfur analogs are necessarily positively charged, as in the case of 2,4,6-triphenylpyrylium tetrafluoroborate.
Pyrazine - an overview | ScienceDirect Topics
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.
Pharmacological activity and mechanism of pyrazines
2023年10月5日 · In this review, we have described the structure, bioactivities and mechanism of action of the most active pyrazine derivatives based on their structure. We found that five modification strategies have been used, and among these, fusing pyrazine with other heterocycles is the most studied variant.
