Quinoxalines

Quinoxalines (also called 1,4-diazanaphthalenes or benzopyrines) are bicyclic heterocycles containing a benzene ring fused to a pyrazine ring. Quinoxaline derivatives are important components of pharmacologically active compounds, including antibacterial, antibiotic, and antitumor agents, anti-fungal, anti-inflammatory, and analgesic activities, as well as use in RNA synthesis inhibition, reactive dyes and pigments, azo dyes, fluroscein dyes, corrosion inhibition, and photovoltaic polymers.
