Quinoxaline is a privileged pharmacophore that has broad-spectrum applications in the fields of medicine, pharmacology and pharmaceutics. Similarly, sulfonamide moiety considerable interest medicinal chemistry, as it exhibits wide range pharmacological activities. Therefore, therapeutic potential biomedical quinoxalines have been enhanced by incorporation group into their chemical framework. Th...
The malignant transformation of melanocytes causes several thousand deaths each year, making melanoma an important public health concern. Melanoma is the most aggressive skin cancer, which incidence has regularly increased over past decades. We described here preparation new compounds based on 1-(3,4-dihydroxyphenyl)imidazo[1,2-a]quinoxaline structure. Different positions quinoxaline moiety wer...
2-Chloro-3-methylquinoxaline was selected as a nucleus around which various molecular transformations were performed to obtain new compounds expected to possess optimized antimicrobial activity. As very little work regarding attachment of ether linkages replacing chlorine at C-2 has been reported, it was thought worthwhile to synthesize various quinoxaline derivatives by replacing the C₂ chlori...
A collection of 25 2-(2'-furyl)-1,2,4-triazolo[1,5-a]quinoxalines incorporating different substitution patterns at position 4 have been synthesized and their binding affinity towards human adenosine receptors (hA(1), hA(2A), hA(2B) and hA(3)) was determined. The biological data show that several potent at hA(1), but lightly selective, adenosine ligands were identified. Moreover, these results c...
