Several [1,2,4]triazolo[4,3-a]quinoxalines that were reported as antidepressants in the patent literature were found to possess moderate affinity for the adenosine A1 and A2 receptors. On the basis of structural parallels with adenine and adenosine, the N-cyclopentyl derivative was synthesized and found to have improved affinity and selectivity for the A1 receptor. In the N-cyclopentyl series, affinity was optimal with trifluoromethyl substitution at the 1-position, resulting in a compound (9) with 7.3 nM A1 affinity and 138-fold selectivity for the A1 receptor.

Abstract: Synthesis of 2,3-disubstituted 1-alkylpyrrolo[2,3-b]quinoxalines was accomplished through the reaction of 3-chloroquinoxalin-2-amines with internal alkynes in the presence of Pd(OAc)2, NaOAc, and KOtBu in DMSO. This method afforded desired pyrrolo[2,3-b]quinoxalines in 65?92% reaction yields. The minimum inhibition concentration and minimum bactericidal concentration determinations against Micrococcus luteus and Pseudomonas aeruginosa revealed that some of the synthesized compounds showed the same values compared to tetracycline. These compounds could be used in the future research for the development of new antibiotics. Graphical Abstract: [Figure not available: see fulltext.].

Various oxepine and azepine fused N-heterocyclic derivatives were synthesized using a new and one-pot reaction of 2,3-dichloro quinoxaline/pyrazine with 2-(1H-indol-2-yl)phenol/aniline in the presence of 25 mol% FeCl3. The reaction proceeded via C-C bond followed by C-X (X = O or N) bond formation to construct the central 7-membered ring, affording the desired products in good yields. The structure assignment was confirmed by the single crystal X-ray analysis of a synthesized oxepine fused N-heterocycle derivative. Most of the synthesized compounds were found to be promising when tested for their anti-proliferative properties against cervical and breast cancer cell lines.
