1,2,4-Triazolo[1,5-a]quinoxaline as a versatile tool for the design of selective human A3 adenosine receptor antagonists: Synthesis, biological evaluation, and molecular modeling studies of 2-(hetero)aryl- and 2-carboxy-substitued derivatives

A number of 4-oxo-substituted 1,2,4-triazolo[1,5-a]quinoxaline derivatives bearing at position-2 the claimed (hetero)aryl moiety (compounds 1-15) but also a carboxylate group (16-28, 32-36) or a hydrogen atom (29-31) were designed as human A3 (

Tricyclic Heteroaromatic Systems. 1,2,4-Triazoloquinoxaline

The parent 1,2,4-triazoloquinoxaline was prepared by a few-step reaction from N1-(2-nitrophenyl)-N3-ethoxalyloxamidrazonate, which afforded the key intermediate diethyl 1-(2-nitrophenyl)-1,2,4-triazole-3,5-dicarboxylate in sat
