In this article, we describe the synthesis of 3-phenylquinoxaline-2-carbonitrile 1,4-dioxides bearing cyclic diamine residues at positions 6 or 7; the synthesis is based on the nucleophilic substitution of halogens. All synthesized 6(7)-aminoquinoxaline-2-carbonitrile 1,4-dioxides 3-6 demonstrated higher cytotoxicity and hypoxia selectivity compared to the reference agent tirapazamine against breast adenocarcinoma cell lines (MCF7, MDA-MB-231). The structure and position of the diamine residue considerably affects the anti
