The quinoxaline core is considered a privileged scaffold as it is found in a variety of biologically relevant molecules. Here we report the synthesis of a quinoxalin-6-amine library, screening against a panel of cancer cell lines and a structure-activity relationship (SAR). This resulted in the identification of a bisfuranylquinoxalineurea analog (7c) that has low micromolar potency against the panel of cancer cell lines. We also show that cells treated with quinoxalineurea 7c results in caspase 3/7 activation, PARP cleavage and Mcl-1 dependent apoptosis.
