Abstract

A series of novel 2-arylamino-3-(arylsulfonyl)quinoxalines was synthesized through a newly developed approach. All synthesized target compounds were screened for their cytotoxicities against cancer cell lines including PC3, A549, HCT116, HL60 and KB. Representative compounds with favorable cytotoxicities were tested for their PI3Kα inhibitory activities. Among the synthesized target compounds, 17 (PI3Kα IC(50): 0.07 μM) displayed the most potent cellular activities (IC(50) values of 0.14 μM, 0.07 μM, 0.95 μM and 0.05 μM against PC3, A549, HCT116 and HL 60, respectively).
