Here we designed and synthesized sulfilimidoyl- and sulfoximidoyl-substituted analogs of the sulfone VE-821, a reported ATR inhibitor. The properties of these analogs have been investigated by calculating physicochemical parameters and studying their potential to specifically inhibit ATR in cells. Prolonged inhibition of ATR by the analogs in a Burkitt lymphoma cell line resulted in enhanced DNA damage and a substantial amount of apoptosis. Together our findings suggest that the sulfilimidoyl- and sulfoximidoyl-substituted analogs are efficient ATR inhibitors.
