    A high-throughput screen for inhibitors of the histone acetyltransferase, KAT6A, led to identification of an aryl sulfonohydrazide derivative that inhibited KAT6A with an IC50 of 0.87M. Elaboration of the structure-activity relationship (SAR) and medicinal chemistry optimization led to discovery of WM-8014 (84), a highly potent inhibitor of KAT6A (IC50 = 0.008 M). WM-8014 competes with Ac-CoA and X-ray crystallographic analysis demonstrated binding to the Ac-CoA binding site. Through inhibition of KAT6A activity, WM-8014 induces cellular senescence and represents a unique pharmacological tool.
