A high-throughput screen for inhibitors of the histone acetyltransferase, KAT6A, led to identification of an aryl sulfonohydrazide derivative (CTX-0124143) that inhibited KAT6A with an IC50 of 1.0 HM. Elaboration of the structure-activity relationship and medicinal chemistry optimization led to the discovery of WM-8014 (97), a highly potent inhibitor of KAT6A (IC50 = 0.008 /mu M). WM-8014 competes with acetyl-CoA (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,
